White Mustard, also known as Sinapis alba and previously as Brassica alba and Brassica hirta. This plant is part of the cabbage family and is grown mainly for its seeds and as a green manure. It is a cool-season, hardy annual that will suppress other weeds if grown in mass. White Mustard seeds are mixed with Black Mustard seed to make English mustard.

Special features of White Mustard

Crop rotation

When ploughed back into the ground, it improves the soil in orchards and vineyards by providing nitrogen to the earth (green manure).

Other uses of White Mustard



The same properties as with Brassica nigra, but less potent. Seldom used internally in the West, but popular in the East for treatment of coughs, arthritis, fungus and as a poultice.


Seeds produce oil, spice and flour, which is used in herbal medicine. Young leaves and sprouted seeds used in salads. Used for animal feed, but NOT after it has flowered and developed fruit.

Green manure

Used as a green manure as it is fast growing to cover your soil.
