In flower this week is Fothergilla milleri ‘Redneck Nation’. Most people have probably never heard of Fothergilla milleri, since it was just described as a new species in 2020. When a DNA analysis of the genus was completed, it showed several diploid populations previously thought to be Fothergilla gardenii were actually a new, undescribed species. Immediately after being described, it was listed as a Globally imperilled species (G2 rank).
Currently, Fothergilla milleri, which grows in swampy bog forests, is known from only 6-20 populations: a few in Coastal Alabama, one in Georgia, and a few in the Florida panhandle. This Baldwin County clone was discovered by naturalist, Fred Nation. The species was named to honor Dr. Ron Miller.
We hope everyone has had a chance to check out the new 2023 Plant Delights catalog, now online. Our greenhouse are fully stocked with plants we hope will appeal to the gardeners in our audience….see photos below taken this week.
Our market has always been a bit different that other mainstream mail order nurseries, first because we grow and produce virtually all of our own offerings. That allows us better control over quality, trueness to name, and availability. Our on-line offerings are currently just over 1000 items, of which over 300 are Plant Delights/Juniper Level Botanic Garden introductions or exclusives.
Flowering now in the garden is the fabulous Fatsia japonica ‘Ripple Effect’. Although this isn’t currently on the market, we’re working diligently on propagation. Thanks to the US National Arboretum for sharing this amazing selection, which we hope to introduce in the next couple of years.
Just back from the Perennial Plant Association meeting in Lancaster, PA, held in person for the first time in three years. It was like a family reunion after such a long period of no contact, except via Zoom. Over 450 people from around the world showed up for the first year back.
The Perennial Plant Association is a professional organization for people involved in production, sales, trials, research, landscaping, or growing perennials. The annual meetings consist of a week of talks, tours, and a trade show. There are plenty of tour options, so attendees can select whether they are more interested in landscape design, retail, or production.
Aris Greenleaf is a large liner producer, who also has a trial garden. Sadly, non of the trial plants here had been planted more than a few months.
Cavano’s Nursery in nearby Maryland, was one of several top notch perennial growers we visited.
North Creek Nursery, a leading producer of native plant liners in PA, hosted the group for an amazing dinner
Owner Ed Snodgrass welcomed the group to his Emory Knoll Farms, an “off the grid” nursery that only produces plants for green roofs. 100% of their power is produced by solar panels on site.
For those unfamiliar with green roofs, shingles are replaced with plants, which help insulate the structure, while also reducing runoff.
What interested many on this tour, was their use of an outdoor version of a Stanley Steamer, for weed control. The manufacturer, Weedtechnics is out of Australia, but has a few US distributors.
Steam is applied too kill weeds as you would clean a carpet. The steam only penetrates the ground to 5 mm, but that’s enough to kill both the weed and weed seed, without bothering nearby plants. This is certainly a technology many of us on the tour will be investigating.
We visited the amazing Mt. Cuba Center in Delaware, a place I’ve had the pleasure of visiting several times over the last 30 years. The gardens have undergrown a dramatic facelift that made a great garden even better. It was great to catch the native Zigadenus glaberrimus in full flower by the lower pond.
The amazing Chanticleer Gardens and Longwood Gardens both hosted the group for two incredible dinners and a chance to stroll the grounds. At Chanticleer, we caught the water lotus (Nelumbo) in full flower, looking eerily like something from the Little Shop of Horrors.
Of course, we are all there to see the latest and greatest in new plants, and these gatherings never fail to show us something new we need to try. Below are the latest from the world of echinacea breeding.
Of course, in addition to the plants, these meetings are also about the people and the networking that these meetings afford. It was great to see two former JLBG’ers in attendance, Adrienne and Jon Roethling. Adrienne is now the Director of the Paul Ciener Garden in NC, and Jon heads up the grounds at Reynolda House and Gardens.
It was a lovely surprise to run into an old friend, plantsman Barry Yinger, who was in town, taking a break from his Sanseveria conservation work in Tanzania to visit his sister, and happened to be staying next door to the convention.
It’s always great to catch up with old friends, Nanci Allen (long time PPA director), and Allan Armitage (retired UGA professor). You never know who you’ll run into at these meetings. If you work in the field, check out the PPA, and perhaps we’ll see you at a future symposium.
This spring, Plant Delights introduced Zac Hill’s 2013 discovery of a new ruellia which he found in central Alabama. What we theorized might be a natural hybrid turned out to be a brand new species, as we were informed by botanists working on getting the plant published. We hope all native plant enthusiasts purchased this to both enjoy in their garden and for ex-situ (off site) conservation value. These are in full flower during the summer. Hardiness is unknown at this point, but we know it’s fine from Zone 7b – 8b, and most likely much further north.
Just over a month remains before the 2022 Southeastern Plant Symposium kicks off in Raleigh at the Sheraton Hotel, downtown. This joint venture between JLBG/Plant Delights and the JC Raulston Arboretum brings together the top horticultural speakers from around the world to regale attendees with tales of their favorite new plants. Each symposium rotates a focus on either on woody plants, perennials, or geophytes. The 2022 symposium is perennials focused.
The dates are Friday, June 10 and Saturday June 11. Both the JC Raulston Arboretum and Juniper Level Botanic Garden/Plant Delights will be open for visitors on the Thursday prior and the Sunday morning after the symposium.
A few of the amazing speakers include:
Leftherios Dariotis – If you’re a sports fan, you’ve heard the nickname “Greek Freak” applied to NBA star, Giannis Antetokounmpo. Well, Leftherios (aka: Liberto Dario) is to horticulture, what Giannis is to basketball…a true superstar. Leftherios will travel from his home in Greece to dazzle you with an array of little-known plants that thrive in hot, dry climates.
Dan Hinkley, founder of Heronswood and Windcliff, plant explorer extraordinaire, and recipient of the world’s top horticultural honors, will join us to share his latest botanical adventures and plants that have potential for our hot, humid climate. Dan bring a new perspective from having experienced 117 degrees F. in his Washington garden in 2021.
Patrick McMillan is a NC native, who spent two decades as a professor at Clemson. While there, he hosted the Emmy Award winning PBS show, Expeditions with Patrick McMillan, as well as directing the SC Botanical Garden. After a 1.5 year stint as Director of Heronswood, he has returned to his roots in NC, and joined the staff of JLBG. Patrick is widely recognized for his incredible botanical knowledge. His new book, Wildflowers of South Carolina will hit bookshelves soon.
Peter Zale is the Associate Director of Conservation, Plant Breeding and Collections at Pennsylvannia’s Longwood Gardens. Peter specializes in a number of plant groups that include hardy orchids and phlox. You can’t help but be amazed at Peter’s conservation and breeding work as well as his extensive knowledge of the natural world.
Plantsman Adam Black is known worldwide for his botanical exploits, primarily focused on the state of Texas. Adam has spent years traversing every corner of Texas, both re-discovering long lost plants and finding new ones. Adam’s horticultural background gives him a unique take on which Texas native plants will have great garden value for gardeners in the southeast. Adam has recently moved to NC to take a job as an Assistant Curator at the Bartlett Arboretum. We guarantee you’ll meet more new plants than you ever thought possible.
Kelly Norris is a true renaissance horticulturist. Growing up in a Midwest iris nursery propelled Kelly into the public horticultural arena. After a stint beefing up the collections at the Des Moines Botanic Garden, Kelly now splits his time between landscape design, writing, and extolling the virtues of new plants on QVC. Kelly is one of the new wave of great thinkers in our industry who understands the need for the fields of botany and horticulture to collaborate.
On Saturday, the pace picks up even more, with shorter, but intensively focused talks. The list of Saturday presenters include Mark Weathington, Director of the JC Raulston Arboretum will speak on his favorite new perennials. Ian Caton, founder of Wood Thrush Natives in Virginia will speak on Underused and Little-known Appalachian Natives. Hayes Jackson, Alabama Extension Agent and Director of The Longleaf Botanical Garden in Alabama will speak on Creating a Tropical Garden Feel in a Temperate Climate.
We are pleased to welcome Richard Hawke, Manager of the Perennial Trials at the Chicago Botanic Garden. Richard’s detailed cultivar evaluations are prized by gardeners throughout the country. Shannon Currey, Marketing Manager for Hoffman’s Nursery, will share her passion for sedges, while Adrienne Roethling, Director of the Paul Ciener Botanical Garden will discuss her favorite vines. Yours’ truly, Tony Avent, will share more than you ever thought possible about the genus Baptisia.
Did I mention the symposium includes the now world-famous rare plant auction, which has garnered International attention? The auction and symposium will be available both on-line and remote.
Mark and I truly hope you will join us for this incredible perennials-focused symposium, back in person for the first time in three years. The Symposium is an important fundraiser for both the JC Raulston Arboretum as well as the Juniper Level Botanic Garden Endowment. Here is the link to register for the Symposium. We’ll see you in June!
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.
One of many exciting new introductions for 2022 is Phlox divaricata ‘Blue Ribbons’ PPAF. This variegated version of our wonderful native woodland phlox was discovered here as a single sport in our garden by our plant taxonomist, Zac Hill. Instead of being all green, each leaf is edged with a wide creamy border and flushed with pink during the colder months. In early spring, the entire clumps are topped with sweetly fragrant blue flowers. We think Phlox ‘Blue Ribbons’ is an incredible design addition for the woodland garden. Hardiness is Zone 3-8. The new catalog, with this and many other amazing gems, goes on-line in 2 weeks!
Last year, we saw a listing for a new Mangave, M. ‘Purple Passion’ on the availability of a West Coast liner producer, so we ordered some to try. It was immediately evident when we unpacked the shipment, that the plants didn’t look anything like a mangave, nor did what we received match the image that the supplier had on their website.
As we dug deeper, we found that the supplier had misappropriated a mangave image from another wholesaler and was using it for the plant we purchased, desptie the two looking nothing alike. Once the image issue was remedied, we set out trying to track down the origin of this strange plant, which looked more like a steamrolled eucomis than a mangave.
The supplier sent us to their supposed source, who had never heard of the plant in question. For six months, we have chased down one lead after another, contacting all of the well-known plant breeders of these type of plants on the West Coast. All dead ends.
Examining the plant in our garden this summer, it occurred to us that the unusual leaf netting must have come from a beschorneria. Comparing the foliage netting of ‘Purple Passion’ to beschornerias in our garden yielded a perfect match, except for the leaf color. The only plant which could have been crossed with a beschorneria to give such leaf color is a manfreda. Hence, our conclusion that our plant is in fact a new bi-generic hybrid, x Beschfreda ‘Purple Passion’ (beschorneria x manfreda).
Since we don’t know which species of beschorneria was used, we are uncertain about potential winter hardiness, but with plants in the ground now, all we need to do is wait for cold weather. Below is a photo of the plant in the garden this week. If you happen to know more of the backstory of this fascinating plant, please let us know.
We’ve been growing the Chinese Arachnioides simulans, the similar spider fern, for over a decade, in which time, it’s proven a superb performer. Here’s a photo from the gardens this week. Finally, this spring, we got around to sowing spore, in the hope we can make this available soon though Plant Delights Nursery…fingers crossed for next year.
Back in the early 2000s, I printed out every exchange from the International Bulb Society email list that discussed the bulb genus, hymenocallis (spider lilies). Most conversations originated with Victor Lambou, who was obviously an authority on the genus. It’s now been years since the Bulb Society went defunct and I had lost track of Vic and his work. I, and others assumed that Victor had passed away and his plant collection had vanished, as is usually the case with keen specialty plant collectors, whose families don’t share the same passion or have an appreciation of the importance of their collections.
I was on the road visiting nurseries in late March, when I received a phone call that could best be described as horticulturally shocking. A friend from the American Iris Society was calling to share that they had been contacted to gauge their interest in the iris collection of a Florida plantsman, Victor Lambou, who was in declining health. “Had I ever heard of Vic”, they asked. That call set in motion a series of events that would culminate in a massive plant rescue this September.
Victor Lambou, 92, of Tallahassee, Florida (no relation to Curly Lambeau of the better-known Lambeau Field) is a well-known, retired Environmental Aquatic Biologist, who had a career with the EPA as a fish specialist. In his latter years, Victor became interested in native aquatic plants, primarily in the genus Iris and Hymenocallis. His career travels through swamps and bogs allowed him to locate and rescue several rare and significant plant species, as well as numerous variants within those species. His work in cultivating and later breeding these plants resulted in a botanically significant world class collection that is quite worthy of preservation.
Due to his advanced age, Victor had been unable to maintain his collection since 2017, and is now living in an assisted living facility. In August, after five months of working through the court system, the Florida Court system, with the approval of the trustee and Victor, granted us ownership of his entire plant collection.
The next step was a one-day scouting trip in late August to access what actually remained, the condition of the plants, and if a rescue was feasible. Not only were the plants still in great shape, but the project was much larger than I could possibly have imagined. The highlight, of course, was a chance to finally meet Victor in person and chat about his collection.
Victor’s plant collection consisted of approximately 2000 tubs of plants. Our visual rough estimate put the plant count to be between 30-40,000. Because of the aquatic nature of Victor’s plant collection, all plants were all grown in sealed-bottom tubs of mud, each weighing 60-100 lbs. Plants were meticulously arranged by block, row, and then position within the row. Victor’s last plant inventory in 2017, showed 617 unique plant taxa (taxa = genetically distinct individual). Were it not for Victor’s containerized system of growing plants aquatically, it’s doubtful that anything would have survived four years of neglect.
Victor’s list included 407 taxa of hymenocallis, 138 taxa of iris, and 44 taxa of crinum, and a few assorted other plant genera. To put Victor’s hymenocallis collection in perspective, the Botanic Gardens Conservation International (BGCI), which maintains the world’s only global database of living plant collections in botanic gardens, only lists 118 hymenocallis taxa preserved in collections worldwide. In other words, Victor had almost 3.4 times the worlds entire collection of hymenocallis is his backyard.
My initial assessment was followed by a full-fledged rescue in early September. JLBG staff members Amanda Wilkins (garden curator), and Zac Hill (plant records/taxonomist), and JC Raulston Arboretum director, Mark Weathington joined me for the 9 hour drive to Tallahassee, stopping briefly to pick up a 15′ U-Haul once we arrived in Florida.
We also extended invitations to 25 gardens/plant collectors. Of that group, 10 were able to participate. The botanical gardens/staff who participated and will be housing plants from Victor’s collections include:
Hayes Jackson Longleaf Botanical Garden, AL
Pat Lynch Bok Tower Gardens, FL
Mark Weathington JC Raulston Arboretum, NC
Andy Cabe Riverbanks Botanical Garden, SC
Todd Lasseigne Bellingrath Gardens, AL
Once we began the site rescue, we discovered that approximately 10% of the collections were no longer alive, leaving approximately 555 living taxa. Our rescue efforts were not focused on named cultivars of plant species that were already established in commerce (approximately 93 taxa), or un-identified taxa (approximately 24 taxa), or open pollinated seedlings (approximately 10 taxa). Consequently, rescue efforts were aimed at the 428 most important taxa.
None of the tubs were labeled, but thankfully Victor had extensive bed maps, which the trustee made available. Without these, the plant collection would be botanically worthless. Two full days were spent extracting plants from the muddy tubs. We tried an array of extraction methods, but finally found it best to employ the back-breaking task of upturning each container and sift through the muck to extract the plants.
Small quantities of some varieties were labeled and stored in Ziploc bags, while larger quantities were stored in community pots.
Not only were the plants interesting, but Victor also had one of the larger collections of Lubber grasshoppers that I’ve ever encountered. These voracious critters seem to love the plants as much as we did. Of course, these protein filled insects reduced the need for frequent snack breaks. I’d always heard the slogan that Virginia is For Lovers, but little did I know that Florida is for Lubbers.
The rescue became slower and more challenging, when unbeknownst to us, Tropical Storm Mindy had formed virtually on top of us, during our second day of rescue. Consequently, there wasn’t a dry eye…or anything else in the place when we finished and loaded the U-Haul for the return trip.
Rescue team/plant relocations
The next phase of the rescue operation is scheduled for Sept 20, 2021. This will involve the Louisiana Iris Society Historical Preservation Group. This subgroup of the American Iris Society has species conservation stewards who will each house a replicated collection of Victor’s iris. Of the 138 Iris taxa in Victor’s collection, there are 24 different taxa of the southeast native Iris hexagona. Currently, the Iris Preservation Network only has 6 taxa, so these are extremely valuable for conservation purposes. Juniper Level Botanic Garden also has a duplicate collection of Victor’s iris.
When the final phase of the rescue is complete, Victor’s plants will have been distributed to 9 botanical gardens and 5 private collectors gardens. We have instructed these gardens to share with other gardens in appropriate climatic zones, so we feel confident that Victor’s collections will continue to be shared and conserved even more widely.
JLBG spent 392 labor hours on the rescue, including 76 hours on site at Victor’s garden. Our team from Juniper Level Botanic Garden was able to rescue 291 taxa. Taxa that were too tender to live outdoors in our Zone 7b, were sent to gardens in warmer climates. The total number of plants rescued and now housed at JLBG is 5000 plants. This does not include the additional collections which are housed at our sister institution, the JC Raulston Arboretum.
We were able to rescue 19 hymenocallis that Victor has selected and named, along with 3 of his named/selected Iris. Victor’s collection consisted of over 123 of his hymenocallis hybrids which are still in need of evaluation. These were rescued and have been planted in our research area here at JLBG. Any of these that prove to be distinct and exceptional will be propagated and introduced to the horticultural world, via our nursery division, Plant Delights Nursery.
Before the Lambou rescue, JLBG already grew 42 taxa of hymenocallis, which number has now swelled to 263, making it almost certainly the most extensive collection of hymenocallis taxa in the world.
We hope that this will be a model for the future for Botanical Gardens to collaborate to preserve these vitally important ex-situ private plant collections.
Late summer and fall are a great time to enjoy the plumes of our US native ornamental grass, Panicum virgatum. Here are two photos from the garden this week. The first is one of my favorites, the giant Panicum ‘Cloud 9’…an introduction from Maryland’s defunct Bluemount Nursery. Below this is a new dwarf, blue-foliage introduction for 2022, from Walters Gardens, Panicum ‘Niagara Falls’. It has proven exceptional in our trials and will appear in the January Plant Delights Nursery catalog.
We have long enjoyed the winter-flowering, evergreen Clematis armandii, but had no idea the variability that existed until we acquired this new form from China in 2012. Unlike the more commonly known Clematis armandii var. armandii, which has 4 petals per flower, the subspecies hefengensis from Southwest Hubei Province in China has six petals. We have given this exceptional clone the cultivar name Clematis ‘Six Shooter’. We haven’t started propagating this yet, but are thinking about doing so. Would anyone be interested?
Plants in the genus asarum are small but exquisite, deer-resistant woodland perennials that thrive in moist but well-drained conditions with light shade. Many asarum species are evergreen and make a great ground cover in the woodland garden. Here are some images of asarum in the garden this morning.
Asarum are one of our specialty collections at Juniper Level Botanic Garden, with 86 species and 529 unique clones. Join Tony in the gardens during this Gardening Unplugged video garden chat about wild gingers.
The flower color of asarums are usually burgundy or purple, but we are always on the look out for variants. Towards the end of the video Tony shows a yellow flowered form, Asarum ichangense ‘Ichang Lemon’, which we hope to have available for 2021. We do have another yellow flowered form we are offering for the first time this year, Asarum ‘Tama Rasya’.
For 2020, we’ve added over 90+ new plants in the catalog, with more than 50 being Plant Delights Nursery exclusives, thanks to the incredible work of our staff who scour the world, in addition to our own selecting and breeding, to bring you these amazing new plants. View the digital version here!
As we allude to on the cover, keeping up with the plant name change carousel is a feat itself. Continual advances in DNA are revealing relationships we never dreamed possible. When a name change is supported by good research and conclusions, we include both names for several years, since the purpose of nomenclature is about facilitating communications. We apologize for what often seems like confusing name changing, but really, we have more nomenclatural clarity now than ever.
Here are a couple of favorites from our trials that will be included in our new catalog to be launched January 1. These are the Bedazzled series of Phlox, created by plantsman Hans Hansen, using our native Phlox bifida. Last year, these started flowering for us in late January and continued into April. In the ground, our clumps are only 4″ tall and 2′ wide. These are much more dense that typical Phlox bifida, and much more compact than Phlox subulata. Even before flowering, the evergreen foliage is pristine all winter. The first is ‘Bedazzled Lavender’ and the second is ‘Bedazzled Pink’.
