Hydrangea anomala petiolaris

This vine has large, flat topped white flowers appearing in early summer. This vigorous growing, deciduous vine clings with aerial roots, allowing it to climb high with support.

Flowers in zone 7 are fully expressed by early May. Flowers are at their best in June and July further north.

BEFORE PLANTING: Keep in mind how big the shrub will be at maturity. Space your shrub away from your home a little over 1/2 the spread length. For instance: if your mature spread is 6' then plant it (at least) 4' from the base of your home.

Deer Resistant 

PRUNING CLIMBING HYDRANGEA:

If your climbing hydrangea doesn’t need pruning, just remove old, wilted blooms to keep the plant looking tidy.

Maintenance pruning: Cutting back hydrangea vines is best done immediately after flowering, before new buds appear. Otherwise, you risk cutting off flower buds that appear soon after flowering, thus drastically reducing development of new blooms for the upcoming year.

Winter-killed growth: Dead or damaged growth should be removed in early spring, when buds are appearing or just beginning to open. However, damaged growth can be removed as needed any time of year.

Staggered pruning for overgrown plants: If the climbing hydrangea vine is badly overgrown, reduce the size gradually by staggering the pruning over a span of two or three years.

Hard pruning of old or badly neglected plants: Old, neglected vines can be cut to the ground. This means you won’t enjoy blooms the coming season, but the rejuvenated plant should come back better than ever the following year.

How to Prune Climbing Hydrangea: Cutting back hydrangea vines is uninvolved; simply cut off wayward shoots just below spent blooms or at the point where the vine joins a larger stem. You can also cut off old or dead stems at the base of the plant to stimulate healthy new growth.

Always use clean, sharp pruners when cutting back hydrangea vines. Wipe the pruners with rubbing alcohol or a solution of bleach and water to kill bacteria.
