Tree ID 101
Single session on Saturday, August 22 or August 29, 2026 | 11 a.m.–3:30 p.m.
Preregistration Required
If you’re new to tree identification or need a refresher, this class is for you. You’ll learn the fundamental concepts used in dendrology while being introduced to the Garden’s most common trees. The instructor will share some relevant botanical terminology, but will largely apply a jargon-free approach. Participants will leave class feeling more confident in their ability to identify regional trees, and with recommendations for resources and strategies to improve their own independent self-study. Awareness of trees is one of the best portals into creating a closer relationship with land and nature! Class will break for 30-minute lunch.
