Rhododendron catawbiense ‘Scintillation‘, commonly known as Scintillation Hybrid Rhododendron, is a dense, broadleaf evergreen shrub known for its showy trusses of pink-lavender flowers. Blooming in mid to late spring, each dome-shaped cluster can contain up to 12-15 bell-shaped flowers. Its dark green, leathery foliage remains attractive year-round, offering excellent structure and color in the landscape.

Growing 5 to 6 feet tall and wide, this hybrid rhododendron is a reliable choice for shady borders, foundation plantings, and woodland gardens. Although beautiful, it is not a native species and provides limited ecological value when compared to native shrubs.
