RHS Award of Garden Merit Clematis
Here are all the clematis we stock which have achieved the
Royal Horticultural Societies Award of Garden Merit.
This award is given to plants that have been submitted to the RHS for trial and proven to be particularly good garden worthy plants under a number of factors, including flowering ability, strength, disease & pest resistance. At Thorncroft we would only select and indeed sell clematis that we believe have these qualities but the AGM is a helpful guide to selecting excellent plants.
