The RHS Delphinium Committee
The Committee is a source of expertise for the Society for advice on all matters regarding delphiniums. The Committee is responsible for judging all individual exhibits of delphiniums at the London Flower Shows. It is also responsible directly or through a subcommittee, for selecting cultivars for Award of Garden Merit assessment and for judging the relevant trials at Wisley.
RHS trials
The regular trials of delphiniums have long been a great attraction to visitors to Wisley, to whom they demonstrate exemplary cultivation, as well as the means to identify the most outstanding cultivars.
