The horticultural cultivation of the dahlia plant has resulted in over 57,000 registered cultivars of dahlia.[1] Several of them are listed below.
In North America the American Dahlia Society[2] is responsible for the process of accepting a named variety as a cultivar. They also publish the list of currently found Dahlia Cultivars in North America.
The list of Cultivars then might be divided into at least three lists: (1) Named Cultivars from North America (2) Named Cultivars from the International Dahlia Society, (3) Named Cultivars from the Netherlands
Should this list include historic Cultivars that now can no longer be found? Should this list include photos of the Cultivars?In Europe, and the UK, The International Dahlia Society attempts to be responsible for cultivar names,[3] [4] but there also is a Dahlia Registrar in the Netherlands.[5]
