Morris Arboretum of the University of Pennsylvania

Established in 1887 as a private estate and later developed as a public arboretum, Morris Arboretum preserves historic landscape infrastructure, specimen trees planted in the late 19th and early 20th centuries, and original estate roads and horticultural buildings. The site documents the evolution of horticultural practice and public garden infrastructure in Philadelphia and remains an active center for plant collections and landscape preservation. Its historic features include carriageways, nursery beds, and preserved estate architecture integrated into the living collection.
