Jenkins Arboretum (48 acres) is a nonprofit botanical garden located at 631 Berwyn Baptist Road, Devon, Pennsylvania. The grounds are open to the public daily from 8:00 am to sunset with free admission. Early surveys of the property determined that the best plants to grow in the rocky, acidic soil would be those in the heath family (Ericaceae). Rhododendrons and azaleas were chosen as the primary collection. The Arboretum officially opened to the public in 1976 and today has one of the most significant collections of azaleas and rhododendrons in the country.
