Description

Crushed leaves have an aromatic fragrance; dark green leathery foliage; good for mass planting.

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.  Diseases include canker, crown rot, root rot, leaf spot, 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. This plant is frequently damaged by deer.
