Climbing hydrangea (Hydrangea anomala petiolaris) is a woody vine that flowers in midsummer. The roots attach to wooden fences, trellises or brick. Proper site selection and plant care are essential to establishing this flowering vine.
Non-climbing hydrangeas produce blooms in blue or pink. Climbing hydrangeas produce creamy white to white blooms. They make for an excellent backdrop in any garden landscape.
Climbing hydrangea prefers well-drained soil in a location that receives partial shade. Water thoroughly after planting and during prolonged dry spells.
Do not prune the vine until it has started climbing and is well-established. After it's established, prune away dead or diseased stems in early spring.
Climbing hydrangea takes longer to bloom than other hydrangea varieties. However, once they begin blooming, they tend to grow and climb at a fast rate.
Climbing hydrangea won't thrive without good support during the growing season. Use garden stakes or trellises for this purpose.
Some varieties of climbing hydrangeas grow 60 to 80 feet high. However, regular pruning keeps this growing vine at a manageable height.
