Description

Loose multi-stemmed woody shrub; easy to grow; fragrant flowers; native to lower southeastern US, but not native to North Carolina; drought tolerant.

Wildlife Value: Flowers attract humingbirds. 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.

HIGHLY TOXIC, MAY BE FATAL IF EATEN!
