Sweet clover, genus Melilotus, is a group of some 23 species native to Eurasia, in the pea family, Fabaceae. Two of them, yellow sweet clover, Melilotus officinalis, and white sweet clover, Melilotus albus, are found all over North America. They are weedy and often quite aggressive, building up large populations quickly. But they add nitrogen to the soil, are good forage for livestock, are a source of honey for bees, and more. They have both supporters and detractors.
