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. =Description= It is a vigorous woody climbing plant growing to 20 m height up trees or rock faces climbing by means of small aerial roots on the stems. The 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 corymbs 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 3–5 mm diameter containing several small winged seeds. =Growing Conditions= 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. =Varieties= =Uses= As a climber on walls and fences. =Maintenance= May beed cabling as the adhesive roots are weak. =Propagation= Stem and root cuttings seed. =Pests and Diseases= See [[ taxa level (family genus species variety) = large tree = small tree = large shrub = small shrub = ...
