How to grow climbing hydrangea

When to plant climbing hydrangea

Climbing hydrangea is a large woody vine that clings by twining stems and disk-like aerial rootlets, bearing flat clusters of fragrant white flowers in late spring to early summer (NC State: summer). Plant in spring or fall in rich, moist, well-drained soil; it is slow to establish and can take several years to begin flowering, and it flowers best in dappled to partial shade.

Climbing Hydrangea is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
