yellow sweet clover, Melilotus officinalis

Yellow sweet clover is sort of the good, the bad, and the pretty (cue Morricone's odd flute music?). It was brought here very early as a forage crop that also helps nuture the soil. But in moldy conditions it can become poisonous to cattle. But the poison has been used to control rodents. And yellow sweet clover is useful for remediation of soils containing dioxins. Yellow sweet clover can be seen in every state and province, and on GL and SPM. Lenawee Co MI, 6/9/21. Bean family, Fabaceae.
