Meet Jack from Ilan

Flowering at JLBG since early March is the little-known Jack-in-the-pulpit, Arisaema ilanense. This collection hails from Ilan (Yilan), in northeastern Taiwan, and for us is the very first arisaema to flower each winter, even when temperatures are still quite cold. The mature size is only 4-6″ in height, so this is one for a very special site in the rock garden. There are very few plants of this species in ex-situ conservation collections, so thanks to JCRA Director, Mark Weathington for sharing. Our specimen has been in the garden since 2016. Hardiness is unknown, but we’re guessing Zone 7b-9b.

Sweet as Snow Cream

Edgeworthia chrysantha ‘Snow Cream’ is a 2000 Juniper Level Botanic Garden/Plant Delights introduction that has proven to be one of our most popular introductions. We made the original selection from a group of seed-grown plants, imported from China by Canada’s Piroche Plants in the late 1990s. We were drawn to this seedling because of the particularly large flowers, and large leaves that reminded us of a plumeria. Let me be clear that all Edgeworthia chrysantha seedlings are nice, but there is certainly a significant difference between flower and leaf sizes of seed-grown plants.

Below are photos from our winter open nursery and garden days this year, where our garden specimens never cease to amaze visitors with both its sweetly scented flowers and amazing floral show. Sadly, no matter how many we propagate, it never seems to be enough to meet the demand. A more open site results in a much better floral show. Hardiness is Zone 7a – 10b.

Rolfing in the Garden

Starting in late winter, the amazing blue-flowered South American Ipheion ‘Rolf Fiedler’ begins its stunning floral show in the garden. This rare native, which has only been found on the top of two hills in Uruguay, has yet to be formally assigned a confirmed species name, although some botanist believe it to be Ipheion peregrinans. Growing much lower to the ground than it’s South American cousin, Ipheion uniflorum, this un-named species spreads nicely in dry soils, either in full or part sun.

If you’re taxonomically inclined, the entire Genus ipheion has been bounced back and forth between a series of other genera for the last century, so we’re waiting for the taxonomic dust to settle before changing tags. Ipheion has previously been included in a number of other genera including Beauverdia, Brodiaea, Hookera, Leucocoryne, Milla, Nothoscordum, Tristagma, and Triteleia. Not only is the genus in question, but ipheion has now been moved from the onion family (Alliaceae), where it resided for a century to the amaryllis family (Amaryllidaceae).

For now, we’re just enjoying “rolfing” in the garden.

Tiger by the Tongue

What a lovely color echo we caught this week at JLBG when the tiger swallowtails were visiting Mertensia virginiana (Virginia Bluebells). Remember that botanical diversity results in more pollinators in the garden.

A Forest of Pink

Magnolia ‘Forest’s Pink’ put on a splendid show this year in early to mid-March. Sold as a cultivar of the Chinese Magnolia denudata, some magnolia experts insist that it’s actually a hybrid, due to the intensity of the pink color as well as the form of the plant.

Magnolia ‘Forest’s Pink’ originated as an introduction from Treseder’s Nursery in Cornwall, England, who propagated and named it from an original introduction from China by Scottish botanist, George Forrest (1873 – 1932), that was growing at England’s Caerhays Castle.

Magnolia denudata, a typically white-flowered species, native to Central China, has been cultivated around Buddhist monasteries since 618 AD…in other words, nearly 1,500 years. Another long-cultivated Chinese native magnolia with pink flowers and an overlapping native range is Magnolia liliiflora. The commonly known hybrids of the two species are known as the Magnolia x soulangeana hybrids. Since plant explorer George Forest was known to collect both in the wild as well in cultivated areas, it is quite probably that the magnolia that bears his name is not pure Magnolia denudata, but actually a Magnolia x soulangeana hybrid. Looks like someone will need to do some DNA work to sort out this nomenclatural tussle.

Whatever you want to call it, our 25 year-old specimen of Magnolia ‘Forest’s Pink’ was rather stunning this March. Thankfully, the flowering was mostly complete before our mid-March freeze of 23 degrees F.

Japanese Princess Sedge

Carex conica ‘Hime’ has been in horticultural commerce for many decades, and remains a superb woodland garden sedge. The evergreen species Carex conica is native throughout Japan, where it occurs in woodland conditions. This variegated selection that goes by an array of names such as ‘Snowline’ and ‘Marginata’, but Carex conica ‘Hime’, which translates to “princess” seems to the the correct cultivar name. The tight 10″ tall x 20″ wide clumps of narrow white-edged leaves are topped with this fascinating floral show for us in early March. In 35 years of growing this, we have yet to see a single garden seedling.

Voles in Holes

This is the time of year (October – April) when voles are extremely active in the garden, as you can see below from this recently chewed aspidistra in the garden. Voles are vegetarian mouse relatives that tunnel underground eating the roots of plants…usually those with the most expensive price tags. Once the roots are gone, plant remains are then stealthily pulled underground so you won’t notice the damage.

The formulation of most commercial vole baits changed in the last few years and are now composed of Vitamin D (Cholecalciferol). While Vitamin D is quite effective on voles, it still needs to be kept away from pets, since too much Vitamin D isn’t a good thing. We prefer the large blocks, compared to the smaller pellets since they are less likely to be swallowed by pets.

We’ve also always recommended using PVC-tubes for vole feeding, or simply bury the bait underground or under a rock, etc. Of course, there’s always the option of using mouse traps to catch voles, which is much more labor intensive and not really really viable on a large scale.

Vole bate stations should be placed every 10′ apart in high problem areas, and must be checked every couple of weeks to make sure bait remains. We have been using various vole baits for 35 years, and have yet to have any issues with our fleet of garden cats, but it is important that you be careful with bait placement.

Once vole populations are under control, we recommend using traps around the edge of your property to prevent new intrustions. We do this by spreading a square of black plastic with bait underneath, along your property line…every 50′ or so seems to be adequate. The voles are attracted to the black plastic and the bait, so this way there never venture further into the garden.

Happy Weeper

Prunus ‘Pink Cascades’ is a recent introduction from NC State’s Tom Ranney. This strict weeper can be staked to any desired height, then allowed to trail from there. Here are our stunning two year-old plants this March, grafted at 4′ tall. The plants have already reached 11′ in width on the way to 20′ – 30′ wide.

NC State/JLBG Day of Giving

Wednesday, March 23, 2022 is the NC State University Day of Giving…a time for those who want to support activities at NC State. In our case, that means the endowment we are building to preserve Juniper Level Botanic Gardens. If you care about ensuring the gardens remain intact for future generations, please consider making a contribution to the endowment. You can do so at this link to the University Endowment Fund for JLBG.

For those who are relatively new to the gardens, here is a link to a historical timeline of the JLBG garden development.

Fritters in the Garden

We’ve made a regular habit of killing fritillarias (the bulb…not the fried food) in the garden, especially those ungrowable brightly-colored species like Fritillaria imperialis that tantalizingly appear each fall in the major bulb catalogs.

Although it lacks the bling of it’s showier cousins, the species that is reliable for us in the garden is Fritillaria thunbergii. This native of Kazakhstan has naturalized in both western China and Japan, where it has been used medicinally for almost 1,000 years as a treatment for respiratory ills. There is still some debate among botanists whether some of the Chinese population might actually be native as well.

In the garden, Frittilaria thunbergii emerges in February, and is full flower at 2-3′ in height by early March. As with most spring ephemerals, it has gone to sleep by early May. Light shade or part sun seems to suit it fine. Hardiness is at least Zone 7a-8b.

Raisin’ Cain

I had a great visit recently with David Cain and Denny Werner. Most of you know Dr. Werner from his work at NC State, first as a peach breeder and later as the creator of a parade of amazing redbud hybrids.

David and Denny were both grad students together back at Michigan State. Dr. Cain went on to become a fruit breeder, and is the papa of the incredibly famous Cotton Candy grape. On the off chance you haven’t tried it, be sure to search for it at your local grocery store. David worked in academia and later the USDA, before embarking on his own venture, where he made several incredible fruit breeding breakthroughs.

I didn’t realize David is a long-time plant nerd and Plant Delights customer, and has recently moved from California to the East Coast for his next plant breeding adventure. We had a blast talking plant breeding and looking at a few of our crazy breeding projects at JLBG.

Ginger drama in the Garden

One of the fun reasons to grow plants from seed is that each seedling is different…unless you’re growing highly bred annuals. Most non-hybrid seedlings will be under the bell curve, meaning they all look and behave relatively similar. As plant collectors, we get excited when one appears that falls outside the bell curve. An example is our wild ginger selection, Asarum maximum ‘Floragasma’, which has both far more flowers than we typically see with the species, but it also flowers 2-3 weeks before our other clones. Winter hardiness is Zone 7b-9b.

An Exciting New Expedition

Please join me in welcoming our newest JLBG team member, Dr. Patrick McMillan. I’ve known Patrick for 30 years, going back to his days as a student at UNC-Chapel Hill, and long before he became a legend in the plant world.

We’ve followed his amazing journey, most recently as Director of Heronswood Gardens in Washington. Prior to that, he was Director of the SC Botanical Garden and Professor of Environmental Sustainability at Clemson since 2000. Patrick was the Emmy Award winning host of the renown PBS series, Expeditions with Patrick McMillan. Patrick is a highly-respected botanist/naturalist, who has won far too many awards to mention, but we’ll let Patrick tell you a bit more about himself and why he decided to partner with JLBG.

My first experience with Juniper Level and Tony was sitting at the kitchen table in 1991, the inaugural year of Plant Delights Nursery, talking about Asarum and star-struck by Tony’s knowledge and passion that has continued to grow into one of the world’s premier gardens and nurseries. In those days I dreamed of the opportunity to work alongside such talented horticulturalists and intrepid explorers.

My love of plants and all things slithering, creeping, crawling, and flying came at a very early age. I can’t remember a time when my life wasn’t centered on them. Fast forward 31 years and I found myself sitting at the same table reminiscing about the past, marveling at how far JLBG has grown, and stirring excitement for the future. I am so enthusiastic about joining the staff at JLBG, learning from the lifetimes of incredible knowledge and skill that is assembled among the employees and sharing my own experience, passion, and knowledge to bolster the mission and the horticultural and conservation accomplishments of this magical place.

I’m probably best described as a plant nerd. I have never met a plant I didn’t love. Every plant has a story and each is connected to our lives and the lives of the biodiversity upon which we all depend. Much of my horticultural experience and focus in South Carolina and at Heronswood Garden in Kingston, Washington has been focused on generating and supporting insect, bird and other wildlife diversity in the home landscape.

My philosophy of natural community gardening and the generation of life is a fairly simple one based on filling every space with life – diversity generates diversity. My exploration of the plant world has taken me from pole to pole and over every continent except Australia. I was trained as a sedge taxonomist but my interests include anything with cells. I’ve described new species ranging from ragweeds to sedges and begonia.

I also believe strongly that our greatest gift is sharing knowledge and I have worked as a lifelong educator. You may also have seen me on your local PBS station, where for 15 years I wrote, hosted, and produced the series “Expeditions with Patrick McMillan” – distributed by American Public Television. Conservation, preservation and generation of life is at the core of my life’s mission and I can imagine no better place to be nested within than JLBG. I hope to meet you soon and share some hearty plant nerd conversation.

Crazy Eddie’s Dunce Cap

In our cold frames, some plants will occasionally flower out of season, and that’s the case this week when one of our Orostachys ‘Crazy Eddie’ plants decided to flower out of season…fall is it’s normal time. The offseason timing won’t adversely affect the plant, and it did give us an unexpected photo moment. Because of the form of the flower, orostachys gained the common name, dunce caps, named after the pointed caps that poorly performing students were forced to wear. Of course, you’re probably showing your age if you knew what dunce caps were.

Aucuba…the overlooked winter shrub

It was great during our recent winter open house to see so many folks noticing the aucubas in the garden. Of course, they are hard to miss with our collection of over 140 different taxa. There are few evergreen plants better for year-round interest in dry shade than aucuba. Here is one of the most fascinating ones that’s in flower now in early March, Aucuba himalaica var. dolichophylla. This little-known, narrow-leaf species hails from 3,000′ elevation in several southern Chinese provinces. Winter hardiness Zone 7a-9b, and perhaps a bit colder.

Winter Pricks

Most hardy cactus have the good sense to wait until spring to flower, but not Notocactus haselbergii. This gem, which hails from Southern Brazil, started to bloom the first of March, and will continue on and off most of the summer. It has thrived for several years in our crevice garden.

Striking Gold

Trillium cuneatum ‘Oconee Gold’ is a rare gold-flowered selection of the typically purple-flowered southeastern toadshade. We found our original plant of this in Oconee County, SC, and have propagated them from seed since that time. If we keep the yellow-flowered plants isolated from purple-flowering clones, we have more than 50% that reproduce with yellow flowers. The time from seed to flower is usually five years. Winter hardiness is Zone 5a-8b.

Sakhalin Fern

The dainty rock garden fern, Woodsia polystichoides has just emerged in the garden. The spores for this were shared by one of our Russian gardening friends from his collection on the Sakhalin Islands. For those who don’t follow history, the Sakhalin Islands were another of Russia’s many conquests, this from a 2 week war with Japan in 1945, when neither country was behaving neighborly. What a shame that countries aren’t run by gardeners. Hardiness is Zone 4-7b.

Woodsia polystichoides

The Elusive Red Witch Hazel

Flowering this week at JLBG is the amazing cherry red Hamamelis japonica ‘Tsukubana-kurenai’, also known as Shibamichi’s Red witch hazel. This gem was selected by legendary Japanese nurseryman, Akira Shibamichi, who also introduced Metasequoia ‘Ogon’. We were blessed to have Mr. Shibamichi visit JLBG back in the 1990s.

Open House Visitors

We truly love having garden visitors! We recently wrapped up our winter Open Nursery and Garden days, and will open in again in spring in late April/early May. It’s great to see folks get ideas both about plants they would like to try as well as garden design ideas. Because of exceptionally good weather most days this winter, the crowds were record-setting.

Open house is also like a giant horticultural family reunion. It’s actually surprising when folks don’t run into their gardening friends in the garden. We love seeing old friends, while meeting new ones. Below is George McLellan, a long time friend and avid plantsman from Virginia and member of the mid-Atlantic Rhododendron Society. On the left is Barbara Bullock, who recently retired from the US National Arboretum after 29 years of curating the garden’s azalea collection…here for her first visit.

Geroge McLellan (c), and Barbara Bullock (l)

The prize for the traveling the farthest distance this year goes to hosta nurseryman, Marco Fransen of Holland. I had the pleasure of visiting Marco’s nursery several years ago, so it was lovely to have the chance to chat. It was interesting to learn that Marco’s main customer base for new hosta introductions is both Russia and Ukraine. It would be safe to conclude that the current conflict in that region won’t be good for business, but our thoughts and prayers go out to everyone effected.

Intermingling in the Garden

We love intermingling plants, often planting more than one type in the same space, where their growth habits allow them to comfortably co-exist. Here is a three year-old planting where we used ‘Gold Queen’ Hyacinth among a patch of our North American native groundcover juniper, Juniperus horizontalis ‘Bar Harbor’. Despite what many folks seem to think, there are no laws that plants in the garden can’t touch each other, so how about some more hand-holding in the garden.

Canary Treasure

This is our first flowering of Dracunculus canariensis, the rare cousin of the more commonly-grown aroid Dracunculus vulgaris. Dracunculus canariensis hails from Madeira (reportedly extinct) and the nearby Canary Islands, all off the coast of Morocco.

We inherited our specimen from the late plantsman, Alan Galloway, who planned to cross it with Dracunculus vulgaris. The task now falls to us. Both species have a similiar chromosome count of 2N=28, so this should be a easy cross by saving pollen. To us, the flower smells like watermelon rhine, which is a nice change from the more offensive smell of its sibling.

Beyond Bread

What do the plants pictured below have in common, and it’s not what you might think. These common plants are actually food crops…read more at the end of the photos.

Cosmos sulphureus
Nepeta (catmint)
Polymnia
Tanacetum parthenium (feverfew)
Cyperus (nutsedge)

These are a few of the plants that can be used to make wheat bread…and flavorful bread at that. Yes, the kind you eat.

A fascinating 2017 research study from Tavria State Agrotechnological University in Ukraine describes how common garden plants (and weeds) can be used in the production of bread. Most people probably have little idea of the amazing research that goes on in Ukraine. If you’re curious to give it a try, here is the link to the original research publication.

Our thoughts and prayers are with the Ukrainians as they endure the horrific invasion of their wonderful country.

Richer for Ritchie

I was scanning some older slides recently, and came across this image of the late Ritchie Bell from 1968. Dr. Bell was director of the NC Botanical Garden in Chapel Hill for 25 years, from 1961 to 1986. Here he is in 1968, posing by a sign for the first nature trail opened at NCBG, just a couple of years earlier.

Ritchie is not just known for his work at the garden, but for his many books, most notably, his contributions to the revered, 1964 Manual of the Vascular Flora of North Carolina, with Al Radford and Harry Ahles. We’ve never forgot Ritchie’s motto of “Conservation through Propagation”…something that’s even more important today in the face of a changing climate. Ritchie passed away in 2013 and the age of 92, but his powerful legacy endures.. He was a good friend and an incredible inspiration.

Ritchie had just made a previous presentation to the Men’s Garden Club of America regional meeting in Reidsville about the new NCBG trail system. Below is an image from that 1968 meeting with MGC Regional President, Sam Fairchild (r) of Reidsville, NC. Most people don’t remember Ritchie prior to growing his trademark beard.

Cracking Crocus

Spring crocus are popping all through the garden, and it’s a challenge to photograph them all. We just happened to recently catch Crocus isauricus ‘Spring Beauty’ in full flower. Crocus isauricus (formerly Crocus biflorus ssp. isauricus) is an endemic to Southern Turkey in the region along the Mediterranean Sea.

Glowing Podocarp

Podocarpus macrophyllus ‘Okina’ is looking lovely this winter. This Japanese selection has resided at the base of a large pine tree at JLBG since 2001. We love the white speckled foilage, which really shines in the winter months. Podocarpus macrophyllus is one of a short list of conifers that thrives in the shade of a woodland garden. Our 20 year old plant is now 6′ tall. Hardiness is Zone 7b-10b.

Rockin’ along

A couple of weeks ago, we mentioned our landscaping project on the north side of Mt. Michelle to create more intricate planting pockets, while raising the planting heights significantly via the use of rock assisted berms.

Phase 2 of the project was to create a cut through on northwest side through a previously inaccessible bed. Phase 2 is now complete, and visitors can now traverse the new path, exiting into the northwest side of the Mt. Michelle waterfall. This path takes you under the large speckled-leaf loquat, Magnolia macclurei, and several large conifers, so be sure to look up as well as down.

Phase 2 new path cut through on the north side of Mt. Michelle

Last week, Jeremy and his staff tackled phase 3 of the project, which was the two 50 degree slopes on the west side of Mt. Michelle. Despite being planted for some time, we had lost some soil due to runoff, and the plants were screaming for more compost, and we were screaming for more rock pockets.

In less than a week, Jeremy’s team stacked these new retaining planting walls, which provide hundreds of new planting pockets for small woodland treasures. Each is now filled with our garden compost mix as well as an array of small, little-known plants. Just remember, if you garden on flat ground and think you are out of planting space, the key is to learn to think like a Pythagorean…a² + b² = c²…go vertical.

You’ll be able to see these newly planted areas during our winter open house, although it will take a while for the plants to mature.

Iris days of Winter

Here are an assortment of Iris species flowering at JLBG during the last week of February. So many folks only know the bearded iris of later spring, and miss these amazing winter gems. Join us this weekend for our Winter Open Nursery & Garden Days and explore our winter blooming iris.

The first is Iris tuberosa, a winter blooming tuberous iris from Mediterranean Europe. Iris tuberosa is one of the few examples, where a Latinized name change actually results in something that’s easier to pronounce. This gem was formerly known by the tongue twisting name, Hermodactylus tuberosus. Most iris grow from rhizomes, with the tuberous iris being a much smaller and less-known group. We have found these to grow best in part sun. Winter hardiness Zone 7b-10b.

Iris tuberosa

The West-Asian (Caucuses, Iran, Turkey, and Russia) Iris reticulata is also different, in that it grows from a bulb. These are quite easy to grow, and are available commercially in a number of named color forms. Below is Iris reticulata ‘Painted Lady’…looking stunning today. The reticulate (netted) iris grow best in full to part sun. Hardiness is Zone 3-8.

Iris reticulata ‘Painted Lady’

We’ve shown some of the Mediterranean Iris unguicularis recently, but here are a couple more looking particularly nice this week…Iris ‘Front Drive’ (top) and Iris ‘Winter Echos’ below. Hardiness for both is Zone 6b-9b.

Iris unguicularis ‘Front Drive’
Iris unguicularis ‘Winter Echos’

Streaked like a Comet

We treasure any plant that makes a great woodland groundcover, and are particularly smitten with the ophiopgon (mondo grass) and liriope (monkey grass) selections. We currently grow over 120 different ophiopogon accesions including quite a number of wild collections, at JLBG…see what a touch of OCD does for you. We’ve grown Ophiopogon ‘Comet’ since 1997, and love it for its white striped foliage and well-behaved growth habit. Hardiness is Zone 7b-10b.

Rad Windflower

Flowering now in the woodland garden is this rad little windflower, Anemone raddeana. This Asian native (China, Japan, Korea, and Russia) is a plant you’ll almost never see for sale. First, it flowers in the middle of winter when few people are thinking about gardening. Secondly, it’s ridiculously small, producing only a single white flower per stalk, which rises only a couple of inches from a slowly creeping rhizome. Third, it’s a spring ephemeral, meaning it will be dormant by the first of May. Finally, most people move through life too fast to even notice little gems like this. That said, if you like things like this, this is exactly the kind of thing you’ll really like. We certainly do!

Dainty Dirca

Few people know the fascinating native shrub, Dirca palustris. It’s little wonder it gets overshadowed by showier members of its family, Thymelaeaceae, which includes the likes of Daphne and Edgeworthia. Our 6′ tall plant is flowering alongside a large edgeworthia, and rarely gets noticed by visitors.

Dirca palustris, the plant, is actually widespread across Eastern North America, with a range from Canada to Florida, where it thrives in slightly moist, acidic soils. It’s often known as leatherwood, due to its thick, but very pliable branches, which have been used by Native Americans for making rope as well as baskets.

There are three other less poorly known dirca species…if that’s possible. We grow the rare Dirca decipiens from Kansas/Arkansas, but have not yet tried D. occidentalis from California, or D. mexicana from Mexico.

The genus takes its name from the Dirce in Greek Mythology, who bit the big one while tied to the horns of a bull….a truly sordid story. The specific epithet “palustris”, lacks the fascinating story of the genus, but only means that the plant naturally lives in very wet sites. Winter hardiness is Zone 3-9.

Beautiful Madness

I borrowed the title from our good friend Jim Dodson’s book for this post about Ulmus parviflora ‘Golden Rey’. One of the most admired trees in our garden is our specimen of Gold-leaf lacebark elm. The bark, as you can see below is absolutely fabulous both in winter and summer.

Ulmus parviflora ‘Golden Rey’

The problem is that lacebark elm is a notorious seed producer, and in our garden, it seems like every one germinates. Our love/hate relationship with this species has so far resulted in the removal of four different mature cultivars from our garden so far.

Here’s where genetic engineering (GE) could actually help. Notice, we are using the term GE, as compared to the incorrectly used GMO. All, plants, unless they come directly from the wild, are genetically modified organisms (GMO). Humans would cease to exist as we know them without GMO’s, so, please try to use the correct terminology. What people are crusading against in food crops is actually genetic engineering (GE). Hoping down now from my soapbox.

It’s actually quite easy to sterilize a plant, using one of the genetic engineering tools known as CRISPR. Just think of this GE surgery as a horticultural vascectomy…a couple of snips and you’re done making babies. It will be interesting to see if public sentiment for non-edible crops allows genetic engineers to solve such problems with making some amazing plants like the widely planted lacebark elm more palatable to gardeners who are concerned about its potentially invasive tendencies.

Cinnamon in the Garden

Ever since seeing cinnamon trees (Cinnamomum camphora) planted throughout the parking lot at Florida’s Disneyworld in the 1970s, we have been fascinated to see how many species of Cinnamon trees are winter hardy here in Zone 7b. Cinnamomum jensenianum, from Southern/South Central China has been one of the stars in our trials. Here is our 15 year old specimen looking great in mid-winter.

Cyclamen and Cyclawomen

Here are a couple of images this week from the garden of our older clumps of Cyclamen hederifolium. For garden areas that are dark and dry, where nothing else grows, cyclamen are your best bet. Of the plants below, one is at the base of a cryptomeria and the other at the base of a pine. Although they flower from August until Christmas, the winter foliage is just hard to beat. Hardiness is Zone 4a-8b.

Remembering Rosenwald

I continue to be shocked how many people I speak with that have never heard about Rosenwald Schools. It’s truly puzzling that it manages to be overlooked in our American History classes. Last year we mentioned the renovations taking place at the Panther Branch Rosenwald School, just three doors north of Juniper Level Botanic Garden (JLBG). We promised to keep you updated, so here goes.

If you missed our original blog, here is a brief history of the partnership that produced the Rosenwald Schools. In the early part of the 20th century, Sears & Roebuck president, Julius Rosenwald (1862-1932) teamed up with renowned African American education leader, Booker T. Washington (1856-1915) of the Tuskegee Institute, to try and remedy the chronically underfunded, segregated education system for African American children.

Washington and Rosenwald worked together to fund construction of state-of-the-art middle schools for African American students around the country. Between 1913 and 1932, 5,350 schools (and associated structures) were constructed thanks to a matching grant program (1/3 Rosenwald funds, 1/3 local government funds, and 1/3 community funds) devised and set up by Rosenwald and Washington.

The Rosenwald schools were based on designs by the country’s first accredited black architect, Robert R. Taylor of the Tuskegee Institute. These plans were later standardized by Samuel Smith of the Rosenwald Foundation. Some Rosenwald schools accommodated as many as seven teachers, while others had only one. The schools, which were all conceived to also be used for community functions, were designed based on daylight considerations and the effect on the light on student eye strain. All schools have an east/west orientation, along with pale colored walls and expansive windows.

The recently renovated Panther Branch Rosenwald School

The 3,000 square foot Juniper Level/Panther Branch Rosenwald School, operated from 1926 until 1956, and is one of only sixty remaining Rosenwald Schools in existence. In their heyday, North Carolina had more Rosenwald Schools than any other state. Now that renovations are complete, the Rosenwald School is available for community events, and at night is used to tutor area students.

Juniper Level Missionary Baptist Church (JLMBC), which owns the Panther Branch Rosenwald School property, was first established in 1870 in a small log building, which continued to expand, culminating in the current main building, which was constructed circa 1920. Other adjacent structures were added later as the church grew.

Visionary Pastor Jeff Robinson of JLMBC has graciously allowed us to become a partner in efforts to improve and strengthen the community of Juniper. In our case, this primarily involves landscape work around the schoolhouse.

Pastor Jeff Robinson in the Panther Branch Rosenwald School

In fall 2021, I was blessed wit the opportunity to attend a luncheon at the school with Mrs. Perry, below. Not only was Mrs. Perry, 92, a graduate of the Panther Branch Rosenwald School, but she went on to become a career school teacher. She shared amazing stories of the 200-300 students that attended the Rosenwald School, each walking from miles around. She talked about the amazing sense of community in the Juniper community, which didn’t suffer from the racial barriers that plagued many southern towns. She explained how the first student to school each morning was tasked with starting a fire in the pot-bellied stove that was the sole source of heat on cold mornings.

Mrs. Perry speaking at the Rosenwald School

JLMBC is also a Food Bank distribution site, so the first project for our staff was to build a community garden behind the Rosenwald School, where church members will grow their own organic produce to distribute. We enriched the soil with the same compost we use at JLBG, and worked with the church volunteers, who installed the deer fence.

Step two was the installation of a Magnolia grandiflora hedge between the cemetery behind the school and the adjacent fire station. Due to the narrow strip of land available, we used the naturally narrow selection Magnolia ‘Southern Charm’ (aka Teddy Bear magnolia).

Step 3 was installing foundation plants around the building, which will take a couple of years to fill in.

Plantings around the Rosenwald School

Step 4 will be the planting of Camellias and Azaleas on the newly built berm on the north side of the school to serve as a screen for the construction of Interstate 540..

Step 5 is to build a nature park/picnic area in a wooded plot adjacent to the vegetable garden. When we began clearing the undergrowth, we found an amazing canopy of trees and a range of moisture regimens that would lend itself to becoming an area for the community to learn and enjoy.

Adjacent to the school, and along Sauls Road, were two large oaks, one red oak, and one live oak. With 54″ diameter trunks, both likely were 100-150 years old, probably dating to the founding of Panther Branch and the construction of JLMBC. Sadly, crews working on the construction of the nearby I-540 decided both should be removed, despite not being anywhere near the highway. Before we knew what was happening and could muscle any resistance, all that remained were two 12′ tall stumps.

Because these trees had great historical significance to both the church and school, we reached out for help in saving a slab from the live oak, which could be preserved and eventually dated. The folks at Bartlett Tree answered our call for help, and volunteered their crew to salvage a slab that we will now cure and prepare for display in the Rosenwald Historical Room. Hooray to Bartlett for their interest in this community project and willingness to help!

As we prepare for our winter open house, The church has agreed to open the Rosenwald School at 9109 Sauls Road for tours during our winter open house hours, which you can find here. Parking is available at the Church on the west side of Sauls Road, as well as the school on the east side of Sauls Road. We hope everyone will take time to stop by this important historical landmark and learn more about the amazing collaboration that created the Rosenwald Schools.

All spruced up and nowhere to grow.

Picea rubens (red spruce) is one of only 8 US native spruce species, and the only one whose natural ranges includes North Carolina. The entire range of red spruce starts in Nova Scotia and continues south to high elevations in the NC mountains. Genetic testing indicates that our red spruce evolved due to climate change during the Pleistocene (12,000 years to 2.5 million years ago), when it split off from Picea mariana (black spruce). Black spruce is now the only other nearby spruce, which currently resides from New Jersey north with a small population in Northern Kentucky.

Surprisingly, red spruce is virtually absent from piedmont gardens, probably due to the common wisdom that it doesn’t tolerated heat and humidity. As long as it’s given adequate amounts of Calcium (we aim for a pH of 6.5), it grows beautifully. Here is our 26 year old specimen, that didn’t get the memo that it’s shouldn’t grow here. Hardiness is Zone 3a-8a.

Red spruce wood is used to make high quality wood instruments like violins and acoustic guitars, but to avoid cutting down your lovely specimen, we recommend you stick with products that can be made from the foliage, like the infamous Red Spruce Beer.

Florida trilliums

When people think of trilliums, they usually think of the cold north, but states like Florida are also home to four species of trilliums which all thrive throughout the southeastern states. Here are two of the earliest species to flower in our garden.

The first is Trillium maculatum ‘Kanapaha Giant’ from Alachua County. This is consistently the earliest trillium to emerge and flower for us. This is followed close behind by Trillium underwoodii. Both of these are usually in flower by early February.

Trillium maulataum ‘Kanapaha Giant’
Trillium underwoodii ‘Dazzler’

Palm-leaf Oxalis

One of our winter garden favorites is looking so good right now, that we had to share. Oxalis palmifrons is an amazing, but slow-growing rock garden gem, that hails from the South African karoo. We offered this through Plant Delights almost a decade ago, and it will be some time before we have enough to offer again.

Oxalis palmifrons

Snowdroppin’

We’ll never be accused of being galanthophiles (folks who are hopelessly addicted to collecting galanthus cultivars), but we do love the genus, and are fascinated with these mostly winter-flowering bulbs. Here are a couple in full flower now at JLBG. These have a preference for slightly moist-to-average woodland conditions.

Galanthus ‘Sam Arnott’
Galanthus plicatus ‘Beth Chatto’

Cherry Bomb

The superb (and spineless) Ilex ‘Cherry Bomb’ is looking amazing in the garden this week. Our specimen is now 22 years old, and measures 35′ tall x 15′ wide. It originated at the US National Arboretum as part of Dr. William Kosar’s breeding program, and is a 1959/1960 seedling from Ilex ‘Nellie R. Stevens’, most likely a hybrid with the spineless Ilex integra.

It was sent around to different growers for evaluation trials under a code #, and was later determined to not have enough value for northern US growers, so a destruction notice was sent by the National Arboretum.

Like some characters in the slasher flicks, it wasn’t completely destroyed, as propagations from the holly managed, quite improperly, to make its way to the deep south, where growers found it quite extraordinary, and in the 1980s, it was given the name Ilex ‘Cherry Bomb’ by Dr. Dave Creech of Steven F. Austin University. This wonderful plant is now a staple in the Southern nursery industry.

Burned baby, burned

With our recent 16 degree F winter temperatures, all of the cycas plants (sago palms) in the garden now have fried foliage. This foliage will not recover, but damage like this is fully expected in our climate, and not something that will damage the plants. Be sure to not remove the old damaged foliage this early, however, since cycads are programmed to shoot out new foliage 10-14 days after the old foliage is removed, and this is much too early for new foliage, with more cold weather likely on the way.

We like to remove the old foliage starting in mid-April, when it should be safe. As you can see in the second photo, the central crown is still in great shape, undamaged by the cold temperatures. We think the central crown is one of the most fascinating parts of a cycad, which shows its’ ancient lineage.

A Little Diamond

Cryptomeria japonica ‘Little Diamond’ is one of our favorite dwarf Japanese cedar selections, this one from Holland Konjin Nursery prior to 1990. This specimen at JLBG is five years old and measures 2′ tall x 3′ wide. At maturity, we have seen these reach 4′ tall x 8′ wide.

Plant Imposters

The first plant looks for all the world like a fine textured carex, but in fact, it’s an iris. Iris dabashanensis is a little-known species from China, that thrives for us in light shade, but will also take a few hours of early morning sun. Our plant is a Darrell Probst collection from Sichuan, China. Winter hardiness is Zone 5a -8a.

Iris dabashanensis

Below is the same plant flowering in early April.

Iris dabashanensis

The other plant growing nearby in our gardens that fools even the keenest plantsmen is this liriope look-alike. In fact, this is a cast iron plant, Aspidistra linearifolia. This demonstrates why those pesky taxonomic traits matter. In 2008 we introduced a selection with a lighter central stripe down the center of each leaf called A. linearifolia ‘Skinny Dippin’ which we will be offering again in 2023. Winter hardiness is Zone 7b and warmer.

Aspidistra linearifolia

Weeping cast irons

Most gardeners know the genus aspidistra (cast iron plant) from one or two species, and if that’s the case, you probably only know those which hold their leaves vertically upright. There are equally as many species with pendant leaves, which provide a completely different form in the woodland garden. Here are two of those pendant-leaf species from the garden this week.

The first is Aspidistra sichuanensis, which is one of the larger growing species. A single clump can easily spread to 6′ in width in a couple of decades. This clump has topped out at 3.5′ in height.

Aspidistra sichuanensis

Below that is Aspidistra ebianensis ‘Flowing Fountains’. With narrower, wavier foliage, it makes a large clump, albeit slightly smaller than Aspidistra sichuanensis. Both plants are winter hardy from Zone 7b and south.

Aspidistra ebianensis ‘Flowing Fountains’

Ice n’ Roses Dilemma

Below are more of the Ice n’ Roses snow roses flowering now in the gardens at JLBG. These amazing sterile hybrids were created in Germany by the Heuger plant breeding company. They have proven fabulous in our trials, but are still often difficult to find due to the screwy production cycle.

Because these snow roses, as Heuger calls them, are clonal and sterile, they can only be commercially produced by tissue culture, which is all done overseas. The non-rooted microplants are shipped in sterile containers to the US, where they are received at rooting stations (nurseries capable of putting roots on these microplants).

Helleborus x glandorfensis ‘Ice n’ Roses Pink’

There are only three North American rooting stations used by Heuger, one in Canada, and one on each of the US coasts. Once the microplants have roots and have grown large enough, they are purchased by finish growers, who pot and grow them for 2-3 months before they are a saleable size.

For a finish grower or retail nursery to have plants available to sell in late winter or early spring, they would need to receive liners (small plants with roots) from the rooting stations in September/October. The problem is that these rooting stations usually get their unrooted microplants from overseas in fall, when their losses are less and the plants finish faster.

Helleborus x glandorfensis ‘Ice n’ Roses Red’

Consequently, these rooting stations only have plants available for the finish growers from February – April. This means that the finish grower and retailer will only have plants ready to sell at the beginning of summer, which is certainly not ideal unless you live in the northern tier of states or Canada.

The only option a finished grower has is to hold the plants through the summer and fall, to have them available in the late winter flowering season. This drives up the crop cost dramatically, since a nursery has an overhead cost per square foot per month of growing space. Until a change is dictated by the grower throughout the supply chain, it is unlikely that the supply will be able to keep up with the potential demand. Anyone think making plants available is easy?

Helleborus x glandorfensis ‘Ice n’ Roses White’

The Spectrum of Siblings

Throughout the years, we’ve grown literally thousands…perhaps 10s of thousands of seedlings of the Japanese sacred lily, Rohdea japonica. Each one varies slightly, but we only save those at the far end of the bell curve. Here are three of our seedlings which well represent that dramatic variation at each end of the spectrum…a wide leaf form we named Rohdea ‘Stork Nest’ (15 yrs old), a very narrow leaf form we named Rohdea ‘Thin Man’ (16 years old), and a miniature that has yet to be named.

Arisarum in hiding

We were delighted to find a flower on our Arisarum simorrhinum in early February, tucked in a the base of a dwarf Chamaecyparis (false cypress). This little-grown Mediterranean native, dryland aroid is first cousin to the better known mouse plant, Arisarum proboscideum. This baby has been in the ground for 20 years, so slow is the operative word.

Arisarum simorrhinum

Rocking and Rolling in the Winter Garden

If you’ve visited JLBG, you know how much we love working with rocks, so we continue to find new areas to plant more. We’ve recently tackled two long overdue projects near the Mt. Michelle waterfall.

The first was re-working the Mt. Michelle watercourse we know as Mystic Creek (named after one of our late cats). When this was installed in 2003, we used concrete to form the water channel. Well, after 18 years, tree roots had their way with the concrete, which lost both the battle and the war.

After a fair amount of root excavation work, Jeremy and Nick installed a new rubber liner, with rocks along the edge. We’ll probably wait until spring to finish the replanting in order to avoid planting on top of something that was winter dormant. Below is the new rocked watercourse.

Phase 2 of the project was re-working an adjacent bed, where light levels had changed dramatically since it was installed in 1998. Originally a full sun bed, the shrubs on the west side have grown substantially, leaving us with a bed that only gets 3-4 hours of sun on one end, and a full shade area underneath the canopy.

Here, we raised the center of the bed, with more of Jeremy and Nick’s rock work, which was then filled with our on-site created compost. This created a visual barrier to much of the winding path that visitors use to get closer to the small plants, which are now tucked in the crevices.

One the back (west) side, Jeremy and Nick installed another small rock seating area, of which there are never enough.

There are a few more days of rock work to complete Phase 2, then we’ll start on Phase 3, which will rework the west face of Mt. Michelle, with more boulders to create additional planting pockets. We hope you’ll check out the progress at our upcoming winter open house.

Raising Rabieas

We have long loved small crevice-sized succulents, but have also killed far more than our share, due mostly to our wet, cold winters. The newest star in our trials is the South African, Rabiea albipuncta, a first cousin to the better known, Delosperma. We should mention, that new DNA research has actually suggested a name change to Nananthus vittatus would be more correct, so we’ll be re-tagging shortly.

This gift from Denver Botanic Garden plantsman extraordinaire, Panayoti Kelaidis, has thrived in the gardens since 2018. We actually tried this back in 2004, but our site simply didn’t drain well enough in winter. This image was taken here at JLBG on February 2 this year, which shows how insanely tolerant the flowers are of cold weather. We hope to make this available next year through Plant Delights Nursery. This gem forms a substantial caudex, and as such is highly prized by bonsai enthusiasts.

Rabiea albipuncta

Snowgaves

We’ve “enjoyed” frozen precipitation for three consecutive weekends this winter, with one producing a decent 3.5″ snow. There’s something magnetic about snow on century plants, that makes you grab your camera and snap away.

The white of the snow looks out of place on an agave, although it does wonders for accenting the architectural structure of the plant. We have worked for 35 years to identify and create agaves which are completely tolerant of such weather events. Below are a couple of our hybrids, created here at JLBG.

Agave x amourifolia
Agave x loferox

Where firs fear to tread

Here’s a photo we took during our recent snow event of the amazing Abies bornmuelleriana (Turkish Fir). Not bad for out hot, humid, Zone 7b climate! It’s hard to imagine that there are beds of agaves growing nearby.This specimen is now 24 years old. Winter hardiness is Zone 5a-8b.

No running allowed

Fargesia robusta is one of the many excellent clumping bamboos for the garden. Thriving in light shade to part sun, this evergreen gem tops out around 7′ in height. We know it’s still hard for some people to realize, but clumping bamboos truly cannot run. This garden specimen at JLBG is now 22 years old. We love both the texture and architecture of bamboos. Winter hardiness is Zone 7a-8b.

Fargesta robusta

Early lenten rose

Every year, we grow thousands of lenten roses from our own seed collections in the garden. Most, we sell at our Winter Open Nursery and Garden as Helleborus x hybridus ‘Winter Delights’. All of our Winter Delights hellebores are hand selected by color after they flower. Every now and then, an incredibly unique form gets pulled for the gardens and here is one of those from a few years ago. This amazing plant has huge 3.5″ wide flowers, and was already in full flower by January 1. We hope everyone can visit our upcoming Winter Open House and see the amazing hellebore selections in the garden.

Finally, a ferner adapts

Since ferns are one of the groups on which we focus our ex-situ conservation efforts, we have collected a huge number of species and selections from around the world. One that has continually frustrated us is the miniature rock fern, Asplenium trichomanes. Although this small gem is native to every continent except Antartica, we have struggled to keep it alive.

In our travels, we have collected it from Europe to Africa, but have also managed to kill all of those collections in the garden. Since our first attempt in 2004, we have now killed Asplenium trichomanes 16 times. We believe, however, in the late JC Raulston’s mantra, “Unless you are killing plants, you aren’t growing as a gardener.” The key is how many times do you continue to try before giving up?

We’re pretty stubborn as long as we feel we keep learning from each failure. Our latest accession of this species, which came as spores from Russia’s south coast, is actually thriving in our crevice garden, where the pH is north of 8.0. It seems that the crevice habitat is the answer.

Ruscus Crazy

We love the evergreen ruscus in garden, but realize they are a plant that will never be found at most mainstream garden centers. A genus of only 6 currently recognized species, native from Europe into Eurasia, these horticultural oddities are so odd that they once qualified to have their own plant family, Ruscaceae.

Now, with improved DNA testing, they were found to actually be members of the Asparagus family. Exactly where within the Asparagus family is still an ongoing debate. Within the last decade, they were grouped with Nolina and Dasylirion, which to those of us who work with live plants, made no sense. Most likely, they will wind up in their own section, but as distant cousins to better know genera like Rohdea and Liriope.

Ruscus are great evergreen plants for dry shade, in regions where they are winter hardy, which is usually Zone 7b and south. Ruscus are unique in that they don’t produce leaves, but instead have leaf like structures known as cladodes, from which the tiny flowers emerge. All ruscus species have both separate male and female plants, although there are four hermaphroditic (bi-sexual) cultivars of Ruscus aculeatus in commerce, which produce the lovely red fruit without a mate.

The most common ruscus species in cultivation is Ruscus aculeatus, which has a wide range from Western Europe through the Caucuses. A handful of named cultivars of Ruscus aculeatus can be found in the gardens. Below is a photo this month of Ruscus ‘Sparkler’ a self-fruiting form, whose 2′ tall height is mid-way between Ruscus ‘Elizabeth Lawrence’ and Ruscus ‘Wheeler’.

Ruscus aculeatus ‘Sparkler’

Ruscus hypophyllum is a species, which ranges from Spain to Northern Africa, that’s rarely cultivated in the US. Other than the very tender Ruscus streptophyllus, this has proven to the be the next most tender species. Prior to trying these new forms of Ruscus hypophyllum, which were planted in early 2020, we had only grown a single clone, which had consistently died in our Zone 7b winters. These new plants are seedlings, grown from an Alan Galloway seed collection in Majorca, Spain.

Ruscus hypophyllum

Ruscus hypoglossum, which hails from Italy to Turkey, is a similar sounding species that we were fortunate to study in the wilds of Slovenia a few years ago, where it grew in mountainous open forests.

Ruscus hypoglossum
Ruscus hypoglossum flowers

Ruscus x microglossum (below) is a natural hybrid between Ruscus hypophyllum and Ruscus hypoglossum…quite a tongue-full.

Ruscus x microglossum

Ruscus colchicus is a species we fell in love with during a trip to Hillier’s Arboretum in 2005. Hailing from NW Turkey to the Western Caucuses, Ruscus colchicus is possibly the most elegant garden species. We are fortunate to have three different clones growing at JLBG, which we hope to one day have enough to share.

Ruscus colchicus

Voted least likely to be found in an ex-situ plant collection is Ruscus hyrcanus, a species, whose native range is from the Crimea into Iran. In appearance it somewhat resembles a dwarf, horizontal-growing version of Ruscus aculeatus. We are thrilled to have been able to offer this little-cultivated species in the past through Plant Delights.

Ruscus hyrcanus

We hope you’ll take notice of these great evergreens during your next visit to JLBG.

Winter Magnolias

This winter has been an amazing one at JLBG for the mid-winter flowering, evergreen magnolias. Formerly known as Michelia, there are several species from warm temperature Asian climates, which flower in the mid-winter. The plant in the top photo is our oldest specimen of Magnolia platypetala, and below is Magnolia macclurei…both planted in 1999, and in full flower in January. Obviously, we will loose open flowers if winter night temperatures drop too far below freezing, but the remainder of the flower buds usually open shortly after temperatures warm.

Also, the bright gold shrub in the first image is the original plant of our introduction, Illicium parviflorum ‘Florida Sunshine’…the plant from which all plants in the world were propagated. To the lower right is the Mediterranean native, Phlomis fruticosa ‘Miss Grace’. All in all, a lovely winter garden combination.

Tender Mason’s Lily

Here is the reportedly tender Massonia depressa from South Africa in full flower in our crevice garden. I should add that this photo was taken 2 nights after we recorded 16 degrees F. I guess when the source of all worthwhile information, Wikipedia, says “When cultivated in a temperate environment, M. depressa does not tolerate freezing temperatures, so must be grown under glass in a cold greenhouse or similar.” we should take that as fake gardening news. Hmmm.

Massonia is a genus of bulbs in the Asparagus family, related to the more familiar genus scilla. Winter hardiness of this species is….well, still to be determined, but we’re good to at least Zone 8b so far.

Ichang Winter

Another of the mid-winter flowering species of wild ginger is the Chinese Asarum ichangense. Here is a green leaf form of this easy-to-grow wild ginger in late January from the top. If you push aside the leaves, you’ll see the amazing floral show, hidden beneath. Winter hardiness in Zone 6b-8b, and possibly colder.

Mid-Winter Grotto

Here’s a mid-winter shot of our front grotto, showing what that section looks like during the most trying time of year. We try to emphasize to those building new gardens to treat gardens just like rooms of your home. Each should have a floor, ceiling, walls, furniture both large and small, and decorations. In the garden, we also try to emphasize year round interest, which in our area includes a good selection of evergreens. Our Winter Open Nursery and Garden Days coming up in a few weeks is a great time to get ideas and inspiration for your own garden. Below is a “before” picture of the same area.

JLBG grotto garden 2022

Below is the same shot when this section was begun in 1988.

A Characias Cracker

For years, we struggled to grow the Mediterranean/Balkan native spurge, Euphorbia characias…until we discovered its secrets. First, it isn’t a long lived plant to begin with…in most cases 3-5 years is it, so you’ll need to plant it where it’s likely to reseed. That would be well-drained slopes that are either mulched or covered with gravel.

Secondly, after it flowers in spring with its stunning show of yellow flowers, remove most of the flower stalks as soon as flowering has finished, except those needed to produce new seedlings (the flowers are also great to use in floral arrangements). If not, the seed stalks use up energy causing the plant to decline much faster. We’ve now allowed this to seed throughout the slopes in front of our house, and here is the result…a smattering of 3′ tall x 3′ wide clumps, photo taken mid-winter.

Although this section of the garden, planted in compost-amended sandy loam is irrigated, we typically don’t recommend irrigation for this spurge without excellent drainage. You’ll also read on-line that Euphorbia characias doesn’t like hot, humid summers…another example of fake gardening news that just keeps getting repeated without any concern for the facts.

We’ve also found Euphorbia characias to grow well in part sun under large trees, which keeps the soil dry. The plants will never be as dense as they are in full sun, but they survive and flowers. There is really not anything else that gives you this evergreen blue color and form in the winter garden.

Winter Sunburst

Pittosporum tobira ‘Kansai Sunburst’ is looking lovely in the mid-winter garden. This Japanese selection emerges with brightly cream-edged leaves which age to green. This selection came to the US, via the former Asiatica Nursery, which brought so many wonderful Japanese selections to American gardeners.

This native of China, Japan, and Korea should mature around 10′ in height. Pittosporum tobira is prized for its spring-produced, intensely-fragrant small white flowers that smell like orange blossoms. We’ve had our plants in the ground since 2007, so they’ve passed the survival test of two winters with low temperatures in the single digits F. Winter hardiness is Zone 7b and warmer.

bloomin’ Ice n’ Roses

The Helleborus x gladorfensis hybrids, known as the “Ice n’ Roses” series have begun with the opening of Helleborus ‘Ice n’ Roses Barolo’. This is the earlies flowering and darkest clone in the series…just a shade darker than H. ‘Ice n’ Roses Red’. These are sterile hybrids derived from crossed of Helleborus niger with Helleborus x hybridus. Winter hardiness is Zone 5a-8b.

Helleborus x glandorfensis ‘Ice n’ Roses Barolo’

Artist’s Palette in Winter

Asarum hypogynum ‘Artist’s Palette’ is in full flower here at JLBG in late January. Despite being first published in 1915, this little-known species is very poorly represented in ex-situ plant collections worldwide. Our clone is a division from a wild plant we brought back from our 2008 botanical expedition to Taiwan. The foliage on this species is some of the largest in the entire genus. For us, Asarum hypogynum starts flowering in late summer and continues most of the winter. We are working to eventually be able to share this with other collectors. Hardiness is Zone 7b and warmer.

Bye Bye Borinda

We love busting horticultural myths, and here’s our latest. Borinda fungosa is another of the wonderful clumping bamboos from China, which, according to bamboo authorities, will not tolerate either our winter temperatures or our summer heat and humidity. Well, darn!

Excuse us for sharing this photo from late January, but here is our 2010 planting of a seed grown plant, and of course, it’s easy to see how poorly it’s growing. That said, we know that it will die to the ground at single digits F, and then re-sprout the following spring. The lesson…don’t believe everything you hear or read.

Winter Iris Parade

With a mild winter so far at JLBG, our numerous Iris unguicularis clones have been flowering beautifully. First is the clone Iris unguicularis ‘Francis Wolseley’ and then Iris unguicularis ‘Winter Echoes’. Colors in this species ranges from white to light blue to dark purple.

High on Loquats

We truly love loquats…both to grow and consume. I first met Eriobotrya japonica in 1976 on a walk around the NC State campus with the late Dr. JC Raulston. I was amazed to see a mature 30’+ specimen growing against one of the campus buildings. I was determined to grow one of our own, so in the mid 1990s, we planted our first specimen here at JLBG.

Loquats, a Chinese native member of the rose family, makes a lovely small tree with large, evergreen foliage that resembles a corrugated Magnolia grandiflora. Another exceptional feature is the fragrant white flowers that start to open around Christmas. These are followed by delicious orange fruit in early spring, when winter temperatures don’t drop below the mid-teens F. Loquat foliage is also brewed as a tea, in addition to its numerous medicinal benefits. We have always found loquats to be much more winter hardy than most of the literature indicates. Our oldest specimen planted in 1997, has never experienced any winter damage. Hardiness is Zone 7b and warmer.
