Hydrangea anomala ssp. petiolaris var. ovalifolia is a climbing hydrangea, similar to H. anomala ssp. petiolaris but on a smaller scale. It will grow up trees, trellises or fences by means of aerial roots. Its outward-growing side shoots can be pruned back to maintain a neater shape. It can also be grown as an effective ground cover plant.
Propagate by layering. Using a half-straightened paperclip just pin down a stem showing development of aerial roots. Do not disturb for two or three months by which time the stem should have taken root and can be separated from the parent plant.
