Like trees and plants? Better yet, like talking about them? The Morris Arboretum wants you.

The Arboretum is looking for volunteer tour guides and is willing to train. The guides are integral to the Arboretum’s operations, explaining its history and collections to visitors. The four-session training course, held on successive Thursday evenings beginning Sept. 7 or successive Saturday mornings beginning Sept. 9, introduces guides to all they need to know about the Arboretum and its history.

The course is free to Arboretum members; the $50 non-member fee includes a one-year household membership. Participants should bring bag lunches and dress appropriately for the weather. The Arboretum is at 100 Northwestern Ave., Chestnut Hill. To register or for more information, call 215-247-5777, ext. 128.
