Mustard - Brassica nigra
Family: Brassicaceae
Flowers from May to June
Description
This weed is also known as Sinapis nigra and commonly as shortpod mustard. Like other mustards, this plant has 4 yellow petals and 6 stammen. Differentiating it from other mustards is tricky. The upper leaves are linear-oblong, entire or sinuate, glabrous and dentate with all leaves petiolate; flowers in enlongate racemes, regular petals yellow, 7–9 mm long, stamens 6, fruit a silique, long slender beaked pod.
Similar species include Wild Mustard, and Field Mustard
Interesting facts
This plant is harvested for use in our everyday mustards. Often it is combined with Brassica alba, to make some of the more common mustards. Another use of this plant is to use the oil (allyl isothiocyanate) as a dog and cat repellant.
Black Mustard is probably native to the Mediterranean area, although there is still some debate, and is now widespread across most of the world.
