Syn. Azalea.

Genus of more than 1000 species of evergreen and deciduous trees and shrubs from Europe, Asia, Australasia and North America, particularly southwestern China, Tibet, Burma, northern India and New Guinea.

Evergreen rhododendrons vary greatly in size and usually have bell-shaped flowers with 10 stamens.

Azaleas have smaller, thinner leaves and are generally medium-sized shrubs with smaller, funnel-shaped flowers with, usually, 5 stamens.
