Introduced, warm-season, annual to short-lived
perennial, prostrate to sprawling legume. Stems are hairless to densely bristly. Leaves are
pinnate, with 20-50 leaflets, each 3-15 mm long. Flowerheads consist of clusters of 3-10 yellow pea-like
flowers in the leaf axils. Pods are divided into 3-7 segments and covered in dense soft or stiffly erect hairs. Flowers throughout the growing season. A native of North America, it is sown for grazing or as an orchard ground cover. Best suited to soils with a pH(Ca) greater than 5, an annual rainfall of more than 1000 mm and where moisture is retained. It is not very persistent on poor
country. A palatable and high quality feed, it produces
moderate yields under good conditions. Not very drought tolerant and is susceptible to
powdery mildew. Responds strongly to phosphorus applications, but will tolerate low fertility (although much lower
yielding). Tolerates heavy grazing and benefits from levels of grazing which reduce shading by grasses.
