help Crown Vetch FAQ
What is crown vetch?
Crown vetch is the perennial legume Securigera varia, formerly often called Coronilla varia. It has trailing or scrambling stems, pinnately compound leaves, and clusters of pink to white flowers.
Why was crown vetch planted along roadsides?
Crown vetch was widely planted for erosion control because its spreading rhizomes can cover soil and stabilize slopes. Those same rhizomes can help it persist and spread beyond places where it was planted.
Does crown vetch have tendrils like a pea?
No. Its leaves are pinnately compound, but they do not end in the tendrils typical of many climbing peas and vetches. The stems spread or scramble instead.
Is crown vetch native to North America?
Crown vetch is Eurasian and has been introduced widely elsewhere, including North America. Its use as a ground cover has allowed it to become invasive in some habitats.
