Join Michael Dirr, professor of horticulture at the University of Georgia, and a UMass Amherst alumnus, for a guided walk around the UMass Amherst campus, followed by a book signing.

There will be two walkabouts. Choose either the morning walk from 9 to 11:30 a.m. or the afternoon walk from 1:30 to 4 p.m.

For most people who work with trees, Michael Dirr needs no introduction. He is the author of numerous books on woody plants that have become staples on our desks. He also has some New England roots, as he earned his Ph.D. from UMass Amherst.

His fingers are always on the pulse of the nursery industry, scouting for new introductions, and having himself introduced 15 trees into commerce. He has established several arboreta, consults on tree selection, and has penned tree guides for many campuses. The green industry has tremendously benefited from his keen interest in evaluating trees and his enthusiasm to share it with us.

His new The Tree Book, co-authored with Keith S. Warren, is the go-to reference to more than 2,400 species and cultivars. The featured trees include those widely available in the nursery trade, some new and promising choices, and a selection of overlooked options that deserve renewed interest. Each tree profile includes the common and botanical names along with details on foliage; flowers, seeds, fruits, and cones; native range; adaptability; and popular uses in landscapes. The Tree Bookis a must-have resource for landscapes architects, city foresters, horticulturists, and enthusiastic home gardeners.

We will be offering copies of The Tree Book for sale on the registration form. Note: Ptogrddot Dirr will only be able to sign books purchased as part of your registration or at the door (no personal copies, please!).
