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.
