Description of Plant(s) and Culture

Yellow melilot is a biennial plant; the slender, branched, hollow stems, from 1 1/2 to 5 feet high, bear pinnate leaves (clover-like) with 3 obovate or oblanceolate leaflets, which are finely toothed and blunt-tipped. Blooming from June to November, the fragrant, light golden-yellow pea-like flowers grow in axillary racemes. Later, long crooked pods appear, they contain flat brown seeds. The plant is fragrant when crushed.

Another variety: White melilot (M. alba), a similar but taller, white-flowered species, has the same medicinal uses. Biennial, grows 1-9 feet tall, leaves clover-like; leaflets elongate, slightly toothed. Small white, pea-like flowers in long, tapering spikes, blooms April to October. Like yellow melilot, it is a very common plant in fields and waste places over most of North America and in Europe and Asia.
