Rosebay Rhododendron – Rhododendron maximum Shrub Seeds | 300 Seeds | Hardy Evergreen Woodland Shrub | Showy Shade Blooms

Enhance your woodland landscape with Rosebay Rhododendron (Rhododendron maximum), a hardy evergreen shrub native to eastern North America. Known for its large glossy foliage and impressive flower clusters, this shade-loving species brings year-round structure and late-season blooms to woodland gardens and naturalized spaces.

Typically growing 8–15 feet tall and wide, Rosebay Rhododendron forms a dense, upright rounded shrub that can create beautiful privacy screens in shaded settings. In ideal woodland conditions, mature plants may grow even larger. The leathery, dark green evergreen leaves provide four-season interest and contrast beautifully against its soft pink to nearly white blooms.

In late spring to early summer, upright clusters of 15–30 funnel-shaped flowers appear, often accented with yellow-green spotting. These showy blooms attract hummingbirds and butterflies and brighten shaded gardens when many other shrubs have finished flowering. Extremely cold tolerant and adaptable to woodland soils, this species thrives in acidic, humus-rich, well-drained soil with consistent moisture.

Perfect for woodland gardens, shade borders, foundation plantings, mass plantings, and natural screens.
