A stronger, more spectacular take on the classic Annabelle hydrangea, Incrediball® Smooth Hydrangea delivers enormous, snowball-like blooms on sturdy stems that stay upright through summer rains. Starting mid-season, pure white flower heads open to impressive 10–12″ globes that later soften to a soft jade-green, remaining showy well into fall and even as dried blooms.
CareThis hydrangea thrives in full sun to part shade, performing best with six or more hours of sunlight for robust stems and abundant flowers. Plant it in moist, well-drained soil and protect roots with a 2-3″ layer of mulch to conserve moisture and moderate temperature. Whether temperate or cold, Incrediball® is a low-maintenance choice that tolerates USDA Zones 3-8 and resists flopping thanks to its strengthened stems. Pruning can be simple: simply cut back by about one-third in early spring to promote vigorous new growth and bigger flower heads. A light spring fertilizing with a balanced shrub or rose formula encourages seasonal performance. The optimum amount of sun or shade each plant needs to thrive: Full Sun (6+ hours), Part Sun (4-6 hours)
Growth HabitForming a neatly rounded, medium-sized shrub approximately 4-5′ tall and wide, Incrediball® blends structure with exuberant blooms. Its upright habit and bold form make it ideal as a standalone specimen, informal hedge, or mass planting. The spherical flower heads command attention in mixed borders, foundation plantings, and cutting gardens alike.
ToxicityLike most hydrangeas, all parts of Incrediball® Smooth Hydrangea are considered poisonous if ingested, so it’s best used where pets and children won’t nibble on foliage or blooms. Deer tend to avoid it, making it a practical option in deer-prone landscapes.
