About The Greater Philadelphia Dahlia Society

The Greater Philadelphia Dahlia Society was formed in 1948 and continues promoting its members’ favorite flower. Throughout its history, the GPDS has been the “home” of dedicated and knowledgeable dahlia growers.

A historical highlight was the hosting of the national show during the nation's bicentennial celebration in 1976.

Our society’s annual show is held each September at what we believe is the most spectacular of show venues - Longwood Gardens in Kennett Square, PA.
