The Award of Garden Merit (AGM) issued by the Royal Hoticultural Society (RHS) helps gardeners find reliable, consistent plants that will provide particularly good value in the garden.The award is granted after trials at the RHS’ garden at Wisley in Surrey and/or assessment at specialist collections or discussion at meetings. There is a set list of criteria that plants have to meet to be deemed worthy of the AGM. For more information on the AGM please visit the RHS Website.
Nursery owner, Tim Fuller, has been involved with judging the trials at RHS Wisley since 2008.
