"Lotus corniculatus," Wikipedia, the free encyclopedia. Lotus corniculatus is a common flowering plant in the pea family Fabaceae, native to grassland in temperate Eurasia and North Africa. Common names include common bird's-foot trefoil, eggs and bacon and just bird's-foot trefoil, though the common name is often also applied to other members of the genus. It is also known in cultivation in North America as bird's-foot deervetch. The height of the plant is variable, from 520 cm, occasionally more where supported by other plants; the stems can reach up to 50 cm long. It is typically sprawling at the height of the surrounding grassland. It can survive fairly close grazing, trampling, and mowing. It is most often found in sandy soils. It flowers from June to September.
