If you want huge, long-lasting white blooms without fussy care, Hydrangea arborescens 'Incrediball®' (Smooth Hydrangea 'Incrediball®') is an easy choice for the landscape. It forms a sturdy, rounded shrub with large, globe-shaped flower clusters held on strong stems for reliable summer color and great cut or dried arrangements.
Place it where you can keep the soil evenly moist, especially during hot, dry stretches. It performs best in partial shade, but it can handle full sun when you provide consistent moisture. Plant in well-drained soil enriched with organic matter, and mulch to help conserve moisture and moderate soil temperatures.
This smooth hydrangea blooms on new wood, so you can prune it with confidence. In late winter or very early spring, cut back as needed to refresh the plant and encourage vigorous new growth that supports the biggest blooms. Remove any weak or damaged stems to keep the shrub upright and full.
Use it in shrub borders, mixed plantings, rain garden edges, or as a low flowering hedge. Give it room to mature, and enjoy a dependable display that returns year after year with minimal maintenance.
