Shrub lespedeza is an erect, deciduous ornamental shrub from eastern Asia with pink-purple pea-like flowers in late summer, grown for its form and bloom. It is easy to grow in full sun but can become invasive in the southeastern United States, so choose a cultivar and monitor spread.

About
Lespedeza bicolor is a species of flowering plant in the legume family known by the common names shrubby bushclover, shrub lespedeza, and bicolor lespedeza. It is native to eastern Asia, ranging from southeastern Siberia to eastern China, Mongolia, Korea, and Japan. and it is widely grown as an ornamental plant. In some regions, such as the southeastern United States, it grows in the wild as an introduced and invasive species.
How to grow it
This species was first introduced to the United States as an ornamental shrub in 1856, and it was likely introduced several times after that. In the 1930s it was recommended for use as erosion control and in the revegetation of abandoned mine sites. It was used to enhance wildlife habitat, particularly for the northern bobwhite. The United States Department of Agriculture produced and distributed the seed and many millions were planted. A number of strains and cultivars were developed to improve the plant's drought tolerance and seed production.
Where it grows
It can grow in many types of habitat, including disturbed areas. By the 1990s the plant had escaped cultivation and taken hold in many regions of the eastern United States, especially those in the Southeast. In the US, it is now present from New York to northern Florida and as far west as Nebraska and Texas. It can be found as far north as Ontario in Canada.
