An evergreen shrub known for its spreading, low-to-medium rounded habit and clusters of lavender-pink flowers that bloom in late spring, attracting pollinators. Its glossy green foliage provides year-round interest, making it an excellent choice for foundation plantings, borders, or woodland gardens.
Valued for showy blooms, evergreen foliage, and adaptability, it grows best in partial shade and prefers acidic, well-drained soil rich in organic matter. Light pruning after flowering helps maintain shape and encourages healthy growth. Winter protection is recommended in harsher climates: mulch around the root zone and shield foliage from cold, drying winds to prevent winter burn.
