The Scott Arboretum of Swarthmore College offers the region’s most intimate, authentic, accessible, and replicable horticultural experience. We offer over 4,000 different taxa planted in a variety of small, intimate gardens replicating the experience of home gardens. Most plants are labeled to allow home gardeners to find these plants in the trade and add them to their own gardens. The Scott Arboretum is also free and open to public 365 days a year dawn to dusk. In addition to these accessible hours, the Arboretum can be reached via bus and train from Philadelphia and surrounding areas. Our free admission, free parking, and public transportation access allow us to be the most accessible institute of public horticulture in the region. We also offer over 60 educational programs to help the gardeners who visit us each year.

We identify 19 plant collections and 23 gardens in our visitor brochure.  The Arboretum's collections of hollies, magnolias, and oaks have gained recognition as registered collections in the Plant Collections Network.  We annually participate in the National Boxwood Trials as well as an evaluation program with the International Clematis Society.
