Azalea—Rhododendron spp.
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.
