A deciduous Heather Family shrub with spreading branches,this azalea may go unnoticed until the blossoms open. Then the shrub is transformed into a mass of white, particularly on open, moist slopes in the subalpine zone.

The white flowers are borne in clusters below new growth. They are somewhat bell-shaped and nearly an inch wide.

Although this rhododendron achieves its largest form in open habitat, it is also seen in forest settings and alongside trails. This is variety albiflorum.
