A better pink 'Annabelle' - type hydrangea! Meet Invincibelle® Spirit II hydrangea - an improved version of Invincibelle® Spirit, the original pink 'Annabelle' hydrangea. It delivers darker foliage, stiffer stems, and larger flowers of a deeper, truer pink. The blooms age to an attractive green instead of the bisque color of the original. This hydrangea grows from Manitoba to Mobile, blooming every year from mid-summer to frost. It is a strong rebloomer. $1 from each Invincibelle® Spirit II sold is donated to the Breast Cancer Research Foundation® (BCRF). We encourage you to donate as well. BCRF is dedicated to advancing the world's most promising research to eradicate breast cancer in our lifetime. Click here for more information about the Invincibelle Spirit Campaign for a Cure.

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.
