Upcoming Events
Tuber & Plant Sale
Saturday, April 25, 2026
10AM–12PM *(ends earlier if we sell out)
County Fair Building, Golden Gate Park
Public Event: FREE Admission, All Ages
Each spring, the Dahlia Society of California holds its annual Tuber and Plant Sale. Here you’ll find a variety of dahlia tubers and young plants for sale at low prices. Pictures are displayed, so you can see what your bloom will look like. These tubers and plants are donated by members of the society. Proceeds support the Dahlia Society of California. Jumpstart your garden with young plants ready to “plug and play.”
Come early for best selection! We often sell out quickly at this popular event.
