bird's-foot trefoil

Perennial, spreading, herbaceous legume (Lotus corniculatus) native to Europe and Asia but introduced to other regions. The stem grows to about 2 ft (60 cm) long. Its leaves consist of three oval leaflets, broadest near the tip. The yellow flowers (sometimes tinged with red) grow in clusters of 5 to 10. Often used as forage for cattle, it is occasionally a troublesome weed.
