The Pennsylvania Horticultural Society connects people with horticulture and together we create beautiful, healthy and sustainable communities.
The Pennsylvania Horticultural Society, an internationally recognized nonprofit organization founded in 1827, advances the well-being of the Philadelphia region by creating healthier living environments, building deeper connections between people, and increasing access to fresh food and economic opportunity. Fueled by a diverse community of supporters, PHS delivers impact through initiatives in more than 250 neighborhoods, an expansive network of public gardens and landscapes, and the nation’s signature gardening event, the Philadelphia Flower Show. PHS invites everyone to garden for the greater good as a participant, member, donor, or volunteer.
PHS headquarters is located at 100 North 20th Street (20th and Arch Streets) in Philadelphia, Pennsylvania. In addition to administrative offices, the building houses the PHS McLean Library, which contains the most extensive collection of horticultural books in the Greater Philadelphia region.
