The RHS Award Of Garden Merit (AGM)


As part of our recent website makeover, we have indicated all of our hedging plants and lavenders that have been given the Royal Horticultural Society’s Award of Garden Merit (AGM). Since then, we have received a few enquiries about the Award…

The RHS introduced the AGM back in 1922 to help gardeners select plants “that best suit their individual growing conditions”. Today, the RHS’s criteria for The Award of Garden Merit require that a plant:
