Join us in exploring the wide range of conifers, from shrubby dwarfs to towering trees.
In this course, grow your knowledge on specific identification characteristics of conifer trees as we focus on plants arranged by family including Pinaceae (Pines, Spruce, and Firs), Cupressaceae (Arborvitae, Cypress, and Juniper), Taxaceae (Yews), and others. Once comfortable with your identification skills, deepen your knowledge by learning the growth patterns of different conifer trees and their uses in the landscape. The class includes two walks through Longwood to practice your identification skill.
