Incrediball Smooth Hydrangea
Hydrangea arborescens Incrediball®
Incrediball Smooth Hydrangea is a groundbreaking improvement on the classic 'Annabelle', engineered for unparalleled flower power and resilience. It produces colossal, perfectly round flower heads the size of grapefruits, starting with a lime-green tint before opening to pure, brilliant white. Its key triumph is an ultra-strong stem structure that stands firm, even after heavy rain, holding the massive blooms proudly upright without collapsing. Blooming on new wood and often reblooming later in summer, it delivers a clean, bold statement of purity and strength in the garden.
