An erect or prostrate annual with weak roots, forming ground-covering colonies.
Flowers near ends of leafy branches, small, typical pea flowers, white and either pink or purple. Blooms July-October.
Leaves alternate, on stalks, trifoliate (3 leaflets in cloverleaf configuration), leaflets oblong, wider toward the notched tips, to ½ inch long. Edges of leaves with hairs. Stipules at base of leaf stalks broad, pointed, tan, conspicuous, lacking hairs. Hairs on stems point toward the tip of the plant, not the base.
Occurs along roadsides and railroads, fields, pastures, open woods, and glades. This Asian plant was introduced to North America to prevent erosion, to feed wildlife and livestock (as both pasturage and hay), and, since it is a legume, to add nitrogen to the soil.

|Germination||Pre-soak the seed for 24 hours in very warm water and then sow it in spring in a greenhouse or inside 1-2 mm deep.|
Keep the soil moist, germinate in warm place.
When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in individual pots in a frame. It can be difficult to get the cuttings through their first winter, it is best to plunge the pots in a bed of ashes in a sheltered border outdoors.
