Flowers white, 1⁄3 in. across, produced from July to September in rather compact, terminal panicles 4 to 6 in. long, covered with white, starry down; calyx and seed-vessel hairy; stamens glabrous.

Native of Japan; introduced in 1870. It is a very pretty shrub where it thrives, but it is not so hardy as C. alnifolia, although it will survive all but the severest winters near London. It is quite hardy in the Wild Garden at Wisley, where there are two specimens about 10 ft high which came through the winter of 1962-3 unharmed.
