Rosebay Rhododendron

Rosebay Rhododendron (Rhododendron maximum)

Rosebay Rhododendron (Rhododendron maximum), also known as Great Laurel or American Rhododendron, is a broadleaf evergreen shrub native to the Appalachian Mountains and Eastern U.S. woodlands. Known for its dense growth, leathery foliage, and showy late-spring blooms, this species brings year-round interest and habitat value to shaded landscapes.

Distinctive Features

Typically growing 8 to 15 feet tall and wide, Rosebay Rhododendron forms a dense, multi-stemmed mass of dark green, leathery leaves. In late June to early July, it produces clusters of bell-shaped white to pale pink flowers speckled with green or yellow markings. Its evergreen foliage and multi-season structure make it a staple in naturalized or woodland plantings. Bark is smooth and light gray on young stems, becoming slightly rough with age.
