Climbing Hydrangea Vines for Sale Online Climbing Hydrangea Vines (Hydrangea anomala petiolaris) are a unique departure from the standard hydrangea. Large, fragrant clusters of creamy white flowers pop out of this twisting vine in May and June and are very attractive to wandering butterflies. No trellis is needed to grow this climbing vine, as it has the ability to cling to a concrete wall, tree, or almost any surface using its aerial rootlets. The Climbing Hydrangea flourishes in moist, acidic, well-drained soils but this resilient plant will tolerate dryer. It enjoys full shade but can tolerate up to full sun in cooler climates. In fact, it is the only climbing vine that blooms in the shade.This shade-loving plant can be slow to establish but don’t let it fool you; once a root system is developed, the vigorous climbing begins and it can cover your trellis or wall in no time. Flat-topped soft white flowering heads bloom in the summer to offer some shade.In the fall, this deciduous plant thins revealing the reddish-brown stems beneath and letting the sunshine through, which conserves energy and provides year-round interest. Or, if you so desire, you could train your Climbing Hydrangea to grow horizontal to become an extraordinary ground cover.
