Hairy Vetch
Vicia villosa
Family Fabaceae
Grown as an annual
A top overwintering green manure — fall-sown, it survives the cold, then in spring fixes a big nitrogen boost and smothers weeds before you crimp it into a no-till mulch (the classic bed for spring tomatoes). Its purple flowers feed bees. Usually paired with cereal rye. Terminate at bloom before it sets seed, or it self-sows.
