Native to Asia, Hydrangea anomala subsp. petiolaris (Climbing Hydrangea) is a vigorous, large, deciduous climber that clings by aerial rootlets along the stems. Masses of fragrant white flowers held in flattened clusters, up to 8 in. across (20 cm), appear in late spring to early summer. Resembling lacecap flowers, each cluster consists of tiny, creamy-white to greenish-yellow fertile flowers in the center surrounded by a ring of showy white sterile flowers. Unfurling in spring, the foliage of heart-shaped, shiny, rich dark green leaves, up to 4 in. long (10 cm), keeps its fresh look throughout the summer and turns golden-yellow in the fall. Exposed in winter, the trunk is equally attractive with its reddish-brown exfoliating bark on mature stems, adding a much-needed splash of color to the winter landscape. An extremely versatile vine with year-round interest that looks terrific climbing up a wall as it clothes it with its pretty foliage and delicate lacecap flowers. A very popular and elegant landscape plant.
