THE LEEK.
Allium porrum.
The Leek is a hardy biennial, and produces an oblong, tunicated bulb; from the base of which, rootlets are put forth in great numbers. The plant, when full grown, much resembles what are commonly known as "Scallions;" the lower, blanched portion being the part eaten. This varies in length from four to eight inches, and in diameter from less than an inch to more than three inches. The leaves are long, narrow, smooth, and pointed; and spread in opposite directions, somewhat in the form of a fan. The flower-stem proceeds from the centre of this collection of leaves, and is about four feet in height. The flowers are white, with a stripe of red, and are produced in terminal, globular groups, or umbels; the seeds are black, irregular, but somewhat triangular in form, and, with the exception of their smaller size, are similar to those of the onion. About twelve thousand seeds are contained in an ounce; and they retain their vitality two years.
Soil, Sowing, and Cultivation.—The Leek is very hardy, and easily cultivated. It succeeds best in a light but well-enriched soil. When fine leeks are desired, it can hardly be made too rich. It should also be thoroughly spaded over, and well pulverized to the depth of at least twelve inches. The seed should be sown in April, at the bottom of drills made six or eight inches deep, and eighteen inches asunder. Sow the seeds thinly, cover half an inch deep, and thin the young plants to nine inches distant in the drills. As the plants increase in size, draw the earth gradually into the drills, and around the stems of the leeks, until the drills are filled. By this process, the bulbs are blanched, and rendered tender and mild flavored. The seeds are sometimes sown broadcast, and in July transplanted to trenches, and subsequently cultivated, as before directed. The plants are also sometimes set on the surface, and afterwards earthed up to the height of six or eight inches in the process of cultivation. In October, the leeks will be suitable for use; and, until the closing-up of the ground, may be drawn from time to time as required for the table. For winter use, they should be preserved in earth or sand.
Early leeks may be obtained by sowing the seeds in a hot-bed in February or March, and transplanting to the open ground in June or July.
Seed.—To obtain seed, some of the finest plants of the growth of the previous year should be set out in April, fifteen inches apart, and the stems sunk to the depth of three or four inches. "The seed ripens in autumn, and its maturity is known by the heads changing to a brown color. It is best preserved in the heads; and these should be cut off with a portion of the stalk a foot in length, tied in bunches, and hung in a dry, airy situation. In this manner, the seed will retain its vegetative powers for two or three years: after that time, it is not to be depended on."—Thomp.
Use.—"The whole plant, except the roots, is used in soups and stews. The white stems, which are blanched by being planted deep for the purpose, are boiled, served with toasted bread and white sauce, and eaten like asparagus." It has the flavor, and possesses the general properties, of the onion.
