Hydrangea Seeds - Climbing Hydrangea
We have run out of stock for this item.
(Hydrangea anomala petiolaris) Perennial. Zones 4 - 7.
This garden classic is lovely in all seasons. In warmer months, showy white ombrells fill out your arbour, trellis or stone wall. In Winter, Climbing Hydrangea's bare branches are a mahogany that stands out when the world around is grey and white.
Although typically planted as a climber, Climbing Hydrangea can also work as a creeping ground cover and will do especially well on barren banks. This plant originates in the mountainous regions in China where is grows along river banks, cliff faces and other steep embankments.
Unlike twining vines, Climbing Hydrangea is safe to climb on trees. Aerial roots secrete a stick substance that adheres the vines to whatever it is climbing on. There is no danger of trees getting strangled by tendrils.
As a vine, Climbing Hydrangea can reach 40ft and as a sprawling ground cover it can cover up to 200 sq ft.
