Climbing Hydrangea

Hydrangea petiolaris (hy-DRAN-jee-ah pet-ee-oh-LAR-is)

Family: Hydrangeaceae Non-native Vine (vertical)

Climbing hydrangea has rich green foliage, mid-summer white flowers, yellow fall color, and striking exfoliating bark in winter. This vine is an early summer bloomer and is excellent for a massed effect on brick or concrete walls, arbors, gazebos, or almost any free-standing garden structure. It clings and/or climbs not only by twining but also by aerial rootlets. This woody vine has an almost shrub-like appearance due to its lateral branches and is native to wooded valleys, stream banks, and on rocky mountain slopes. Climbing hydrangea is somewhat slow to establish and slow to begin flowering after transplanting. It prefers rich, well-drained, moist soil, will grow in sun or shade, and can easily grow 60 to 80 feet. Once established, it has no serious pest problems. More information on Hydrangea .
