The Pennsylvania Horticultural Society believes horticulture can strengthen communities by increasing access to fresh food, creating healthy living environments, building deeper social connections, and growing economic opportunity.
"The Pennsylvania Horticultural Society connects people with horticulture, and together we create beautiful, healthy and sustainable communities."
The growth of PHS over these many years reflects the changes in horticulture itself, from an early focus on specimen plants and ornamental gardens viewed alone in their majestic beauty, to a more holistic understanding of plants as a tool for urban transformation. Since PHS began its highly effective greening programs in the mid-70’s, the impact on communities throughout the region has been dramatic. PHS understands that plants and gardens are linked to the health of people, the environment and the economic vitality of Philadelphia. Programs like Tree Tenders, Plant One Million, Philadelphia LandCare, Civic Landscapes and City Harvest are changing the conversation on urban decay to a story of hope and transformation, one of renewal and civic pride.
Each year, PHS produces the Philadelphia Flower Show, America’s largest and longest-running horticultural event, which features stunning displays by the world’s premier floral and landscape designers. Started in 1829 by the Pennsylvania Horticultural Society, the Show brings together diverse people and organizations to introduce the newest plant varieties, garden and design concepts, and organic and sustainable practices. Proceeds from the PHS Philadelphia Flower Show, including donations from foundations, corporations, government agencies, and individuals, support PHS programs and greening initiatives.
PHS invites people of all skill levels to participate year-round in educational workshops and events and, as members, volunteers and exhibitors. Together with our amazing partners, PHS is shaping the region through greening.
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.
