May-June flowering. A fantastic, deciduous shrub which has a long period of interest, with the large, lace-cap white flowers held on tiered branches, giving the effect of snow and the medium-sized green leaves giving amazing autumn colours. The tiered branches are a real structural feature during winter and to some degree during the summer. Will grow in sun or semi-shade in most garden soils. 3 x 4.5m (10 x 13ft)
