Brown Mustard. Red Mustard. Sinapis nigra.
Black Mustard is a hardy, annual plant, introduced from Europe. In some localities, it grows naturally in great abundance; and is regarded as a troublesome weed, though its seeds furnish the common table mustard. Its stem is four or five feet in height, round, smooth, and branching; the leaves are lobed and toothed on the margin,—the radical or lower ones rough, those of the upper portion of the stalk smooth; the flowers are numerous, rather large, bright-yellow; the pods are erect, somewhat four-sided, and are set closely against the sides of the stalk; the seeds are small, round, brownish-black, and retain their germinative powers many years; nearly eighteen thousand are contained in an ounce.
Propagation and Cultivation.—It is raised from seeds, about four quarts of which will be required for sowing an acre. It is sometimes grown in the vegetable garden, but is generally cultivated in fields for its seeds, which, as before remarked, furnish the common table mustard. The sowing is usually made from the middle of April to the middle of May. After making the surface of the ground fine and smooth, sow broadcast, or thinly in shallow drills fourteen or fifteen inches apart; cultivate during the season in the usual manner; and, in August, the crop will be ready for harvesting. Cut the stalks at the ground before the pods shed their seeds; and spread in a dry, light, and airy situation, till they are sufficiently dried for threshing.
When grown for salad in the vegetable garden, it should be sown, and cut for use, as directed for White Mustard.
"If the seed is covered to the depth of three inches or more, it will lie dormant, and retain its powers of vegetation for ages: from which circumstance, together with the liability of the seed to become shaken out in the harvesting of the crop, such lands as are once employed for the growing of Mustard cannot be fairly cleaned of it for a considerable length of time, and only by judicious fallowing or fallow-cropping, with repeated hoeing and weeding."—Law.
Use.—Besides the use of the flour of the seeds as a condiment, the seed-leaves are used as salad, in the manner of those of the White species; and the young plants, cut to the ground, are used as spring greens, either boiled alone, or mixed with Spinach.
Chinese Or Pekin Mustard. Vil.
Sinapis Pekinensis.
A hardy annual, introduced from China. Stem four feet high, with remarkably large leaves; the flowers, which are produced in loose, terminal spikes, are yellow and showy; the seeds are small, and retain their vitality five years.
Cultivation.—The seeds are sown in April or May, in shallow drills ten or twelve inches apart. If cultivated for its seeds, the drills should be eighteen inches or two feet apart, and the plants thinned to six or eight inches in the drills.
