Description

Piedmont Azalea is a woody, evergreen or deciduous shrub in the Ericaceae family. It is native to the mountains of SC and GA. The flowers appear in large clusters in April in a variety of colors from yellow to pink to red. For an azalea, It is tolerant of heat and humidity.

Plant in humus-rich acidic moist but well-drained soils in partial shade to dappled shade. Poorly drained soils will lead to root rot. Use in a woodland garden, for naturalizing, foundation plantings, or as a specimen, hedge, or shady shrub border.

VIDEO Created by Elizabeth Meyer for "Trees, Shrubs and Conifers" a plant identification course offered in partnership with Longwood Gardens.
