Medicago lupulina Seeds: Black Medick / Yellow Trefoil

Medicago lupulina, also known as Black Medick, Yellow Trefoil, or simply Lupulina, is a versatile, hardy legume prized in agriculture and ecology. These small, black kidney-shaped seeds grow into low-lying plants with clusters of bright yellow flowers that draw pollinators while improving soil health through natural nitrogen fixation.

Medicago lupulina is a versatile legume used for soil improvement and as a green manure crop. It’s a short-lived plant, often acting as an annual or biennial, but its ability to readily reseed can make it appear perennial. Its low growth habit makes it suitable for undersowing in cereal crops and for suppressing weeds.
