Rhododendron atlanticum (Coastal Azalea)

Coastal Azalea, Dwarf Azalea, Azalea atlantica, Midseason Azalea


Native to the south eastern coastal plains of the United States, Rhododendron atlanticum, commonly known as Coastal Azalea or Dwarf Azalea, is a delightfully fragrant, semi-dwarf, deciduous Azalea. Blooming before the leaves emerge in mid to late spring, its funnel-shaped, white flowers, up to 1.5 in. wide (3-4 cm), with elegantly protruding stamens, are often softly blushed with pink on the outside. They bloom in clusters of 3 to 13 and contrast beautifully with the deciduous foliage of elliptic, blue-green leaves. Attractive and tough, this low, spreading shrub has been used in Azalea breeding programs to obtain sweet-smelling deciduous Azaleas. The powerful musky fragrance of this Azalea makes it a valuable addition alongside walking paths.

  • Grows vigorously up to 2-3 ft. tall (60-90 cm) and 4-5 ft. wide (120-150 cm). Spreading by underground stems, this Azalea may develop into large colonies in sandy soils. Its spreading habit may be more limited in heavier soils
  • Winner of the Rhododendron of the Year Award of the American Rhododendron Society for the North East, South East and South West regions.
  • A sun to part shade lover, this plant is easily grown in moist, acidic, humusywell-drained soils. Tolerates full sun in cool moist sites. Plant shallowly in a location protected from strong winter winds. Protect from frost to prevent damage to flowers. Mulch annually with leaf mould to retain moisture, control weeds, and cool the soil.
  • Perfect for shrub borders or mixed borders and shade gardens.
  • Attracts butterflies, hummingbirds and birds
  • Removing spent flowers promotes new growth.
  • All parts of plant are poisonous if ingested
