RHS Award of Garden Merit® Plants

The Royal Horticulture Society's Award of Garden Merit goes only to plants that meet a minimum of the following requirements: "excellent for ordinary use in appropriate conditions, available( at nurseries and garden centers ), of good constitution, essentially stable in form and colour, and reasonably resistant to pests and diseases". The AGM list is updated periodically to ensure that these are still the best of the best. "Awards are only made after assessment by an RHS forum of experts appointed by the Society to assess that particular trial. Each forum has its own area of expertise, and draws upon the experience of a wide range of experts, including nurserymen, specialist growers and well-known horticulturists. This assessment must then be ratified by the relevant Plant Committee. The trial and assessments usually take place at one of the four RHS Gardens but can also take place at one of our partner gardens, National Trust gardens or commercial nurseries."
