Award of Garden Merit
Award of Garden Merit (AGM)
The RHS Award of Garden Merit (AGM) helps gardeners choose the best plants for their garden
Plants that perform
You may well have seen the AGM logo (right). A cup symbol on a plant’s label shows that it has earned the AGM – it's our seal of approval that the plant performs reliably in the garden.
Awards are usually given after a trial period, often at Wisley, and are judged by our expert forums. RHS awards can also be given by 'roundtable assessment'. This is given when a forum of horticultural experts meet to debate the characteristics and garden performance of plants that the Society is unable to trial.
Roundtable discussions are used when the plant group in question is impractical or impossible to trial or isn't in the trials plan for the next five years, and has the following attributes: current lack of AGMs, relevant to today’s gardener and outside expertise has been identified.
What is the AGM?
With more than 75,000 plants available in RHS Plant Finder alone, how can you tell which plants are best for all-round garden value? The AGM is intended to help gardeners make that choice, and is only awarded to plants that are:
- excellent for ordinary use in appropriate conditions*
- of good constitution
- essentially stable in form and colour
- reasonably resistant to pests and diseases
