View source for List of Award of Garden Merit rhododendrons

{{Short description|none}}
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 [[Hardiness (plants)|hardy]] evergreen [[shrubs]] with abundant, brilliantly-coloured, trumpet-shaped flowers, often in large spherical trusses. The group known as [[azalea]]s are often (but not always) more compact with smaller flowers and leaves, and may be [[evergreen]] ([[subgenus]] ''[[Rhododendron subg. Tsutsuji|Tsutsuji]]'') or [[deciduous]] (subgenus ''[[Rhododendron subg. Pentanthera|Pentanthera]]''). Most rhododendrons bloom for a short period in late spring (April to May in the [[temperateness|temperate]] Northern Hemisphere). They are seen at their best in a woodland setting with light dappled shade, in [[humus]]-rich [[soil pH|acid soil]].<ref name=RHSAZ>{{cite book|title=RHS A-Z encyclopedia of garden plants|year=2008|publisher=Dorling Kindersley|location=United Kingdom|isbn=978-1405332965|pages=1136}}</ref>
