The Pennsylvania Horticultural Society (PHS) is a not-for-profit membership organization founded in 1827. PHS produces the Philadelphia Flower Show and sponsors events, activities, and publications for novice gardeners, experienced horticulturists, and flower lovers of all ages.
PHS's urban greening program, Philadephia Green, works with community groups and residents in neighborhoods throughout the city to plan and implement greening projects. Philadelphia Green also partners with private and public organizations to landscape and maintain public spaces in the city's downtown. Proceeds from the Flower Show, along with funding from individuals, foundations, corporations, and government agencies, help to support its projects.
