Cliveden Grounds


Nestled in historic Philadelphia, the nearly 6 acres of beautiful lawn, garden, tree and brush at Cliveden often fascinate arborists, horticulturalists, and visitors alike. Our grounds are open every day, except for national holidays or special events. Please feel free to roam and picnic during your next visit!

Investigation by the Morris Arboretum of the University of Pennsylvania uncovered the Cliveden Tree chronology. This historic foliage can still be found today, contributing to the beautification and desirability of the Cliveden Grounds.
