Hydrangea petiolaris


Climbing hydrangea

This deciduous, self-clinging climber from Japan and northeast Asia can reach heights of 15 metres or more, and bears beautiful lacy heads of small white flowers in summer. It has oval, finely toothed leaves.


Plants are very effective when encouraged to grow on the trunk of tall trees.


Plants must be grown in a shady or partly-shade position to avoid scorching of both leaves and flowers in the summer. Soil should be constantly moist and rich in humus, but must also be well drained. Plants will tolerate frost. Prune immediately after flowering, removing all stems that have just flowered. Propagate from cuttings in summer or seed in autumn. Watch for powdery mildew, leaf spot, honey fungus and aphids.
