Physical Description
These perennial shrubs have tough, glossy, smooth-margined evergreen leaves. The large, showy flowers are in terminal clusters and have five white, pink, or red petals. Some horticultural varieties have yellow or orange petals.

One major difference between azaleas and the rest of the rhododendron genus is their size. Another is their flower growth; rhododendrons grow their flowers in stripers, while most azaleas have terminal blooms (one flower per flower stem). However, they have so many stems that during the flowering season they are a solid mass of color. Azaleas are recognized by these flowers blooming all at once, in a showy display for a month or two in spring. The exception to this rule is a small group of azaleas which grow their flowers in tight terminal clusters.

So how would you be able to identify an azalea, as distinct from a rhododendron? In general, rhododendrons are larger shrubs than are azalea plants, and, as just said, they have larger leaves. Also, in general, azalea flowers have five stamens, while the rhododendron flowers have ten stamens. Finally, unlike rhododendrons, many azalea plants are deciduous.
