Noted for its upright stems that do not flop, Hydrangea arborescens Incrediball® (Smooth Hydrangea) is both a reliable and gorgeous flowering shrub. In early summer, this compact, deciduous shrub produces huge, rounded flower clusters, up to 12 in. across (30 cm), that brighten shady areas and bring life to the garden. Blooming for up to two months, the blossoms open lime-green, mature to brilliant white, then back to pale green in late summer before switching to a tan shade in fall. They contrast nicely with the foliage of large, ovate, dark green leaves. Incrediball is an improved version of the popular Annabelle hydrangea, with strong, sturdy stems that do not flop over and extra-large blooms. Incredibly hardy, even in the harshest winters, this US native hydrangea is perfect for mixed borders, small gardens and patio containers. The flowers make great cut flowers, fresh or dried.
