Growing Hydrangea - Vine Type
Latin Name Pronunciation: hye-dran'jee-uh
Hydrangea anomala petiolaris is one of the best of the ornamental vines and useful because it will grow and flower even in a northern exposure. This is a large heavy vine that requires a very sturdy support. Reddish brown, peeling bark is attractive in the winter. Superb growing up the trunk of large shade trees, walls, fences, or along a stone wall.
CULTURE
- Full sun or shade; needs afternoon shade in the Deep South and in western Zones 9 and 10.
- Plant in rich, moisture-retentive, well-drained soil.
HABIT
- Climbing Hydrangea's growth habit is unusual for a vine, because plants have lateral branches that will grow out as much as 3′ from the supporting structure, giving a rich, deep texture that is quite unlike that of other vines, which more typically twine up a narrow support.
- Climbs with the aid of rootlike holdfasts, which cling to almost any surface.
GROWTH
- Slow growing for first 2 or 3 years, but vigorous and fast growing once established (this is an example of that old gardener's saying about vines: first it sleeps, then it creeps, then it leaps. A little patience will be amply rewarded.).
- May take 3–5 years to start blooming.
- Prune as needed after bloom.
