Taught by Jenna O’Brien, this four-session course 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 ID, selection, siting, cultivation and possible design uses.
