Introduced winter annual and herbaceous legume. The leaves and stems of crimson clover resemble those of red clover, but the leaves are round-tipped and there is more hair on the stems and leaves. Seedlings grow rapidly from the crown and form a rosette. This enlarges as weather becomes more favorable. In the spring, the flower stems develop rapidly and end their growth with long, pointed conical flower heads comprised of 75 to 125 florets. Florets are a bright crimson color and open in succession from the bottom to the top.
