Synonym(s): birdfoot deervetch

Birdsfoot trefoil is a low-growing, perennial forb with stems that can reach 2 ft. (0.6 m) long. Leaves are compound (with 5 oval to linear leaflets), stipulate and alternate. Leaflets (upper 3) are 0.5 in. (1.3 cm) long and less than 1/8 in. (0.3 cm) wide; the lower two resemble leaf-like stipules. Flowering occurs from May to August, when yellow, sweet pea-like flowers develop. Flowers develop in clusters of 2-8 on a long peduncle (stalk). Fruits are pods that occur in head-like clusters. Each pod is brown to black, cylindrical, 0.6-1.4 in. (1.5-3.5 cm) long, contains up to 49 seeds and has a persistent style at the apex. Birdsfoot trefoil is native to Eurasia and North Africa and occurs in pastures, roadsides, wetlands, disturbed grasslands and riparian areas.
