Massive white flower heads the size of a basketball, held upright on sturdy stems that don't flop after a summer rain.

The Incrediball® Hydrangea (Hydrangea arborescens 'Abetwo') is a supersized improvement on the beloved 'Annabelle' smooth hydrangea. From summer into fall it produces giant rounded blooms that open soft green, mature to clean pure white, and fade to an antique green you can leave standing for late-season interest. The flowers ride on notably stronger stems than older smooth hydrangeas, so the show stays upright instead of sprawling. With a rounded 4 to 5 foot habit and bright green foliage, it reads as a lush, dependable anchor in the landscape from June through the first frosts.

Why growers choose the Incrediball® Hydrangea

• Enormous blooms. Flower heads can reach the size of a basketball, far larger than the classic 'Annabelle' they were bred from.
• Stems that stand up. Thick, rigid stems were the whole point of this selection, so the heavy heads resist flopping even after rain or wind.
• Reliable color, no fuss. Blooms shift green to white to soft chartreuse on their own — smooth hydrangeas don't change with soil pH, so the white is consistent every year.
• Genuinely cold-hardy. Rated for zones 3 to 8, it shrugs off harsh winters that would damage bigleaf types.
• Dependable bloomer. Because it flowers on new wood, a late frost won't cost you the season's show the way it can with old-wood hydrangeas.

Use it as a foundation planting, a flowering hedge along a walk or property line, or the backbone of a mixed border. The big white globes are excellent for fresh or dried cutting, and they brighten part-shade spots where other shrubs sulk.
