Summary
Incrediball® produces massive white blooms on sturdy stems that remain upright throughout the season.
This improved smooth hydrangea was bred for stronger stems and larger flower heads than traditional selections. Blooms emerge creamy, transition to bright white, then mature to soft green, extending visual interest well into autumn.
Each rounded flower head is densely packed, creating a bold presence in foundation plantings and mixed borders. Flowers are long lasting and well suited for both fresh arrangements and drying.
Cold hardy and dependable, this native species performs consistently across a wide range of climates and soil types.
Care
Incrediball® Smooth Hydrangea Care
Plant in full sun to partial shade. Best flowering and strongest stems occur with at least six hours of sunlight daily.
Provide well-drained soil with consistent moisture. While adaptable, this shrub performs best in average garden soil that does not remain saturated.
Water regularly during establishment and during extended dry periods.
Prune between late fall and late winter while the plant is dormant. Smooth hydrangeas bloom on new wood, so dormant pruning will not remove upcoming flower buds.
A spring application of slow release fertilizer may support vigorous growth and abundant flowering.
Container Growing: Use a large container with adequate drainage and quality potting mix. Container-grown plants require more frequent watering than in-ground plantings. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
