Caragana arborescens
Also called Siberian Pea Tree, Siberian Pea Shrub, Siberian Peatree, Caragana, Black Karagana, Common Caragana, Pea Tree
Siberian peashrub is a hardy, fast-growing shrub or small tree from Siberia and northeast Asia, widely planted as a windbreak and hedge. It is grown for its tolerance of cold, drought and poor soil rather than for showy flowers.
Caragana arborescens, the Siberian peashrub, Siberian pea-tree, or caragana, is a species of legume native to Siberia and parts of China (Heilongjiang, Xinjiang) and neighboring Mongolia and Kazakhstan. It was taken to the United States by Eurasian immigrants, who used it as a food source while travelling west. In some areas of the United States it is considered an invasive species. Introduced on the Canadian prairies in the 1880s, the hardy caragana provided shelter-belts, wildlife habitat, nitrogen fixation, and windbreaks to prevent soil erosion and snow drifting.
Caragana arborescens can be grown as an ornamental plant and has been extensively used in windbreaks. It has an extensive root system, and can be used in erosion control.
