Flaming Torch

In flower this week is the amazing ginger lily, Hedychium ‘Flaming Torch’…our 1999 introduction, with its’ fragrant peachy flowers is still looking great! This is another of those plants that never sold particularly well, so we haven’t offered it since 2016. Winter hardiness is Zone 7b and warmer.

Crinum Time Again

Re-appropriating a line from the late Buck Owens, it’s crinum time again. Crinum lilies begin their flowering season in our climate around April 1 (frost permitting). Some bloom for a short number of weeks, while other rebloom for months. Depending on the genetics, some crinum hybrids start flowering in spring, some in summer, and others in fall, and a few flower during the entire growing season.

Crinum ‘High on Peppermint’ is one of our newer named hybrids, which starts flowering for us around June 1, and hasn’t stopped yet.

Crinum ‘High on Peppermint’

Crinum ‘Superliscious’ is another of our new hybrids that starts flowering July 1, and has yet to stop. Now that our evaluation process is complete, we’ll start the propagation process.

Crinum ‘Superliscious’

Crinum ‘Southern Star’ is an incredible hybrid from the late Roger Berry, entrusted to us to propagate and make available. That’s a tall order since it’s one of the slowest offsetting crinum lilies we’ve ever grown. Crinum ‘Southern Star’ is a hybrid with the virtually ungrowable, yellow-flowered Crinum luteolum, which hails from Southern Australia. For us, Crinum ‘Southern Star’ doesn’t start it’s floral display until August 1.

Suckin’ Daphnes

I’ve been surprised to see the black swallowtails regularly enjoying the nectar of the summer-flowering daphnes…in this case, Daphne x napolitana ‘Bramdream’. Our plants are thriving, growing in our full sun rock garden.

Eau de Chocolate

One of the most amazing summer perennials we grow is the native Berlandiera pumila ‘Chocoholic’. It is unfathomable to us, why this isn’t grown in every full sun garden where it’s winter hardy. The flowers, which smell like milk chocolate, top the 3′ tall clump nonstop from May until October. In the wild, Berlandiera pumila can be found from NC south to Texas, so its drought tolerance is excellent. We rate this as Zone 7a to 9b, but that’s only because we don’t have feedback from folks in colder zones yet. Please let us know is you have this survive temperatures lower than 0 degrees F without snow cover!

Nectar tubes

We always look forward to late June with the patches of Sinningia tubiflora burst into flower. This rhizomatous perennial, first cousin to African Violets’, is rock hardy to 0 degrees F. This South American native (Argentina, Uruguay, and Paraguay) forms a dense deciduous groundcover, topped with these long-tubbed, honeysuckle-fragranced flowers that attract nocturnal moths with a really long proboscis.

For Crinum Out Loud

Our OCD is on full display with many of our plant collections including the summer-flowering Crinum lilies. Our collections here at JLBG have now topped 400 crinum taxa. In addition to collecting the best plants from other breeders, we have also been making a few of our own selected hybrids. Below are a few photos of plants we have recently selected and named. None of these are available yet, and most will still be a few years away, while we build up enough stock to share.

If you’ve never grown crinums (first cousin of hippeastrum), they form huge bulbs, and thrive in full sun in average to moist soils.

Around the world with 130 Styrax

We’ve had a longstanding love affair with the genus styrax, thanks to their amazing spring display of fragrant white bell-like flowers. Of the 130 recognized species, we have so far tried 22, of which 9 remain alive.

The first featured below is Styrax japonicus ‘Evening Light’. This amazing, black-foliage form of the typical green-leaf Styrax japonicus appeared as a seedling in Holland at the nursery of Henny Kolster. When I first saw the photo, I assumed it to have been “photoshopped”, but after growing it for several years here at JLBG, the foliage is indeed jet black. This is one of the most stunning small trees in our collection.

Styrax japonicus ‘Evening Light’

Styrax formosanus, which hails from Taiwan (Formosa) is undoubtedly the most floriferous species we’ve encounterd. Here is our garden plant this spring. For us, this generally tops out at 15′ to 20′ tall.

Styrax formosanus

Styrax americanus (Illinois south to Florida) is one of only four native US styrax species. Usually topping out around 10′ tall, this form introduced by Woodlanders Nursery has foliage with a lovely blue cast.

Styrax americanus var. pulverulentus ‘Baby Blue’

Oh, Daphne

My visit to Crete in 2010 was eye-opening when I observed that most native daphnes of the region grew in full sun among rock, in the driest conditions imaginable. That prompted us to re-try many of the daphnes that we’d killed years earlier…obviously, with too much kindness. Now, all of our daphnes are planted in baking sun in our crevice garden, or similar rock garden conditions. Here are a few photos at JLBG from early April.

The first is the Mediterranean native, Daphne collina, which most authorities now subsume under Daphne sericea. All daphne pictured below should be hardy from Zone 6a – 8b.

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.

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.

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.

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.

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.

Perfume of the Princess

Quite a few really smart horticulturists told us we didn’t have a chance of succeeding with Daphne ‘Perfume Princess’ in our climate. We’ll, we’re almost 2 years in the ground with this New Zealand hybrid of Daphne bholua x Daphne odora. It’s already full of flowers, where it’s thriving in our crevice garden. In the sense of full disclosure, we’ve never been able to keep the Daphne bholua parent alive. Hardiness is Zone 7b and warmer to at least Zone 8b.

Cantab-ulous

In full flower now at JLBG is Mahonia x lindsayae ‘Cantab’, a hybrid of Mahonia japonica and the virtually unknown Mahonia siamensis. The intensely sweet fragrance is truly intoxicating…the strongest in the genus Mahonia. Sadly, you’ll rarely find this available for sale, since it’s somewhat gangly form doesn’t curry favor with most nursery growers. Winter hardiness is Zone 7b and warmer.

The Osmanthus continue

The fragrance of the fall-flowering osmanthus continues. First, we saw good rebloom on Osmanthus fragrans ‘Tianxiang Taige’. This amazing cultivar has the largest flowers of any of the selections of this species.

Osmanthus fragrans ‘Tianxiang Taige’

The overpoweringly sweet fragrance of Osmanthus heterophyllus ‘Kaori Hime’ has been hard to miss over the last couple of weeks. Despite having tiny leaves, this is not a dwarf. Our 8-year old garden plant is 6′ tall x 7′ wide.

Osmanthus heterophyllus ‘Kaori Hime’

The Fragrance of Fall

Perfuming the garden this week are the amazing Osmanthus fragrans. This Chinese native evergreen shrub is unquestionably the most fragrant flowering plant in the garden. When the clusters of small flowers open early October, they emit a sweet fragrance that can easily waft for 200 feet. While we have nine clones in the gardens at JLBG, our oldest/largest two are Osmanthus fragrans ‘Conger Yellow’ (yellow flower) and ‘Aurantiacus’ (orange flower)…both pictured below.

Our sister institution, the JC Raulston Arboretum probably has the largest collection in the country of these amazing plants. For those old enough to remember, Osmanthus fragrans was a personal favorite of the late Dr. JC Raulston. If you are looking to purchase plants and can’t find them locally, our friend Ted Stephens, who runs a SC mail order nursery certainly has the largest offering in the country of these amazing plants.

Old Fashioned, but not out of Fashion

Hemerocallis ‘Autumn Daffodil’ was introduced in 1949, but remains one of the most incredible daylilies we grow here at JLBG. The 3′ tall, branched, sturdy, upright stems are topped with an abundance of amazing highly fragrant yellow flowers starting in July.

Shaking up Saxatile

For two decades, we’ve grown the amazing Chinese jack-in-the-pulpit, Arisaema saxatile with its delightful lemon-fragranced flowers. The most frustrating part was its slow offsetting nature, which meant we rarely had any to share.

Arisaema saxatile

Eighteen months ago, we dug our main clump and moved most of it from a well-shaded site to a location that would get a couple of hours of afternoon sun. To our surprise, it loved the new site, where this summer, it produced two large seed heads which will be harvested shortly. This is the first sign of seed in 20 years, so hopefully in a few years, we have some good numbers to share.

Pick Pink Pockets

Sinningia ‘Pink Pockets’ was a Plant Delights/JLBG introduction in 2011…a hardy gesneriad that had thrived in our in ground trials. Here it is this week, planted in 2005 and still performing superbly in part sun. We love plants that stand the test of time in the garden.

Goin tubing in the garden

We’ve got a different take on going tubing. For us, tubing is something we do, starting in mid-June each summer, when we sit and enjoy our patch of Sinningia tubiflora. This amazing South American (Argentina, Uruguay, and Paraguay) gesneriad (African violet cousin) forms masses of underground potato-like tubers, which produce these amazing stalks of sweetly fragrant flowers for months each summer. These are reportedly pollinated by sphinx months. Sinningia tubiflora is insanely drought resistant and so easy to grow if given enough sun. Since it forms a large mass, don’t plant it near smaller, less-aggressive neighbors.

Kale for Life

Blooming now in the crevice garden is one of our favorite edimentals. If you haven’t heard this word before, it’s the new combo term for edible ornamentals. Crambe maritima, known as sea kale, is a plant we first grew for its fragrant flowers, only to find it incredibly tasty, both fresh and cooked. We are constantly grabbing a leaf for a garden snack. Best of all, Crambe maritima is a perennial that doesn’t need to replanted yearly. We can’t imagine why every lover of kale doesn’t grow this. Dry full baking sun is all that’s required.

Crambe maritima

Winter Bridal Bouquet

Flowering this week is our selection of Magnolia floribunda ‘Bridal Bouquet’. When we visited Yunnan, China in 1996, we were able to return with three seed of Magnolia floribunda, a species which seemed completely absent from American horticulture. The resulting seedlings were planted into the garden, where two promptly died during the first winter. Thankfully, one survived and is still thriving today 25 years later.

Magnolia floribunda ‘Bridal Bouquet’ forms an upright, somewhat open evergreen that sometimes starts flowering as early as mid-January. This year, thanks to our consistent cold, it waited until early March to start its floral show. The flowers have a distinctive and fascinating fragrance that we find unique among our magnolia collection. We have shared cuttings with several woody plant nurseries and donated plants to a few rare plant auctions in the hopes of getting this more widely cultivated.

Tubing! Hummers! Summer!

The genus Sinningia is a South American gesneriad (African violet and gloxinia relative). Hummingbirds and butterflies just love the tubular flowers of Sinningia, and several species including Sinningia tubiflora, are quite fragrant.

Sinningia tubiflora

Sinningia flowers come in a wide array of colors from white, to yellow, pink, red and all shades in between. Sinningia species are drought-tolerant and heat loving…perfect for hummers and the southern garden.
We hope you will join us in our excitement over the wonderful perennial sinningia.

Sinningia ‘Cherries Jubilee’

Hymen Flowers

Hymen flowers (aka Hymenocallis) are still going, as the Northern Mexican species now perfume the garden. The genus begins flowering in spring, and if you grow a wide range of species, you can have flowers until late summer/early fall. Here’s a photo we recently took of Hymenocallis pimana in the garden.  While many hymenocallis prefer very moist soils, we grow this in a dry bed with agaves and cactus.  Starting in early evening, the flowers emit a honeysuckle-like fragrant to lure evening moths for reproductive activities. While we also like the more commonly sold Dutch hybrids, which are actually intergeneric crosses with the South American Ismene, we think the North American native species are far superior as garden plants, so we’ve always wondered why these don’t sell nearly as well as they should. 

Crinum ‘Improved Peachblow’

Crinum Improved Peachblow

Early June is an amazing time for crinum lilies in the gardens here at Juniper Level and here’s one of our favorites, photographed yesterday. ¬†Crinum ‘Improved Peachblow‘ is simply amazing…great flower form, sturdy stems, pink buds that open white, and a fragrance that’ll make a honeysuckle jealous. ¬†Crinum lilies are very easy to grow, but flower best in a moist, sunny location.

Sweet box begin sweet

Sarcococca hookeriana v. humilis purple stem in flower closeup

One of the great winter-flowering evergreen perennials is in full flower now.  Sarcococca hookeriana var. humilis, aka sweet box is a fascinating boxwood relative that forms a dense groundcover in shade.  What make sweet box special are the intensely fragrant flowers toward the end of winter.  All sarcococca are similar in form and flowering, varying mainly in height and fruit color.

Photos from the winter garden

Erythronium mesochorum A1AR-037b in flower

The native midwestern trout lily, Erythronium mesochorum showed it’s lovely face for the first time this week.  We sowed lots of seed last year, so hopefully we’ll have enough to share in a couple more years.

 

Helleborus niger Jesko forming seed

Even after the early flowers of the Christmas rose, Helleborus niger, finish, the lovely green petals and developing seed pods are quite attractive.

Iris unguicularis v. cretensis Katsifu Gorge flower

The Iris unguicularis have been amazing this winter.  This is our collection from Crete, where they grew in large grass-like masses.  Although this clone isn’t as floriferous as some we grow, the intensity of the color is quite special, and like all of the forms from Crete, the foliage is quite short.  We may have enough of this for a 2017 introduction.

Pachysandra procumbens Angola in flower

For the first time in several years, we are able to share our superb collection of  the native, evergreen Pachysandra procumbens ‘Angola’, that we collected near Angola prison.  This is the earliest, most vigorous, and most fragrant flowering form of this superb native that we’ve ever encountered.

 

Silene virginica Jackson Valentine winter rosette

 

Not only is Silene virginiana ‘Jackson Valentine’ superb in flowers, but it’s also pretty nice with its purple winter foliage.

Hosta ‘Sugar and Spice’

Hosta Sugar and Spice in flower2

We’ve been enjoying the late-flowering hostas over the last few weeks, with many just beginning.  One of our favorites is Hosta ‘Sugar and Spice’…a stunning sport of Hosta ‘Invincible’ with fragrant flowers and variegated foliage.  We put this as one of the best performing hostas we’ve ever grown..great foliage, great flowers, and great vigor in the garden.

Crinum lilies in the garden

Crinum x baconii Maurine Spinks5

 

This has been an amazing summer for crinum lilies at Juniper Level.  These mostly African species and their hybrids are wonderfully fragrant, hard-to-kill bulbs for the sunny garden.  Above is Crinum x baconii ‘Maureen Spinks’…one of the showiest summer-flowering hybrids.Crinum x digweedii Stars and Stripes5

 

Another of the milk and wine striped crinum lilies is Crinum x digweedii ‘Stars and Stripes’…here’s a recent photo from the garden.  It just oozes with fragrance!Crinum Rose Parade5If rosy pink is your thing, Crinum ‘Rose Parade’ is looking quite nice in the garden.  Crinum winter hardiness ranges from Zone 6 to Zone 8, depending on the species used in the cross.  You’ll find the hardiness zones for each in our on-line catalog, where we offer 40 varieties…probably one of the largest selections you’ll find.  Enjoy, and have a great weekend in the garden!

 

30′ tall Flowering Agave – a pollinators dream

Agave Grey Gator in full flower at top with ladderIt’s been absolutely amazing to watch the swarm of honeybees, ants, and hummingbirds feeding on our giant 30′ tall flowering agave.  Here’s an updated photo of the blessed event from yesterday.  This weekend’s final summer open house is the last chance to see it in person.

Here’s our research staff getting the giant ladder in place for breeding as the giant Agave salmiana x asperrima begins to open. Agave Grey Gator flowers with Jeremy on ladderAnd here’s Jeremy, who heads up our Research Division, gathering pollen and making crosses.  Breeding agaves is a little different from breeding daylilies, iris, and hostas. We hope you’ll join us during our summer open nursery and garden to see this monster in person.

 

Magnolia lotungensis flowering at JLBG

Parakmeria lotungensis flower

Here are photos of our lovely specimen of Magnolia (Parakmeria) lotungensis that flowered extremely well this year.  This evergreen magnolia is one of our favorites and has never shown a sign of winter damage here.  Fingers crossed for good seed set.

Arrangements to perfume the garden

Helicodiceros muscivorus arrangementI was recently looking for some flowers to put in a vase for our patio and got thinking…what would you use if your dinner guests were the type of people you wanted to eat and leave…quickly.  The answer was right before me…Pig Butt Arum, Helicodiceros muscivorus.  So, here’s my creation…also perfect if your child has a “favorite” teacher who they want to be sure remembers them over summer vacation.

 

 

Dianthus ‘Feurehexe’ (Firewitch)

Dianthus Feurhexe8

Here’s a shot of our patch of Dianthus ‘Feurehexe‘ in the garden…such an amazing display of insanely fragrant flowers…smells like spicy chocolate to me.  Good drainage and bright sun are the key to success, so their perfect for a rock garden.

Cora Stubbs Peony

Paeonia Coral Stubbs single flower7

The peonies were insanely beautiful this weekend for open house.  Here’s one of the stars, Paeonia ‘Cora Stubbs’…great sturdy stems and huge, fragrant flowers. We only offer peonies that we’ve trialed here at Juniper Level Botanic Garden for heat tolerance, great flowering, and good stem sturdiness.
