About
White mustard (Sinapis alba), also called yellow mustard, is an annual plant of the cabbage family. It is sometimes also referred to as Brassica alba or B. hirta. It is native to the Mediterranean region, Europe and Tropical Asia, but is now widespread worldwide. Grown for its seeds, it is used to make the condiment mustard, as a fodder crop, or as a green manure.
Where it grows
Most common in Europe, North Africa, the Middle East and Central Asia, it can be found worldwide. It has been found as far north as Greenland, and naturalized throughout the British Isles.
Uses
The yellow flowers of the plant produce glabrous or sparsely bristled seed pods. Each fruit (silique) contains roughly a half dozen seeds. The plants are harvested for their seeds just prior to the seed pods becoming ripe and bursting open (dehiscing).
