Native to the southeastern 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 mold 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 the plant are poisonous if ingested.
  • Toxic to dogs, toxic to cats, toxic to horses.
