Azalea—Rhododendron spp.
Family Ericaceae (Heath family)

Plant identification

Azaleas can be evergreen or deciduous flowering shrubs with a wide range of colors. Their size varies by species; both large and small shrubs are found.

Optimum conditions for growth

Azaleas generally grow best in filtered shade and consistently moist soils; some plants can tolerate Southern California conditions. They prefer to grow in acid soils with high organic content and excellent drainage. Mulches around plants help to conserve moisture and keep roots cool.
