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.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
