Testing the best plants
Plant trials provide the opportunity for multiple varieties of the same plant to be grown together, side-by-side, for comparison. They offer an excellent method to judge plant performance, and trials may run for one, three or five years depending on the nature of the plant. A panel of industry experts regularly assesses the growing habits of each plant during the trial.
Current plants being grown in the Trials Garden for assessment include dahlias, hellebores, sweet peas, red-flowered roses and hebes.
