    • Why we like this plant

    • About this plant

      Hydrangea Incrediball is a remarkable variety of Hydrangea arborescens, bred for its enormous, round flower heads and robust, upright stems. Its blooms start off pale green, transitioning to creamy white in midsummer before fading back to soft green, creating a multi-seasonal display. Unlike 'Annabelle', this variety has much stronger stems, which help support its impressive 30cm-wide blooms, even after heavy rain. Its lush green foliage provides excellent structure, turning golden yellow in autumn. Ideal for mixed borders, feature planting, and even hedging, Incrediball is a hardy and low-maintenance shrub that thrives in sun or partial shade.
