Description

Literally, a huge improvement over 'Annabelle'!

Our goal in creating Incrediball® hydrangea was to develop a non-flopping version of 'Annabelle.' What we ultimately selected, though, was even better: a powerhouse of a plant that not only has strong, sturdy, supportive stems, but also extra large flowers. On mature plants, they can become as large as basketballs! Blooms age to a beautiful jade green through summer and fall. Don't let its good looks fool you, though - this North American native is super hardy and tough as nails.

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.
