Description

Rhododendron periclymenoides, commonly called pinxterbloom azalea, is a deciduous shrub that is native to moist woods, swamp margins and open areas from Massachusetts to South Carolina and Tennessee. It is a dense, bushy, suckering shrub that typically grows 2-6’ (less frequently to 10’) tall.  Its bark is gray to reddish-brown and finely shredded.

It does best with a half day of sun.  It has a slow growth rate.

Regions:  Mountain, Piedmont, Coastal Plains

Seasons of Interest:

   Bloom:   Early spring/spring           Nut/Fruit/Seed:  Fall

Wildlife Value: This plant has a low resistance to damage from deer.  Hummingbirds and swallowtail butterflies are attracted to the blooms.  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 scorch the leaves and the roots rot if the 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.

Formerly known as Rhododendron nudiflorum.
