Yellow Sweet Clover
Melilotus officinalis
Pea family (Fabaceae)

This native of Eurasia has, as the common name suggests, a sweet-smell. The leaves contain coumarin giving off the scent of fresh-mown pasture when dried. White Sweet-clover has been shown to be the same species as Yellow Sweet-clover. Melilotus officinalis is an important source for bees. The "officinalis" part of the name was given centuries ago because the plant was sold in "offices," i.e., apothecary stores that sold medicines. This plant was reputed to have medicinal properties.
