This shrub is a native of North China, belonging to the Spiraeas, and is sometimes named Spiraea grandiflora. Its habit of growth resembles the Philadelphus and it should group well with the members of that family. It opens its handsome white clusters early in June, remaining in flower about one month.

Propagate by cuttings of the ripe wood placed in sandy soil in the open border in November, or by suckers formed at the base of the plants in Winter, or by layers in the Fall, or by seeds sown one-eighth of an inch deep in the open ground as soon as ripe in the Fall.
