Crozer Arboretum, now called the Crozer Garden, is a 12-acre garden park in Upland, Pennsylvania, on the grounds of the Crozer-Chester Medical Center. Once part of the Crozer Theological Seminary campus, it preserves large specimen trees from the mid-19th century that give the landscape an older estate character. The grounds are known for more than 1,400 rhododendrons, along with native herbaceous plants and shrubs, lawns, two ponds, natural springs, and walkways. Together with the nearby Leona Gold Garden and the Crozer Greenhouse, it remains an important green space and a surviving part of the former seminary grounds.
