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. The Arboretum was established by H. Lawrence in 1968 as a living memorial to his wife Elisabeth Phillippe Jenkins. In his will, Mr. Jenkins designated that the 20-acre property become a “public park, arboretum, and wildlife sanctuary for use by the public and responsible organizations engaged in the study of arboriculture, horticulture, and wildlife for educational and scientific purposes…”
In addition to the Rhododendron collection, the Arboretum features numerous native trees, shrubs, ferns, and wildflowers that can be found in several different garden areas. The botanical diversity of the site also supports many varieties of wildlife. Foxes, turtles, hawks, small mammals, and nearly 100 species of songbirds frequent the Arboretum.
