Hydrangea anomala
Also called Japanese Climbing Hydrangea, Chinese Hydrangea
A woody, self-clinging climber from the Himalaya and China that covers walls and tree trunks with flat white flower clusters in summer. It grows slowly at first and settles in best in partial shade with cool, moist soil.
Hydrangea anomala, the Japanese climbing-hydrangea, is a species of flowering plant in the family Hydrangeaceae native to the woodlands of the Himalaya, southern and central China and northern Myanmar.
It is a woody climbing plant, growing to 12 m (39 ft) height up trees or rock faces, climbing by means of small aerial roots on the stems. The leaves are deciduous, ovate, 7–13 cm (2.8–5.1 in) long and 4–10 cm (1.6–3.9 in) broad, with a heart-shaped base, coarsely serrated margin and acute apex. The flowers are produced in flat corymbs 5–15 cm (2.0–5.9 in) diameter in mid-summer; each corymb includes a small number of peripheral sterile white flowers 2–3.5 cm (0.8–1.4 in) across, and numerous small, creamy-white fertile flowers 1–2 mm diameter. The fruit is a dry urn-shaped capsule 3–5 mm diameter containing several small winged seeds.
Hydrangea anomala is grown as an ornamental plant. The subspecies H. anomala subsp. petiolaris has received the Royal Horticultural Society's Award of Garden Merit.
