Climbing Hydrangea

Climbing hydrangea are healthy and strong, and are appreciated for their white-edged big flowers and the bright yellow autumn colour of their leaves. They are often used to green facades and are particularly suitable for shady north walls, in streets with little sunlight, to hide downpipes, etc... They are easy to care for, if only -- as the name suggests -- they are given plenty of water!

Requirements / Price

Location in partial or full shade with an acidic to neutral humic soil-- moist and even wet; if possible watered regularly. A compacted or calcareous soil (lime) is poorly tolerated. Distance between plants: 1.5 to 4 m. 

Characteristics and Pruning

Climbing hydrangea are native to Japan and were introduced to Europe around 1830. A self-climber with adhesive roots, that grows a little lower in height than ivy: up to 6 metres or more. With a trellis it can be formed as a woody shrub with a more orderly and less sparse appearance. The foliage lasts from April/May until the end of October. In June/July there are large flower umbels (heads) and ray florets like bright white stars. The foliage is pale yellow to golden yellow in autumn, with inconspicuous capsule fruits, decorative reddish brown shoots in winter. Pruning in spring promotes branching of the shoots.

Climbing Aids on Facades

Even though they have adhesive roots, climbing hydrangeas benefit from a trellis to support its frame and to ensure they won't fall from the facade. Choose a heavy trellis from the options in the table below, depending on the desired height for the plant.
