Caragana arborescens |
Caragana arborescens, the Siberian peashrub,[2] Siberian pea-tree,[3] or caragana, is a species of legume native to Siberia and parts of China (Heilongjiang, Xinjiang) and neighboring Mongolia and Kazakhstan.[4] It was taken to the United States by Eurasian immigrants, who used it as a food source while travelling west.[citation needed] In some areas of the United States it is considered an invasive species. Introduced on the Canadian prairies in the 1880's, the hardy caragana provided shelter-belts, wildlife habitat, nitrogen fixation, and windbreaks to prevent soil erosion and snow drifting.
