With its distinctive, rounded flower clusters, Hydrangea paniculata 'Powerball™' brings big summer color to your landscape while keeping the toughness and reliability of panicle hydrangeas. You get sturdy stems, strong branching, and full blooms that open creamy white and often take on soft pink tones as the season progresses.
Plant it where you can enjoy the blooms up close: near an entry, along a walkway, or as a focal point in a mixed foundation bed. At maturity it typically reaches 36-72 inches tall and can spread about 36-72 inches, so give it room to fill out or use it as a repeating shrub for a clean, rhythmic border.
For best performance, grow it in full sun to part shade. In hotter climates, a bit of afternoon shade helps keep the plant looking fresh, while brighter light generally improves flowering and stem strength. Water regularly the first season to establish a deep root system, then keep the soil evenly moist during extended dry spells, especially while it is setting buds and blooming.
Like other panicle hydrangeas, it blooms on new wood, so you can prune in late winter or early spring before growth begins. A light shaping prune maintains a rounded habit; a slightly harder prune can encourage larger blooms, but avoid removing too much if you prefer a fuller plant. Mulch to moderate soil moisture and protect roots, and enjoy the dried blooms for fall and winter interest.
