Free Calhoun Lecture

Every other year, the Garden offers a special opportunity for teachers to supplement their life science curriculum with presentations by leading horticulturists, explorers, and researchers.

The lectures are free and open to students in grades 6 - 12. After the lecture, participating classes are invited to take a self-guided tour of the Garden.

The Calhoun Lecture series is made possible through the generous support of the family of Marion Peel Calhoun.

2017 Lecture

Saving Georgia's Wild Orchids

Wednesday, March 22, 10:30 - 11:30 a.m.
Presented by Matt Richards, Conservation Horticulture Manager

The southeastern United States is home to more than 100 orchid species. These fascinating plants are vital to healthy ecosystems, not just in rural and wild regions, but even in urban areas. Many native orchid species are on the decline due to habitat loss and illegal poaching, and so the Atlanta Botanical Garden has led a robust orchid conservation movement across the Southeast for more than a decade. Join Conservation Horticulture Manager Matt Richards as he takes an in-depth look at Georgia’s native orchids, their relationship with pollinators, and the conservation efforts to protect orchids throughout the entire Southeast.
