Planting Notes:

Difficult to establish. However, once roots become well established, growth is quite vigorous.
Requires well-drained soil. Water thoroughly until established.
Eastern or northern exposures will provide protection from harsh winter winds, as well as, hot, dry summer conditions.

Provide sturdy support for this vine which clings and climbs with its root-like projections.

Alternatives:

Consult local sources, including historic or public gardens and arboreta, regarding cultivars and related species that grow well in your area.

Related species:
HYDRANGEA ANOMALA differs in leaf size and flower clusters, which are smaller and appear to be floppy. Probably not as hardy as the subspecies PETIOLARIS.

Comments:

An excellent landscape vine with very showy, flat-topped flower clusters in summer.
A wonderful choice for climbing on brick and stone buildings.
HYDRANGEA PETIOLARIS is this plant's previous name and it will probably be known as such for many years to come.
