White or Yellow mustard (blooms with yellow flowers) is often used as a green manure crop, but can also be used to harvest mustard seeds or as a sprout vegetable (entire year). Nice on sandwiches or in salads. Is part of the crucifer family and as a green manure crop can produce large amounts of organic matter in a short time. Often used on soil that is available late. After flowering mow well and work into the soil. Few soil requirements, although prefers soil that is not too acidic. Attracts many bees.
