Japanese spiraea

Rosales > Rosaceae > Spiraea japonica L. f.
Japanese spiraea is a small, deciduous shrub up to 6 ft. (1.8 m) tall that invades a variety of habitats throughout the eastern United States. The alternate leaves are oval to lance shaped, toothed along the margins and 1-3 in. (2.5-7.6 cm) long. In late spring white to pink flowers occur in clusters at the tips of branches. Japanese spiraea invades a variety of habitats including fields, forests, stream banks and many disturbed areas. Once established, it can form dense stands which displace native vegetation and close open areas. Japanese spiraea is native to eastern Asia and was first introduced into the United States around 1879 as an ornamental.
