Size and Method of Climbing:

Japanese hydrangea vine is a clinging vine that climbs by means of small aerial roots. Will grow to 15-30 feet. 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.

Native geographic location and habitat:

It is found in the woods and forests of the mountains of Japan.

Bark color and texture:

This vine attaches by root-like, cinnamon-brown holdfasts. Stems are cinnamon brown with flaky, peeling bark. They remain flat and do not protrude outward from the growing site.

Leaf description:

Leaves are 2 to 5 inches long, opposite, simple, coarsely toothed, oval to broadly heart-shaped. Dark green leaves turn a yellow fall color. Leaf stalks are red.

Flower description:

It has a single, 8 to 10 inch, flat-topped flower cluster (lacecap) composed of numerous fertile flowers surrounded by tear drop-shaped sterile outer petals (sepals). Flowers are slightly droopy. They appear in late June to early-July and last for around four weeks. This vine flowers on old wood.

Fruit description:

The fruit is a dehiscent capsule that is  not ornamentally important.

Plant care:

Japanese hydrangea vine is not a hydrangea, but is closely related to the climbing hydrangea (Hydrangea petiolaris). It grows in full sun, partial shade, or full shade but seems to do best in partial shade. It is tolerant of well-drained moist, humus-rich soil and 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.

List of pests, diseases, and tolerances:
