Melilotus Officinalis
Commonly known as Yellow Sweet Clover or Kingโs Clover, this tall, airy biennial is a staple of sunny meadows and roadsides. It is most famous for its intoxicating fragrance, which smells like a sweet blend of vanilla and freshly mown hay. While it is a beloved "pasture plant" that provides high-quality nectar for honeybees, it has a rebellious side, often spreading quickly where it isn't invited.
Yellow Sweet Clover is the scientific "ancestor" of modern blood-thinning medications! After researchers studied why cattle were mysteriously bruising after eating fermented clover, they discovered the compound that led to the creation of Warfarin, a drug used today both as a life-saving heart medication and a common rodenticide.
To grow Melilotus Officinalis, also known as yellow sweet clover, follow these steps:


Melilotus Officinalis prefers well-draining soil with a neutral to alkaline pH level. It grows best in nutrient-rich loamy soil that is moist but not overly wet. The soil should be loose, fertile, and full of organic matter. It can tolerate drought conditions but not waterlogged soils. Sandy loam soil is ideal as it provides good drainage and aeration. A soil mixture that includes equal parts of garden soil, peat moss and perlite can also work well. It is recommended to avoid heavy, compacted soils that can suffocate the roots and restrict growth.
Melilotus Officinalis plant can be propagated by taking stem cuttings in mid-summer. The ideal stem cuttings are approximately four inches long and should be stripped of any leaves from the bottom half. The cuttings should then be dipped in rooting hormone and planted in a well-draining soil mix. The soil should be kept moist and placed in a shaded area until roots have formed. New growth should appear within four to six weeks. Once established, the Melilotus Officinalis plant can be transplanted to its permanent location.
