About
Melilotus albus, known as honey clover, white melilot (UK), Bokhara clover (Australia), white sweetclover (US), and sweet clover, is a nitrogen-fixing legume in the family Fabaceae. Melilotus albus is considered a valuable honey plant and source of nectar and is often grown for forage. Its characteristic sweet odor, intensified by drying, is derived from coumarin.
Melilotus albus is of Eurasian origin but can now be found throughout the subtropical to temperate zones, especially in North America, and is common in sand dune, prairie, bunchgrass, meadow, and riparian habitats. This species is listed as an "exotic pest" in Tennessee, "ecologically invasive" in Wisconsin, and a "weed" in Kentucky and Quebec.
Where it grows
White sweetclover is native to much of Asia and southern Europe, from France and Spain to Kazakhstan and Myanmar, and also northeastern Africa.
Uses
White and yellow sweetclover are considered valuable honey plants, and the foliage and seeds are consumed by wildlife. They are frequently cultivated for livestock forage and as a cover crop.
