I believe this is crown vetch. As we drove through the rural countryside, I saw this bush by a pasture. The plant looks like crown vetch, but crown vetch is supposed to be a ground cover, not a bush. Crown vetch was one of those "miracle" plants that was introduced to my country. This plant was supposed to be great to prevent soil erosion and to rehabilitate the soil. Instead, crown vetch became an invasive weed of all invasive weeds. The plant, especially the blossoms are beautiful. However, the beauty of this plant is countered by its invasive weed nature.
