Members can attend in person or on Zoom. If coming in person, we meet in the County Fair Building classroom located off the parking lot at 10th Ave. and Lincoln.

FREE ADMISSION
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.
