Size and Method of Climbing

A 15 to 30 feet high climbing vine.  Japanese hydrangea vine is a clinging vine that climbs by means of small aerial roots. 

Clinging vines attach themselves directly to a surface by means of holdfasts (adhesive discs) or by small aerial roots.  This type of vine grows best on a flat surface, such as stone, masonry walls and wood.

Plant Care

Japanese hydrangea vine is not a hydrangea, but closely related to climbing hydrangea (Hydrangea petiolaris). 
It grows in full sun, partial shade, or full shade but seems to do best in partial shade.
Tolerant of well-drained moist, humus-rich soil. Tolerant of drought once established, but intolerant of wet sites.
Plants are slow to establish but will grow more rapidly with age. May take several years to flower.
