35 Types of Azalea Flowers (Old, Large & Evergreen Varieties)

Azalea shrubs belong to the Rhododendron genus. Rhododendron is a genus of 400 to 1000 species and includes both of what we commonly call rhododendrons and azaleas. There are basically two categories of azaleas available, evergreen and deciduous. The variety within the two categories differ in size, shape, flower color and light preference.

Azaleas are grown for their showy spring flowers and in the case of evergreen types for their attractive winter foliage. True rhododendrons have 10 stamens in a flower and azaleas have only 5. Much hybridization has resulted in a great number of hybrid cultivars. Of note to gardeners in cool temperate areas are the large and small leaved evergreen rhododendrons and the evergreen and deciduous azaleas.

Deciduous azaleas are deciduous shrubs that grow as multi-stemmed plants from the ground. They have thinner leaves than the evergreen azaleas and rhododendrons and drop their leaves in fall. Flowering occurs early in spring before or just as the new foliage emerges. They have been widely hybridized and many cultivars procduce a lavish display of flowers. Colors run from white to yellow, pink, orange, red and lavender.
