Any of an Old World group of low-growing leguminous plants (see legume), usually with leaves consisting of three leaflets and small flowers in dense heads. Sweet clover refers to various species belonging to the related genus Melilotus. (True clover genus Trifolium, family Leguminosae.)

Red clover (Trifolium pratense) and white clover (T. repens) now grow widely in the US. The most common honey is made from clover and the most important source of fodder is red clover.
