Select from our RHS AGM Seed range

The RHS Award of Garden Merit (AGM) helps gardeners choose the best plants for their garden. You may well have seen the AGM logo. A cup symbol on a plant’s label shows that it has earned the AGM – it's the RHS seal of approval that the plant performs reliably in the garden. Awards are usually given after a trial period at an RHS Garden, often Wisley, and are judged by RHS expert forums.

RHS awards can also be given by 'round table 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 in one of the RHS gardens.
