Black Mustard Overview
Black Mustard is known as Brassica nigra. It is an annual herb that can be grown easily and is famous as a spice and for large fields of pretty yellow flowers. Although all parts of Black Mustard are edible, it is cultivated mainly for its seeds. It belongs to the same family as broccoli and cabbage. In vineyards, mustard is planted as a cover crop that sterilises the soil from plant patogens. This plant grows up to 2m and is multi-branched. The lower leaves are toothed, deeply lobed, and are often hairy on the underside. Upper leaves on flowering stems are narrow, slightly waxy and egg-shaped. Black mustard seeds have the strongest pungent taste, but almost no aroma.
