Invincibelle Sublime hydrangea (H. arborescens) ushers in a new day for full-sized smooth hydrangeas, with cloud-like mophead flowers floating above the plant on super-sturdy stems. Each floret of the big, fluffy blooms is a deeply saturated tourmaline-green that looks refreshing and intriguing in the garden all summer long. Very dark green foliage sets off the lively green of the blooms. Makes a fantastic cut flower, both fresh and dried, if you can bring yourself to remove them from the fabulous plant.

Soil Grows well in most soils; avoid wet and poorly drained sites. Mulch is recommended in the landscape.
Pruning Blooms on new wood - cut back by about one-third its total height in early spring, just as the new growth begins to emerge on the stems. Smooth hydrangeas may be cut back harder, however, this prevents woody cells from developing, prohibiting the plant from achieving its maximum stem strength.
Uses Versatile and showy, smooth hydrangeas offer dozens of landscape applications: foundation plantings, perennial gardens, hedges, cut flower gardens, naturalizing, pollinator and wildlife gardens.
Growing Tips We recommend full sun for smooth hydrangeas in the cooler end of its hardiness range; afternoon shade is a good idea in warmer climates, however. The flower color of smooth hydrangeas is not influenced by soil chemistry. Makes an excellent cut flower, both cut and dried.
