The Barnes Arboretum at Saint Joseph's University offers a peaceful escape into a living botanical collection. This 12-acre arboretum, once part of the Barnes Foundation's original Merion campus, is a horticultural treasure showcasing thousands of rare and significant plant species amidst serene landscapes. It stands as a testament to Laura Barnes' passion for horticulture, complementing her husband Albert C. Barnes' renowned art collection and serving as a unique educational resource in the Delaware Valley.
Visitors can explore diverse collections, including the vibrant Magnolia Collection that bursts into bloom each spring, the fragrant Lilac Collection, and the extensive Laura L. Barnes Fern Dell, featuring nearly 100 varieties of hardy ornamental ferns. The arboretum is also home to a National Hosta Display Garden, recognized as the largest in the region, and boasts impressive rare trees such as the intriguing Monkey-puzzle tree, a towering Redwood, and the elegant Dove Tree. Pathways wind through formal gardens, woodlands, open lawns, and past a tranquil pond and stream, revealing a botanical diversity of over 2,500 woody and herbaceous plant taxa.

The history of the Barnes Arboretum began in the 1880s when Captain Joseph Lapsley Wilson, a horticulturist, started planting trees on the Merion property. In 1922, Dr. Albert C. Barnes purchased the land for his educational institution, the Barnes Foundation, with the agreement to preserve and expand Wilson's arboretum. While Dr. Barnes focused on his art collection, his wife, Laura Leggett Barnes, dedicated herself to the arboretum, becoming its director in 1928. Laura Barnes significantly expanded the plant collections, corresponding with notable institutions like Harvard University's Arnold Arboretum and the Brooklyn Botanic Garden. She also founded the horticulture school in 1940, establishing a legacy of botanical education that continues today. In 2018, the Barnes Foundation and Saint Joseph's University formed an educational partnership, with Saint Joseph's University now managing the arboretum and its educational programs, ensuring its preservation and continued growth.
Enjoy a leisurely walk, observe the unique plant specimens, photograph the seasonal blooms, and find a quiet spot for reflection by the pond or stream. Educational signage often provides insights into the collections.
Spring brings a riot of color and fragrance from flowering trees and shrubs like magnolias, lilacs, and peonies. Summers are lush and green, while fall showcases brilliant autumnal hues. Winters offer a serene, structural beauty, though specific activities might be limited.
