An Annual Tradition

Each summer, on the third weekend in August, the Dahlia Society of California, San Francisco draws thousands of visitors to its annual show in the enormous Hall of Flowers. Growers from all over the state (and sometimes country!) bring their best blooms to be judged and awarded ribbons. 

You must be a member to compete, but the public is welcome to see this eye-popping event.

    If you’re interested in becoming a judge or clerk, or are an exhibitor who wants to learn the details of how your dahlias will be evaluated, we encourage you to take the Judging Seminar on Saturday, July 25, 2026.
