Incrediball® Hydrangea (Hydrangea arborescens ‘Abetwo’) – Proven Winners®

Incrediball® Hydrangea is a Proven Winners® selection known for its exceptionally large, globe-shaped white blooms and strong, upright stems. This cultivar of Hydrangea arborescens was bred for improved stem strength and flower size compared to traditional smooth hydrangeas, making it a standout flowering shrub in landscape design.

This deciduous shrub forms a rounded growth habit and produces massive flower heads that can reach up to 12 inches across. Blooms emerge green, mature to bright white, and often age to soft green tones later in the season, providing extended visual interest from early to late summer. The sturdy stems help support the oversized blooms, reducing flopping even after heavy rain.

Incrediball® Hydrangea is widely used in foundation plantings, mixed borders, and as a focal shrub in garden beds. Its reliable blooming on new wood makes it a dependable choice for colder climates, as it flowers regardless of winter dieback. It is also valued for cut flower use, both fresh and dried.
