Many gardeners tend to ignore the narrow leaf Trillium lancifolium in favor of the larger, more impressive species, but we think this smaller toadshade is quite garden worthy. Below are two clones we’ve named and introduced in the past. One is in full flower here at JLBG, and the other is right behind in mid-March. Hardiness is Zone 6a-9b.
Those of us who have studied trilliums extensively in the wild, feel that all Trillium lancifolium are not created equal. In other words, what is currently known as Trillium lancifolium is most likely 2-3 different species. These are botanically known as cryptic species, since they are hiding in plain site. Advances in DNA now allows researchers to confirm field observations, so don’t be surprised if you see more new trillium species being named from this complex.
The first image below is Trillium lancifolium ‘Lancelot’, a selection from North Florida that forms dense clumps, compared all of the other plants from this population, which grew as solitary stems. The flowers are also butterscotch instead of the typical purple.
Trillium ‘Black Panther’ is a JLBG selection from a cross of genetics from a Florida population with a Tennessee collection. It also forms dense clumps.
We’ve just wrapped up the 2022 Southeastern Plant Symposium in Raleigh, and were thrilled to have nearly 200 attendees. It was great to be back in person after two years of remote Zooming. The symposium is co-sponsored by the JC Raulston Arboretum and Juniper Level Botanic Garden, with all proceeds split between the two institutions (JCRA operations and the JLBG endowment).
Attendees were entertained and enlightened by fourteen of the top horticultural authorities in the country/world. This years symposium was focused on perennials, 2023 will be focused on woody plants (trees/shrubs), and 2024 will focus on geophytes (bulbs, tubers, etc.) as part of our three year rotation.
We hope you’ll join us for 2023, and mark June 9, 10 on your calendar. Not only are the speakers excellent, but the symposium includes a rare plant auction, which this year, offered over 430 plants, most of which aren’t available anywhere else in the world.
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!
We’re just back from a four-day plant roundup of donations (from some of the regions top plantsmen/women) to the Southeastern Plant Symposium rare plant auction this weekend. So far, we have over 350 plants, many of which aren’t available anywhere else in the world. The Symposium, which is a fundraising event for the JC Raulston Arboretum and the JLBG Endowment @ NC State, is virtual this year, and begins Saturday morning, June 12. The on-line auction has already begun, and runs through Saturday afternoon. If you’d like to check out the auction treasures, you can do so here. Plants which are 1 gallon size and smaller may be shipped, but large sizes are only available to be picked up. You do not need to sign up for the Symposium to participate in the auction, but we’d encourage you to join us for some truly amazing speakers. You can register for the talks here.
