RHS Award of Garden Merit
The Royal Horticultural Society's Award of Garden Merit (AGM) helps gardeners make informed choices about plants. This award indicates that the plant is recommended by the RHS. Awards are usually given after a period of trial at an RHS garden. Plants are judged by one of the RHS plant committees.

Award plants in focus
RHS Plant Trials Bulletins are produced to focus on popular and interesting AGM trials. This set of full colour bulletins provides detailed information about all AGM winners announced following a trial. The bulletins also offer comments from committee members about reasons for holding trials of plants, explanations of any nomenclature problems resolved by RHS botanists and easy-to-use 'planting guides' to help you chose a cultivar for your own garden.
