Seven of the world’s top botanical and horticultural experts will speak at the 2021 Southeastern Plant Symposium and Rare Plant Auction, according to event organizers Mark Weathington, Director of JC Raulston Arboretum at NC State University, and Tony Avent, Founder of Juniper Level Botanic Garden and Plant Delights Nursery.

Southeastern Plant Symposium will be online worldwide and available to registered attendees on Saturday, June 12, from 9am-5pm. The registration fee is $75. This live presentation will be recorded and made available to all registrants.

The Rare Plant Auction is free and opens online to attendees and the public on June 3, 2021 at 3pm, ending on June 12 at 5pm

(All times are Eastern Daylight Time USA)

Featured speakers include:

  • Fergus Garrett, one of the greatest garden designers and garden makers in the world, CEO and Head Gardener, Great Dixter House and Gardens, United Kingdom.
  • Stephen Barstow, Extreme Salad Man, a global expert on ornamental edibles, inventor of the term edimentals, author of Around the World in 80 Plants, leader of the Norwegian Seed Saver organization.
  • Peter Zale, Ph.D., Associate Director, Conservation, Plant Breeding and Collections, Longwood Gardens, PA, USA.
  • Kevin Conrad, Botanist, US National Arboretum, Woody Landscape Plant Germplasm Repository, National Plant Germplasm System, Beltsville, MD, USA.
  • Irene Palmer, Research Specialist with Tom Ranney, Ph.D., North Carolina State University, experienced in a wide range of plant breeding with a focus on hydrangeas, camellias, crepe myrtles, azaleas, and more, NC, USA.
  • Aaron Floden, Ph.D., Botanist, Missouri Botanic Garden, a world expert on plants with a focus on native American flora, MO, USA.
  • Hans Hansen, Director, New Plant Development, Walters Gardens, Zeeland, MI, USA.

“The symposium is for horticulturalists, botanists, garden and nursery staff, serious gardeners, and those who want to learn more about plants,” said Weathington. “The presentations will be filled with information and beautiful visuals. Attendees can ask questions during the presentations.”

“The Rare Plant Auction will feature a collection of plants not found anywhere else in the world,” said Avent. “Even the most rabid plant collector will find many things in the auction they’ve never seen or heard of before. There is no other source for many of these plants. People may have searched for years and never found these plants — it is that rare.”

“This is an amazing opportunity to hear many top experts in a single event,” said Weathington. “One of our speakers is Fergus Garrett, CEO and Head Gardner at Great Dixter House & Gardens in the United Kingdom. Fergus is one of the best garden designers and garden makers in the world and will talk about the importance of color, foliage, texture, repetition, structure, experimentation, as well as informality and movement in putting plants together.”

“Known as the Extreme Salad Man, Stephen Barstow is a world authority on ornamental edibles and invented the term edimentals,” added Avent. “Barstow authored the book Around the World in 80 Plants and will make you look at your garden differently – thinking about the ornamentals you can grow, enjoy, cook, and eat.”

Said Weathington:

“Peter Zale of Longwood Gardens in Pennsylvania is a true genius. He is destined to have a huge impact on both the science of botany and the art of horticulture. His work with orchids has been significant to JC Raulston Arboretum, as he has grown out most of the JC Raulston Arboretum Asian orchid seed collections for us.

“Kevin Conrad, a botanist with the US National Arboretum and USDA in Maryland, is responsible for the conservation of over 5,000 taxa of woody landscape plants and the development of the Woody Landscape Plant Germplasm Repository. Their focus is long-term preservation and technology transfer for use in research and crop improvement. Kevin works closely with botanic gardens to help conserve genetics. JC Raulston Arboretum holds two national collections — redbuds and magnolia.

“Irene Palmer is a North Carolina State University researcher working with Tom Ranney, Ph.D., on breeding a wide variety of plants. Irene also focuses on hydrangeas, camellias, crepe myrtles, azaleas, and other southeastern garden favorites to help set new standards.

“Aaron Floden, a botanist for the Missouri Botanic Garden, focuses heavily on native American flora. He is also a world expert on other plants such as Polygonatum and its relatives. Much like Peter Zale, Aaron is a keen scientist, a field researcher, and a great gardener. No matter how often I hear him speak, I am always astounded by something new — often something growing in my own state.”

Added Avent:  “Hans Hansen, Director of New Plant Development at Walters Gardens in Michigan, is the top perennial breeder in the world today in my opinion. His plants are found in almost every garden center in the country. Hans breeds for Proven Winners. So, pretty much every Proven Winners perennial grown in the last decade was probably his breeding.”

Proceeds from the Southeastern Plant Symposium and Rare Plant Auction benefit the endowments of Juniper Level Botanic Garden and JC Raulston Arboretum at NC State University.

“We have parallel missions and visions of what gardens and plants are for,” said Weathington. “Plants are critical assets. We are growing them and conserving them for science and for the benefit of all people. In our home state, ornamental plants are one of the biggest agricultural products.”

Fundraising efforts for Juniper Level Botanic Garden (tax ID 56-6000756) and JC Raulston Arboretum (tax ID 56-6049304) operate under the auspices of The Endowment Fund of North Carolina State University, a 501(c)3 non-profit. Donors receive official receipts for contributions to the fund.
