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!
