Wow! What a bloom! This hydrangea produces a bevy of huge flower clusters (as much as 12" across) that are pure white, maturing to chartreuse. Unlike other Hydrangea arborescens, Incrediball™ has sturdy stems that keep the hefty flowers aloft. The mature flowers are superb for drying. Very cold tolerant and can be grown as far south as zone 9.
H. arborescens prefers full sun to partial shade. It will adapt to any soil type but grows best in humus-rich, moist, well-drained soil. Incrediball™ blooms on new wood so prune back in late winter to promote strong new growth and abundant flowers.
