'''''Hydrangea petiolaris''''' is a species native to the woodlands of [[Japan]], [[Korea]] and [[Sakhalin]] in easternmost [[Siberia]].
It is a vigorous woody climbing plant, growing to 20 m height up [[tree]]s or [[cliff|rock faces]], climbing by means of small aerial roots on the stems. The [[leaf|leaves]] are [[deciduous]], ovate, 4-11 cm long and 3-8 cm broad, with a heart-shaped base, coarsely serrated margin and acute apex. The [[flower]]s are, produced in flat [[corymb]]s 15-25 cm diameter in mid-summer; each corymb includes a small number of peripheral sterile white flowers 2.5-4.5 cm across, and numerous small, off-white fertile flowers 1-2 mm diameter. The [[fruit]] is a dry urn-shaped [[capsule (fruit)|capsule]] 3-5 mm diameter containing several small winged seeds.
It is sometimes treated as a [[subspecies]] of the closely related ''[[Hydrangea anomala]]'' from [[China]], [[Myanmar]], and the [[Himalaya]]; that species differs in being smaller (to 12 m) and having flower corymbs up to 15 cm diameter. The common name [[Climbing hydrangea]] is applied to both species.
===Cultivation and uses===
''Hydrangea petiolaris'' is grown as an [[ornamental plant]] in Europe and North America, where it is grown either on walls or on trellises or fences. Its clinging rootlets are not as strong as most other wall-climbing vines, and so is often anchored artificially.
