Taught by Jenna O’Brien, this four-session course, held on Tuesdays, Oct. 1 to 22,  from 5:30 to 8:30 p.m., will focus on the bones of the garden with a survey of ornamental woody plants for residential landscape design. It will cover ornamental shrubs, small flowering trees, shade trees, and broadleaf and needle evergreens. Students will become familiar with the many garden-worthy woody plants that thrive in Zone 5. The course covers plant identification, selection, siting, cultivation, and possible design uses. Students should dress for outdoor field study. All students participating in this class as part of the Horticulture Certificate Program are required to complete a final project.
