Introduced. Biennial. Propagates by seeds. Time of bloom: June to October. Seed-time: August to November. Range: Throughout North America except the far North. Habitat: Roadsides and waste places; common about towns.

A smaller plant than the preceding species with stems two to five feet tall, slender, erect, with many spreading branches, the growing twigs finely hairy. Leaflets oblong-obovate, with rounded tips, edges finely toothed; petioles nearly as long as the blades. Flowers bright yellow, in long, one-sided, axillary racemes, the blossoms slightly larger than those of White Melilot but less fragrant, the standard and wings of nearly equal length; the plant often flowers a week in advance of its white sister and holds in bloom somewhat later, which wins for it the liking of bee-keepers. Pods ovoid, transversely wrinkled, net-veined, often slightly hairy, one- or two-seeded. (Fig. 166.)

Means of control the same as for White Sweet-clover.
