NDS Dahlia

Welcome to the National Dahlia Society

Welcome To The National Dahlia Society.

The National Dahlia Society was formed in 1881 and for over a century has given unbroken service to gardeners interested in this wonderful flower. We are now a registered charity, which seeks to promote the dahlia by means of exhibitions (shows), trials and conferences. We are the world’s largest all-dahlia society and annually hold our main exhibitions at RHS Wisley and Newby Hall, Ripon,Yorkshire, with reduced admission for members of course!

NDS Societies

A number of dahlia and other societies are Affiliated Societies of the National Dahlia Society. This gives them the right to enter inter – society classes at National Shows and to award National Dahlia Society medals at their own shows, as well as advertising their presence in NDS publications. In addition they receive the literature that individual members receive on joining. If your society is not affiliated but wishes to become so, then  please click the link below to see how to become affiliated.
