Hydrangea Petiolaris

What is the plant

Hydrangea petiolaris is a vigorous woody climbing vine plant, growing to 30 to 50 ft (9 to 15 m) height and 5 to 6 ft (2 to 2 m) wide. It grows up trees and rock faces in its native Asian habitats, climbing by means of small aerial roots on the stems. The leaves are deciduous, ovate, 4–11 cm long and 3–8 cm broad, with a heart-shaped base, coarsely serrated margin and acute apex. The flowers are produced in flat corymbs 15–25 cm diameter in mid-summer; each corymb includes a small number of peripheral sterile white flowers 2.5-4.5 cm across, and numerous small, off-white fertile flowers 1–2 mm diameter. The fruit is a dry urn-shaped capsule 3–5 mm diameter containing several small winged seeds.

How to Care for the Plant

Water
Similar to other hydrangea plants, climbing hydrangeas like constantly moist soil—in fact, the Greek root hydr- in the name refers to water, while angeon comes from the Greek word for "vessel." They need to receive at least one inch of water weekly (via either rain or traditional watering methods), and can sometimes necessitate more if the weather is especially hot or dry.
Pruning
Once the plants are established, climbing hydrangea tends to be vigorous growers and may need pruning in summer to keep them under control, if desired.
Fertilizer
Fertilize your climbing hydrangea vine each spring before the leaves begin to bud—granular fertilizer with a high phosphorous count will help create beautiful blooms. You can also fertilize again after the flowers have bloomed in the summer, though it's not a must.
