Pink Diamond Panicle Hydrangea

Hydrangea paniculata ‘Interhydia’ (Pink Diamond) is a deciduous shrub valued for its large upright panicles of creamy white flowers that gradually deepen to clear pink and rosy tones as the season progresses. This panicle hydrangea blooms on new wood from mid to late summer, producing abundant flower heads on sturdy upright stems. Its dependable bloom display and strong color transition make it a classic garden cultivar.
