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."

Huge 4-5" double blooms are intensely fragrant! Aimee Yoshioka is the largest flowered of all Gardenias with large, glossy, dark green foliage on a vigorous and moderately fast growing evergreen shrub. The large dark foliage provides a wonderful foil for the large white flowers. Easily trained into a tree standard. Aimee is also considered to be one of the largest growing Gardenias, particularly in mild winter climates where it is known to reach 10-12' high but 5-6' may be more typical. Item# 1154.
