Clusters of fragrant light pink to white flowers open in spring before the leaves fully emerge, so the bloom sits on bare stems where nothing competes with it. Rhododendron periclymenoides is a native deciduous azalea growing 6 to 8 feet tall and wide in full sun to part sun, hardy from Zone 4 through Zone 8.
The flowers are narrow-tubed with long protruding stamens, giving them a spidery look, and the fragrance is light and sweet.
Hummingbirds and butterflies come to them, and bees feed on the flowers through the bloom. This is one of the earliest nectar sources available in a woodland planting.
Pinxterbloom grows wild in moist woods, along stream edges, and in swamp margins across the eastern states, so it handles wet ground and part shade. Acidic soil is necessary, roughly pH 4.5 to 6.0, and it spreads slowly by runners into a loose colony.
