Description

Dwarf azalea, is a compact, loosely-branched, stoloniferous, suckering, deciduous shrub in the Ericaceae (blueberry family).. Typically it matures to 2 to 3 feet tall and as wide, but infrequently rises to as much as 6 feet tall. Plants which mature to 1 to 2 feet tall are often commonly called dwarf azalea in recognition of their small size. It is a woody, evergreen or deciduous shrub that spreads by underground stolons.

This azalea is native to coastal plain areas from New Jersey and Pennsylvania south to Georgia.

They prefer full sun to partial shade, consistent moisture, and well-drained soil, they don’t like “wet feet” which leads to root rot. Mulching the soil with needles, bark, or compost will help it stay moist and manage a consistant soil temperature. Place plants where they can be protected from strong winter winds and frosts as leaves can burn and flowers can be damaged.

This species is often used in azalea breeding programs because of its potent flower fragrance.

Fire Risk: This plant has a medium flammability rating.

Full sun can scorch the leaves and the roots rot if the soil does not drain well. This plant is frequently damaged by deer.
