Hydrangea 'Arbor Incrediball Storm Proof' is a deciduous flowering shrub. Produces the largest flower heads of any arborescens hydrangea — massive white globes that can exceed 12 inches across — on exceptionally strong stems that resist flopping even in wind and rain. Prefers organically rich, moist, well-drained soil. Most varieties perform best with morning sun and afternoon shade, though panicle types tolerate more sun. Among the most versatile and beloved shrubs for mixed borders, foundation plantings, cut flower gardens, and specimen use throughout the landscape.
