Located inside a historic former carriage house in Mellon Park, the Garden Center was established in 1948 as a site for groups to meet and to cultivate botanical knowledge, inspire creative minds and spread the joy of gardening.

In this image, from the May 1954 issue of Carnegie Magazine, the original carriage house of the Mellon Estate is seen. The carriage house is one of two historic facilities constructed in the 1910s on this site which will be preserved and renovated as part of the Garden Center project. 

Phipps Garden Center actively supports numerous organizations and nonprofits by providing facilities for regular meetings, conferences, and exhibitions, including:

  • Pittsburgh Bonsai Society meetings and exhibitions
  • Orchid Society of Western PA meetings and exhibitions
  • Three Rivers Birding Society
  • Western PA Herb Society
  • Greater Pittsburgh Aquarium Society
  • Hosta and Daylily Society
  • Executive Committee of the Garden Club of Allegheny County
  • Native Plant and Sustainability Conference
  • Summer Short Course
  • Three Rivers Urban Soils Symposium
  • Sustainable Landcare Accreditation Training
