It is from the seeds of the black and white mustards that the well-known condiment is made. For this purpose the plants are extensively cultivated in Europe, and are sown as forage for cattle, when they are cut down and fed to them before the seeds are ripe. With us they flourish along the roadsides and are rather troublesome weeds in some parts of the country.
Sinapis alba, or white mustard, has single seeds; the long hairy pods are beaked.
