Rhododendron vaseyi (Pinkshell azalea)
Cressler, Alan

Rhododendron vaseyi

Rhododendron vaseyi A. Gray

Pinkshell azalea, Pink-shell azalea

Ericaceae (Heath Family)

Synonym(s): Biltia vaseyi


USDA Native Status: L48 (N)

A 5-15 ft. shrub with a slender-stemmed, open habit. The flowers are distinctive in that they appear before new leaves show either in the forest or on this azalea. Flowers lack the tube of most azaleas, so petals seem separate. Flowers color ranges from pink to pure white with a yellow throat. Medium-green foliage turns light- to dark-red in fall.

Pink-shell will not hybridize with other Rhododendron species. It is intolerant of drought.
