The Arboretum

at Historic Rittenhouse Town

Home to over 80 species of trees and shrubs, the Arboretum at Historic Rittenhouse Town is on our 20-acre historic site in the Wissahickon Valley Park in Philadelphia. It’s an inviting public garden dedicated to preserving and enhancing the beauty of the plant collection and engaging the community through horticultural educational programs, events, and volunteer projects. The arboretum features Magnolia Grove, dedicated to Dr. Jack Fogg who received his PhD in botany from Harvard University in 1929. His many accolades include cofounding the American Magnolia Society. The cherry collection runs along the north side of Monoshone Creek (also known as Paper Mill Run) that powered the early water wheels on site. As a Philadelphia Parks and Recreation site, the grounds are open from dawn to dusk, seven days a week.
