The Dahlia Society of Ohio (DSO) was founded in 1930.  We are one of over 70 societies that comprise the American Dahlia Society (ADS),

We are a  501(c)(3) non-profit organization whose primary objectives are to encourage the cultivation of dahlias, exchange information about dahlias, and increase public awareness of dahlias.
