It's finally time! 〰️
This Saturday!
The event all us dahlia people have been waiting for—the annual DSC Tuber and Plant sale is happening this weekend!
We will have a variety of show-quality tubers (including a special section of hard-to-acquire ones), plus well-established cuttings that are ready to go in the ground.
The event starts at 10am, and ends when we sell out (roughly around noon).
FREE, all ages, no pets please.
Support the Kickstarter for “DAHLIA” book, ends April 30!
DAHLIA is a hardcover photobook exploring the flowers of Golden Gate Park’s Dahlia Dell through color, form, and abstraction. Created over months of close observation, it reflects both the blooms and the community that cares for them.
