ABSTRACT

The genus Spiraea, a member of the Rosaceae, is composed of some 100 species. Plants are deciduous shrubs native to the northern hemisphere of mainly China, the Himalayan regions, Russia, India, North America, Europe, and Japan. As ornamentals in the garden they flower with great freedom and are often very graceful in growth habit. Many make excellent low hedges. In some places, the reddish or rich brown stems of many spiraeas make excellent winter color.
