Climbing Hydrangea

Climbing hydrangea

Hydrangea anomala subsp. petiolaris known as Climbing Hydrangea is considered the best of vines. This attractive climber grows a cinnamon exfoliating bark with deep glossy green foliage. It produces a waterfall of fragrant clusters of white flowers 6-10 inches wide attached to a 1 inch stalk making it a stunning vine when in bloom.

Plant in rich, moist, well-drained soil in full sun or shade. A North or East side of a building is preferred. In hotter climates provide more shade and moisture. Be sure to provide a sturdy structure for it to climb on.
Climbing hydrangea will be slow to establish the first year; the fibrous roots take time to recover from transplanting. During this time maintain even moisture and because of minimal growth feed it very little. Do not prune in the juvenile stage. Once established, it will take off and eventually grow 50-70 ft high and 30-40 ft wide. This vigorous climber will develop tenacious aerial roots that “cement” themselves to bark, brick, wood, vinyl siding which can be a problem when removing the vine. The residue left by the aerial roots is difficult to remove. Avoid planting against a Maple tree as it will compete for moisture.

When the vine reaches adult stage it will grow multi branched stems that produce flattened clusters of white flowers that change to light green with age. The vine blooms on old wood and can take 6-10 years to start blooming. It blooms in May thru July.
The vine can be pruned after flowering.

Propagation: Take cuttings in early spring when shoots are green and soft.
