Incrediball® Reblooming Hydrangea

Incrediball® Reblooming Hydrangea is Annabelle’s stronger, showier successor — the same beloved smooth hydrangea (Hydrangea arborescens) character in a dramatically improved form. Where Annabelle’s massive blooms tend to flop their stems in rain or wind, Incrediball® was specifically developed with strong, sturdy stems that hold those enormous 12-inch bloom heads upright through the season. Each flower head carries four times the individual florets of traditional varieties — creating the genuinely basketball-sized white globes that make this one of the most visually impressive flowering shrubs available. Lime green in bud, transitioning to pure white at peak, aging back to green in fall. Blooms on new wood, cold-hardy to Zone 3, and exceptional for fresh and dried arrangements. Butterfly attracting.

Basketball-Sized Blooms — Stronger Stems Than Annabelle

The bloom size is genuinely extraordinary — up to 12 inches in diameter, with four times the floret density of traditional Annabelle-type hydrangeas, creating flower heads so full and rounded they genuinely resemble basketballs at peak white. The stem strength improvement over Annabelle is equally important: Incrediball®'s robust stems hold those massive heads upright through rain and wind without the flopping that makes Annabelle so frustrating after a summer storm.

Lime Green to White to Green — A Changing Season-Long Display

The color journey adds months of visual interest. Blooms emerge lime green in bud — a warm, fresh color in its own right — then transition to brilliant white at peak bloom through mid-summer, then age gracefully back to green as fall approaches. That three-stage progression means the plant looks intentional and interesting throughout the blooming season rather than presenting a brief peak followed by obvious decline.

Blooms on New Wood — Prune in Early Spring

Incrediball®'s new-wood blooming habit is one of its most practically valuable qualities. Unlike blue or pink mophead hydrangeas that bloom on old wood and can be accidentally pruned into silence, Incrediball® blooms reliably on the current season’s new growth — cut it back hard in early spring and it responds with vigorous new stems loaded with blooms. No bloom-year guesswork, no worrying about winter kill eliminating next year’s flowers.
