The Story

Features flattened clusters (corymbs) of fragrant, white flowers, heart-shaped dark green leaves, and attractive reddish-brown exfoliating bark. Slow to establish but will eventually cling to and climb masonry walls, arbors, and trees. The showy flower clusters consist of small, fertile inner flowers and larger, sterile outer flowers. Provides multi-season interest with flowers, foliage, fall color, and winter bark.
