The free dahlia reference

Every dahlia variety, from blush to fireball.

Honest growing notes, real ADS classification, and a lookalike for the ones you can never get a tuber of. We sell nothing, so the tradeoffs are in here too: the colors that never come twice, the viruses nobody advertises, the stems too short to cut.

Informal Decorative

Fully double blooms with twisted, curled, or wavy ray florets arranged irregularly. Most of the famous dinnerplates, including Cafe au Lait, live here.

Forms and sizes follow the American Dahlia Society Classification and Handbook of Dahlias. By the way: "dinnerplate" is catalog language for the biggest blooms, not an official class. We explain on every profile.
