This aggressive rhizomatous plant from Mediterranean Europe has become widely sown for stabilizing ground in eastern states, especially along newly constructed roads. In Ky. some records may be from persistent plantings, but the species does often spread by seed as well as rhizomes. Although it has been generally known as Coronilla varia L., the segregated genus Securigera has become widely applied in recent years (K, W). The species can form good forage for ruminants but not horses and perhaps rodents (due to toxic nitrogenous cardiac glycosides); there should to be more experimental use of livestock for reduction in North America (Tu et al. 2003).
