Incrediball Smooth Hydrangea

Hydrangea arborescens 'Abetwo', commonly known as the Smooth Hydrangea, is a cultivar that features large, showy clusters of white flowers that bloom from late spring to summer. The flowers start off as pale green before turning pure white as they mature, creating a soft, luminous effect. These blooms are arranged in rounded, flat-topped panicles that provide a substantial visual impact without overwhelming the garden.

Design tip

The exceptionally large flower heads give ‘Incrediball’ considerable visual weight. Repeat the shrub at intervals through a border rather than concentrating several together, creating a strong rhythm while allowing each rounded floral display enough visual space.
