Rhododendron genus. There are around 800 evergreen, semi-deciduous and deciduous shrubs and trees in this genus. They are grown mainly for their mass display of flowers, which will vary greatly in size from tiny blooms to large trumpets. They usually have clusters of blooms from the branch tips, and appear in every colour except bright blue. They are mainly broad leaved with roughly elliptical, usually deep green leaves.

Grown mainly for the beauty of the flowers. Ground cover & interesting leaves. Suitable for northern and eastern aspects.
There are many species but they all share the same general cultivation needs. They are fully hardy to frost tender, min 4-7C and will prefer dappled shade, but a considerable number will tolerate full sun, especially in cool climates. They will need loose open, well-aerated, acidic soil with plenty of humus to retain moisture. In wet areas or gardens with alkaline soil you should plant them in raised beds. Shallow planting is essential, as plants are surface-rooting. Dead-head spent flowers, wherever practical, to encourage energy into growth rather than seed production.
Propagate by simple layering, dropping or semi-ripe cuttings in late summer.
Yellowing leaves are usually caused by poor drainage, excessively deep planting or lime in soil. Weevils and powdery mildew may also cause problems.
