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, often Wisley. Plants are judged by one of the RHS plant committees.
