Mustard (Eng.), Swart Mostert (Afr.)
Black mustard is an ancient 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 sterilise the soil from plant patogens. The plant grows up to 2 m 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.
