SF’s 2025 Dahlia Competition in Golden Gate Park (Aug 16-17)

EVENT UPDATE: There are no upcoming events known for this event series - please check the organizer website for any updates.

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.

The Dahlia Society of California Flower Show in 2025 will be held at the Hall of Flowers (San Francisco County Fair Building) at 9th Avenue and Lincoln Way in San Francisco.

In 2024, the event hours were: Saturday from 10am – 5pm and Sunday from 10am to 4pm. We don’t know the hours for 2025 yet, but we expect it to be similar to past years.
