The Barnes Arboretum, located at the Merion campus, contains more than 2,000 species/varieties of trees and woody plants, many of them rare. Founded in the 1880s by Joseph Lapsley Wilson and subsequently added to under the direction of Mrs. Laura L. Barnes, the collection includes a fern-leaf beech (Fagus sylvatica ‘Laciniata’), a dove tree (Davidia involucrata), a monkey-puzzle tree (Araucaria araucana), and a redwood (Sequoia sempervirens).

Other important plant collections include Lilacs, Peonies, Stewartias and Magnolias. The Horticulture school at the Barnes Foundation in Merion has offered a comprehensive, three year certificate course of study in the botanical sciences, horticultural practices, garden aesthetics, and design through a well-grounded, scientific learning experience since its inception in 1940 by Mrs. Barnes.
