I couldn’t wait to plant white hydrangeas across the front of our white cottage after removing boxwoods. Proven Winners boasted about their large white blooms on their Incrediballs. One would think these flowers would stay white most of the summer before fading to green. This is my third year with these hydrangeas. Each year these blooms have faded to green in June. This year we have had a very cool rainy spring/early summer for Tennessee. My hydrangeas started out beautiful! I thought this is the year they will retain their white blooms! But NO!!! Just like other years not two weeks after my flowers were in full bloom they have already faded to green by June 20th. Don’t waste your money if you want white blooms. I do not understand how this company can claim this is a proven winner, it’s anything but.

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.

Also makes a very dramatic cut flower.
Maintenance Notes: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.
