An excellent biannual for addig nitrogen. Very good forage for bees. Usuable for hay, but more woody than Yellow Sweet Clover.

Widespread usage as pasture, hay and cover crops has allowed this lovely plant to escape into the wild. It's a polite weed that does not tend to choke out it's neighbors and bees and insects adore it.

Widly used for honey production, and useful for adding nitrogen to the soil, it is one of the good guys you see along the roadsides.
