INCREDIBALL® Smooth Hydrangea

Zone: 3, 4, 5, 6, 7, 8 Exposure: Full Sun, Part Sun Height: 4-5' Width/Spread: 4-5'

Impressive. The massive white Blooms on Incrediball® smooth hydrangea are held aloft on extremely strong stems. Not a flopping flower to be found! These basketball-sized blooms open green, quickly turn white, and slowly mature to rich jade green. It isn’t only an improvement over the original ‘Annabelle’ for its massive flowers, but for its performance as well! These stems are so strong that they’ll hold up the dried flowers all winter long, providing an interesting view when the days are dreary. Come early spring, all you’ll have to do is give it a light trim, taking off just one-third of its height and width. And with that simple task done yearly, it’ll perform like a champion! Looks lovely as a foundation planting, in mixed beds, and when planted en masse it’s hard to look away from!

Why grow Incrediball® smooth hydrangea?

  • Tons of extra large flowers.
  • Easy care regimen.
  • Very cold hardy, will grow in a range of locations!


Light: It depends on the climate you live in. For gardens at the cooler end of their hardiness range, they will thrive in full sun. For gardens at the warmer end of the range, it benefits from placement in afternoon shade.

Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. Soil pH does not affect flower color.

Water: Average water needs.

Fertilizing: Nothing special required. If desired, you may apply a granular fertilizer formulated for flowering woody plants in late winter/early spring when the soil is workable.

Pruning: Pruning is recommended in early spring. When the buds begin to swell noticeably, cut the whole plant back by one third. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time, just cut back to a set of leaves!

Other: It can be used as a cut flower! For its longest vase life, cut vertically up the stem about 2 inches. This will help it absorb more water.
