Rhododendron atlanticum, the Coastal Azalea, is a common understory plant along the south eastern coastal plains of the United States. The white flowers are 1 to 1.5 inches across, but are often blushed with pink on the outside and some have a yellow blotch.

Collected by John Clayton in 1743, this plant was appreciated more in England than in its native land. The plant habit is relatively low but stoloniferous. Spreading by underground stems, R. atlanticum can develop into very large colonies of an acre or more in sandy soils.

R. atlanticum is easy to propagate, and makes a nice landscape plant in heavier soils which will restrict the spreading habit.
