Annual Dahlia Show:
Saturday and Sunday, August 17-18, 2024

County Fair Building, Golden Gate Park

Each summer, on the third weekend in August, the Dahlia Society of California draws thousands of visitors to its annual show in the enormous Hall of Flowers. Growers from all over the state bring their best blooms. Blooms in all categories are judged and awarded ribbons, including the elusive “Best in Show.” Other categories: Best Photo; People’s Choice Award; Best Arrangement; Best Junior Bloom; and “Nature’s Oddities.” You must be a member to compete, but the public is welcome to see this eye-popping event.



We are always looking for volunteers to help us maintain the Dahlias located at the Dell in Golden Gate Park. You must be a member to volunteer.
