Roseshell Azalea, Early Azalea, Woolly Azalea, Rhododendron roseum, Azalea prinophylla, Rhododendron nudiflorum var. roseum, Midseason Azalea, Deciduous Azalea
Prized for its delightful fragrance and stunning floral display, Rhododendron prinophyllum (Roseshell Azalea) is a vigorous and showy deciduous Azalea. In mid to late spring, abundant funnel-shaped, rose pink flowers, 1-2 in. wide (2-5 cm), with elegantly protruding stamens, appear in large clusters of 4-12 blossoms before or at the time of the emergence of the leaves. The foliage of elliptic, smooth, blue-green deciduous leaves turns attractive shades of purple in fall. Rich with strong cinnamon to clove fragrance, this Azalea is exceptionally cold-hardy and can withstand temperatures as low as -25ºF (-32ºC). A terrific landscape plant for northeastern gardens, this azalea has a marked tolerance to high pH.
Rhododendron prinophyllum is a native azalea that can be found from southwestern Quebec, through New England and northern Ohio, to the Appalachian Mountains at higher elevations.
