A genus of about four species of deciduous shrubs found in N. Asia. The three species cultivated are all beautiful white-flowered shrubs, allied to Spiraea, but differing in the larger flowers, and larger, bony fruits. They like a fairly rich soil and a sunny position. Propagation may be effected by means of cuttings made of rather soft wood and placed in brisk heat, but they do not root with certainty. The best way to raise young plants is from seed. Sucker growths sometimes appear at the base of E. racemosa, which can be separated with a piece of root attached, potted, and established in a little bottom heat. So far as is known, all thrive on chalky soils except E. racemosa.
