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. If you grow dahlias why not have a go at our beginners classes – check the 2026 Show Information page (link below).
If you have some dahlias flowering in your garden then bring some blooms along and enter the Peoples Dahlia Competition, its free to enter (like all our classes) and you could walk away with some prize cards. You can bring the blooms along between 11am and 1pm and we even provide the vase and will help you enter.
You can also visit the dahlia display garden where the Cornish Dahlia Society have propagated, grown, planted and cultivated over 1600 dahlias to create an incredible display.
