Proven Winners® Incrediball® Hydrangea

The name says it all—Proven Winners® Incrediball® Hydrangea (Hydrangea arborescens 'Abetwo') lives up to its title with some of the largest, most jaw-dropping blooms in the garden world. This native Smooth Hydrangea cultivar was selected from the beloved Annabelle and improved upon with stronger stems and even more robust floral power!

Each basketball-sized mophead bloom can reach a full foot across, bursting into creamy green florets that brighten to pristine white through summer, before mellowing to a jade-green in fall. These enormous flowers bloom all summer and fall, making a dramatic display that keeps on giving—even into winter if you leave them standing for seasonal interest!

This deciduous shrub grows into a tidy, rounded form with dark green, textured foliage that sets off the voluminous white flowers like a pro. Standing 4–5 feet tall and wide, its strong, upright stems were bred to hold up those heavy blossoms—no flopping here!

As an easy-care shrub with resistance to powdery mildew, it offers both performance and beauty with very little effort on your part. This Proven Winners® variety truly earns its reputation for dependability, vigor, and eye-popping blooms!
