Securigera varia (Linnaeus) Lassen
(Purple Crown Vetch)


Family: Fabaceae

Status: Exotic

Synonyms:
Coronilla varia Linnaeus

Securigera varia is easy to recognize in the field by virtue of its lavender umbels of papillionaceous flowers held up on peduncles. It is an herbaceous plant with pinnately compound leaves with leaflets that are obtuse to emarginate at the apex with a small apiculus. Several states consider Coronilla varia to be an invasive species. Many of these same states in years past used Securigera varia to stabilize roadside berms unaware of its tendency to take over. Securigera varia is not common so far in the Gila, but has been seen on Signal Peak along the dirt roadside.
