Clover or trefoil are common names for plants of the genus Trifolium consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. Several species of clover are extensively cultivated as fodder plants. The most widely cultivated clovers are white clover, Trifolium repens, and red clover, Trifolium pratense.
