Climbing hydrangea

Climbing hortensias are healthy and strong, they are appreciated for their white ray flowers and the bright yellow autumn colour of their leaves. They're often used to green up facades and are particularly suitable for shady north walls, in streets with little sunlight, to hide downpipes etc... They are easy to care for, but they need, as the latin name suggests, a lot of water!

Requirements / Price

Location in partial or full shade with an acidic to neutral humose soil, always moist and even wet if possible (water regularly if needed). A compacted or calcareous soil is poorly tolerated. Planting distance between individual specimens: 1.5 to 4 meters. 

Caracteristics and Pruning

Climbing hydrangea are native to Japan and were introduced in Europe around 1830. Self-climber with adventive roots, that grows a little lower than in height than ivy: up to 6 meters or more. With a trellis it can be formed as semi-woody 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 and ray flowers as 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.

Growing aids on facades

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