A group of public gardens, arboreta and historic houses with gardens in the Philadelphia region formed in 1989 to work together to promote the gardens and encourage visitors. Collectively the institutions attract more than two million visitors each year. The Collaborative has become a model for other public gardens, arboreta and historic houses all over the country.

In addition Greater Philadelphia Gardens has participated in 40 different special events including five exhibits at the Philadelphia Flower Show. In 1996, three of the gardens in Greater Philadelphia Gardens were featured in the award-winning main attraction exhibition.
