Keeping Seeds: Food, Ancestry, and Cultural Recovery

Chris Bolden-Newsome and Owen Taylor

Cultural recovery is at the center of the seed keeping work at Truelove Seeds.

9:45 am
Out with Offensive Plant Names

Jaime Morin Frye

Most garden visitors connect to plants through common names rather than their more technical botanical nomenclature. Yet, many of these common names are used without thought of their origin or cultural impacts upon the people encountering them. Jaime Morin Frye will dive into the ways we use language to describe plants and examine how the words we use influence inclusion in horticultural spaces.

Safeguarding the Southeast’s Rarest Plants: Perspectives from Conservation

Will Hembree

Conservation horticulture is an example of ex-situ plant conservation in the form of living collections used to maximize genetic diversity. The Southeastern Center for Conservation at the Atlanta Botanical Garden works with species of concern across the southeastern United States and the Caribbean, following best practices that include meticulous record keeping, running scientific experiments, administering novel protocols, and subscribing to shared adaptive management plan, all in the name of protecting earth’s natural resources for current and future generations.

Scanning the Horizon for the Future of Horticulture

David Bengston, PhD

Rapid social, technological, environmental, economic, and political change is the broad context for horticulture in the 21st century. The Forest Service’s “horizon scanning” project searches for emerging signals of change that could shape the future. This presentation will explore signals of change relevant for horticulture, to better anticipate and prepare for a turbulent future.
