"Around the World in 80 Plants: An Edimental Perennial Adventure"
Stephen Barstow, Author

"Extreme Salad Man," Stephen Barstow, author of Around the World in 80 Plants: An Edible Perennial Vegetable Adventure for Temperate Climates will share a lifetime of adventure planting and sampling 6,000 different vegetables from around the world. Moving from the United Kingdom to Norway in 1981 as a young vegetarian and naturalist to work as an oceanographer led him to develop a forest garden and one of the largest collections of edible plants anywhere. He'll lead us on an inspiring global adventure introducing us to a selection of his top climate friendly and nutritious perennial vegetables which double as ornamentals (he invented the terms edimentals and edi-ento-mentals for these plants, the latter also being great pollinator plants).

Magnolia macrophylla var. ashei 56801H

"The U.S. National Arboretum: Helping Improve the Gardens of Today and Tomorrow"
Kevin Conrad, U.S. National Arboretum

Ornamental horticulture in the United States depends on a diverse and dynamic array of woody landscape plant material to address pests and disease issues, provide stress tolerant plant material for sustainable landscapes, and meet changing consumer needs and trends. Acquisition and curation of woody landscape plant germplasm is even more critical given the diminished genetic diversity of planted landscapes. The National Arboretum is tasked with building a comprehensive collection of documented woody landscape plant germplasm that is available to the national and international nursery industry and the public garden and research communities to be used to create improved ornamental plant varieties. Kevin's talk will focus on the role the arboretum germplasm program plays in conservation and supporting this effort.

Monarda menthifolia

"A Second Look at Less Common and Underappreciated Natives"
Aaron Floden, Missouri Botanical Garden

Plants native to North America have historically received greater appreciation outside of the country. For some time, the native plant movement has brought more common and more showy species to the forefront of horticulture. Aaron hopes to introduce you to some new natives, some of which are still to be described, and also get reacquainted with selections of more commonly encountered natives that deserve a little bit more attention. We'll take a look at Blephilia, Monarda, Trautvetteria, and much more.

Long Border in flower at Great Dixter

"Designing with Plants the Great Dixter Way"
Fergus Garrett, Great Dixter

Great Dixter, "a place of pilgrimage for horticulturists from across the world," is expertly cared for by Fergus Garrett. In this presentation, Fergus will discuss the sense of place, connecting to the countryside, self-sowers, and informality, as well as foliage texture and shape contrast. Fergus will talk about plants acting as catalysts to each other, punctuation, repetition, and rhythm in a border. He'll illustrate the experiments with color in the garden as well as touch on layered planting for a long season.

"My Journey with Plants, Plant Breeding, Evaluation, and Gardening"
Hans Hansen, Walters Gardens

Hans, one of the world's leading perennial plant breeders, will discuss his personal involvement with perennials and plant development over the years focusing on Epimedium, Hosta, Hibiscus, and ×Mangave as well as his personal gardening style and interaction with people that influenced improvement in these genera.

Hydranea arborescens cultivars

"Plant Breeding at the Mountain Crop Improvement Lab"
Irene Palmer, Mountain Crop Improvement Lab, NC State University

Take a virtual trip to the Mountain Crop Improvement Lab (MCIL), where NC State faculty, staff, graduate students, and interns work together to develop a greater understanding of bioenergy and nursery crop breeding and improvement. Our diverse program works in over 60 genera and uses foundational and emerging technologies to develop and trial value-added, problem-solving landscape and bioenergy plants. The pathway from breeding objectives to commercial introduction will be discussed as well as a quick overview of some newer plant introductions and ongoing research at the MCIL.

Cypripedium parviflorum var. pubescens

"Native Orchid Conservation Efforts at Longwood Gardens"
Peter Zale, Ph.D., Longwood Gardens

Successful orchid conservation requires a multidisciplinary approach that supports in situ and ex situ conservation. Public gardens are expected to play a key role in supporting these efforts. Longwood Gardens initiated a native orchid conservation program in 2015 that focuses on horticultural aspects of ex situ orchid conservation including seed propagation, seedling establishment, and collections development that is balanced with in situ restoration, population assessments of rare species, and field work to catalogue previously unknown orchid occurrences. Peter will present on the development, successful outcomes, and future aspirations of the program to date.
