Just how dumb do you feel when someone says “You’re in the Garden Club.  What’s this tree called?” Perhaps you smile and say it’s a native Eastern whortleberry.  Lie no more. In just a few hours on Sunday, October 25,  you can learn to identify 90 percent of the trees growing in Boston, both native and nonnative (like the ailanthus, below). Beginning in the classroom in the Hunnewell Building at the Arnold Arboretum, you will briefly review the characteristics of the 25 most common trees and learn the botanical terminology necessary to describe them. You will then walk the grounds of the Arboretum to look at mature specimens of these trees. Your instructor is Kyle Port, Manager of Plant Records at the Arboretum.
