Trifolium is a genus of flowering plants commonly known as clovers. It is composed of about 300 species of annual and perennial herbaceous plants in the legume family Fabaceae. The most widely recognized species is the white CLOVER, which is found in many lawns and pastures. Other species are used as forage crops, and some are cultivated as ornamentals. Trifolium is native to temperate regions of the Northern Hemisphere, but some species have become naturalized in other parts of the world.
