Hydrangea 'Pinky Winky Tree Form' is a deciduous flowering shrub. Produces spectacular, elongated cone-shaped flower heads with a distinctive two-toned effect — white flowers at the tip deepening to pink toward the base — an increasingly dramatic bicolor display. 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.
