Yellow sweetclover is an annual to short-lived perennial herb native to Eurasia. Plants can grow to approximately 6.5 ft. (2 m) in height and can sometimes be woody at the base. Leaves are ovate to oblong, entire, stipulate and 0.4-1 in. (1-2.5 cm) long. Flowering occurs from April to September, when yellow, pea-like flowers develop in a branched inflorescence at the tips of the flowering stems. Flowers are less than 0.25 in. (7 mm) long. Fruits are small, circular, wrinkled and light brown pods that contain one seed (rarely 2). Plants occur along roadsides, in open fields, pastures and other disturbed areas. Yellow sweet clover was introduced into North America as a forage crop in the 1900s. |
