Description

A woody evergreen or deciduous shrub in the Ericaceae family.  It takes on an upright, rounded, dense, spreading shape, growing irregular with age.  The elliptical foliage is dark green and leathery, and the crushed leaves have an aromatic fragrance.  Good for mass planting.

Grows best in partial shade and cool, moist, well-drained, acidic, rich soil.  It can tolerate full sun in certain areas, although windy sites should be avoided.

Wildlife Value:  Flowers attract hummingbirds. Members of the genus Rhododendron support the following specialized bee: Andrena (Andrena) cornelli.

Insects, Diseases, and Other Plant Problems:  Rhododendrons are susceptible to insect and disease problems.  Insect problems include aphids, borers, lacebugs, leafhoppers, mealybugs, mites, nematodes, scale, thrips and whitefly.  Leaf spot disease can develop if grown in deep shade or suffers drought stress. Other diseases include canker, crown rot, root rot, rust, and powdery mildew.  Full sun can scortch the leaves and the roots rot if soil does not drain well.   A healthy plant in the right place with proper maintenance should have few problems.
