The Barn at the Lost Gardens of Heligan is the ideal venue to view hundreds of top exhibition dahlias in our Three Day Main Show. Our show is known as the Premier South West Dahlia Show and features classes for beginners, novices, intermediate and top growers.
If love dahlias then it is a worthwhile visit and to chat to the expert growers for the questions to all your questions.
You can also visit the dahlia display garden where the Cornish Dahlia Society have propagated, grown, planted and cultivated over 1400 dahlias to create an incredible display.
