Incrediball® Hydrangea (Hydrangea arborescens 'Abetwo') is a hardy, North American native shrub famed for its massive, 10–12 inch, basketball-sized white blooms and superior, sturdy stems that do not flop like the classic 'Annabelle'. Growing 4–5 feet tall and wide, this fast-growing, Zone 3–8 shrub thrives in sun to part shade, blooming from summer to fall on new wood.
Key Care & Features
Light: Full sun to partial shade (4–6+ hours of sunlight is ideal for the strongest stems).
Water: Prefers consistently moist, well-drained soil; should not be allowed to dry out.
Pruning: Since it blooms on new wood, prune back by about one-third in late winter or early spring.
Blooms: Opens lime-green, matures to white, and ages to a light green in fall.
Uses: Excellent for hedges, mixed borders, and as cut/dried flowers.
