The Cornish Dahlia Society was formed in 1982 and aims to promote Dahlia growing throughout Cornwall and the South West and to hold two quality Dahlia Shows each year.  We also hold events during the year which are open to both members and non-members.

Our three day Main Show held at the Lost Gardens of Heligan is one of the largest in the South-West and is complemented by a Dahlia Display at the Lost Gardens of Heligan which features over 1600 dahlias all grown and provided by the society.
