North American Dahlia Society

We Love Dahlias!

Welcome Message

The American Dahlia Society (ADS) was founded in 1915 and is composed of over 70 independent local societies in the US and Canada.

We are a non-profit organization founded for the purpose of stimulating interest in, disseminating information about, and promoting the culture and development of, the dahlia.

If you also love dahlias, please consider joining the ADS. You may join "at large" from this site, but for a more exciting experience, join ADS (and receive a discount) via a local society. Find a society in your area by using the ADS Societies button above or to the right. In a local society you will meet dahlia enthusiasts, learn first-hand from local growers, and have a lot of fun!
