List of Award of Garden Merit rhododendrons

Last updated

The following is a list of rhododendron cultivars and species which have gained the Royal Horticultural Society's Award of Garden Merit. They are mostly hardy evergreen shrubs with abundant, brilliantly-coloured, trumpet-shaped flowers, often in large spherical trusses. The group known as azaleas are often (but not always) more compact with smaller flowers and leaves, and may be evergreen (subgenus Tsutsuji ) or deciduous (subgenus Pentanthera ). Most rhododendrons bloom for a short period in late spring (April to May in the temperate Northern Hemisphere). They are seen at their best in a woodland setting with light dappled shade, in humus-rich acid soil. [1]

Maximum dimensions are shown in metres.
