The Barnes Arboretum
 
The Barnes Foundation's Arboretum School has been educating students in the field of horticulture since its creation under Laura Leggett Barnes in 1940. Experienced instructors integrate a combination of classroom lectures, field study, hands-on practice, and visits to other gardens in this comprehensive program incorporating science, design, and plant knowledge. Upon successful completion of the three-year program that meets one day per week, students receive a certificate of merit in horticulture.

Workshops and Lectures:
Workshop and lectures include:
Horticulture certificate program, Make More Plants: propagation workshop , Floral Design & Contemporary Botanical Illustration.Learn more

Certificate program
Our three-year certificate program takes a comprehensive approach to horticultural science, methods, and design. Learn more

Our campus in Merion, originally purchased by Dr. Barnes and his wife Laura in 1922, features a Paul Philippe Cret designed home and gallery surrounded by a 12-acre Arboretum.

The entire arboretum can be easily walked in a visit, its magnificent collection, astonishingly large and diverse for the size of the property, is worth lingering over: 2,000 species of woody plants, including collections of Stewartia, Aesculus, Phellodendron, Clethra, Magnolia, Viburnum, and Lilac, as well as 38 PA champion trees. Other collections include roses, peonies, hostas, medicinal plants, and over 200 hardy ferns. Made up of her favorite types of plants, the collection was assembled by Mrs. Barnes specifically for teaching purposes. A herbarium of more than 10,000 specimens complements the living collection and is available to the Foundation's horticulture students and other scholars by appointment.
