Climbing hydrangeas

Mature plants look spectacular in early summer when in full flower covered with white flowers that are produced on last year’s shoots. Though self-supporting, they benefit from having a structure such as trellis, to help them on the way.

They will grow well in most soils provided they are reasonably moist and fertile. Climbing hydrangeas grow well with a degree of shade, making them well-suited for east- and north-facing walls. They may be also grown in sunnier spot as long as the soil is not too dry. Hydrangea seemannii and H. serratifolia are less hardy and need shelter to thrive.

Climbing hydrangeas grown in very hot and dry spots are unlikely to thrive.

Climbing hydrangeas form aerial roots on stems that cling to a wall or a host plant.
