Gorgeous arching sprays of white flowers in mid and late spring and toothed, bright green leaves.
This popular, deciduous shrub is ideal for a sunny, well-drained shrub or mixed border. Relatively vigorous and easy to grow, to guarantee an abundant, foam-like display it must be pruned annually immediately after flowering.
Immediately after flowering prune flowered shoots to strong buds. On mature specimens cut back between a quarter to a fifth of the old shoots to the base.
