Create a lush woodland landscape with Rosebay Rhododendron (Rhododendron maximum), a hardy evergreen shrub prized for its glossy foliage and impressive late-season blooms. Native to eastern North America, this shade-loving species thrives in acidic woodland soils and brings year-round structure and beauty to naturalized gardens.

Rosebay Rhododendron typically grows 8–15 feet tall and wide, forming a dense, upright rounded shrub. In ideal woodland conditions, mature plants may grow even larger. Its large, leathery, dark green evergreen leaves provide four-season interest and make an excellent backdrop for companion plants in shaded borders.

In late spring to early summer, upright clusters of 15–30 funnel-shaped flowers bloom in shades of pale pink to nearly white, often accented with yellow-green spotting. These showy blooms attract hummingbirds and butterflies while adding brightness to shaded gardens. Exceptionally cold tolerant and long-lived, this shrub is perfect for woodland gardens, natural screens, foundation plantings, and mass plantings.
