Delphinium shows

The Society holds several shows through the year in various parts of the country (see our events for details). Members are invited to enter their prize blooms and florets for judging and display and the society has some lovely cups and trophies to award to the lucky prize winners.

Why not join in the fun and see how your plants compare?

Members are often needed to help out at our shows too so please contact us if you are available to help.
