Hydrangea arborescens (Smoothleaf Hydrangea)
Color Name: Incrediball®
Super-sized flowers! Incrediball hydrangea will make you say WOW - it's an improved version of the garden classic 'Annabelle' hydrangea, but with strong, sturdy stems that don't flop over and extra-large blooms to boot. White flowers begin to appear in mid-summer and open to enormous snowballs, nearly the size of basketballs! They then age to a lush jade green, which persists through frost. It's a super easy, super reliable North American native that grows in chilly USDA zone 3 all the way up to USDA zone 8/9. Plant Incrediball hydrangea in your landscape and find out for yourself just how big, beautiful, and rewarding it can be.
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.
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.
