World's Largest Garden Party

Each Spring, Greater Philadelphia Gardens join forces to present the “World’s Largest Garden Party,” a cornucopia of gardening happenings throughout the region that includes plant sales, wildflower walks, garden tours, hands-on workshops, lectures, and evening galas. This garden celebration takes place throughout the month of June.

Greater Philadelphia Gardens is the voice of many gardens and offers a central site that makes it easier for visitors to discover what each garden, arboretum or historic house has to offer.
