Incrediball hydrangea is an improved version of the garden classic 'Annabelle' hydrangea, but with stronger, sturdier stems that don't flop over, and extra-large blooms.. White flowers begin to appear in mid-summer and open to enormous snowballs. They then age to a lush jade green, which persists through frost.
Landscapes, naturalizing, hedges, perennial gardens. Also makes a very dramatic cut flower.
For the biggest, most abundant blooms and strongest stems, plant where it gets at least six hours of sun each day (warmer climates can get away with a bit less). A good layer of shredded bark mulch helps minimize water loss.
As for pruning, cut the entire plant back by about one-third its total height each spring, just as the new growth begins to emerge on stems. This serves to build up a strong, supportive, woody base while also encouraging abundant new growth for plenty of flowers.
If you wish to fertilize, an application of a rose fertilizer in early spring, once the soil has thawed, is sufficient.
