Yellow Melilot

Some 20 species of annuals, biennials, and short-lived perennials belong to this genus, which spans Eurasia, N Africa, and Ethiopia. Melilotus officinalis, found in fields and on waste ground, is widely cultivated for hay, silage, and green manure, and makes an attractive addition to the wildflower meadow. It contains coumarins, which release the pleasant smell of new-mown hay when drying. Poorly dried or fermented melilot produces dicoumarol, a potent anti-coagulant, which is extremely poisonous; it is used in rat poison. Melilot effectively draws out toxins and reduces inflammation; melilot bandages were used from ancient Greek times until the 19th century for this purpose. Melilotus comes from the Greek meli, "honey", and lotos, "fodder", or "clover", because these plants are important sources of nectar and animal fodder.

Sweet Clover, found throughout much of North America, produces sweet, vanilla-scented yellow blooms on spikelike stalks. It contains small amounts of coumarin, an ingredient in prescription blood thinners, and has been used to improve blood circulation, heal wounds, and treat varicose veins and hemorrhoids.

Upright or spreading biennial with ribbed stems and trifoliate, toothed leaves, divided into oblong-elliptic leaflets, to 3cm (1½in) long. Yellow, honey-scented flowers, to 7mm (¼in) long, appear in slender racemes in summer, followed by brown, hairless pods.
