The oil is obtained from the seed, and is considered superior to rape-seed oil, but is extracted with greater difficulty.
OKRA, OR GUMBO.
Ocra. Hibiscus esculentus.
Okra is a half-hardy annual, from Central America. Stem simple, sometimes branched at the top, and from two to six feet in height, according to the variety; the leaves are large, palmate, deep-green; the flowers are large, five-petaled, yellowish on the border, purple at the centre; the seed-pods are angular, or grooved, more or less sharply pointed, an inch or an inch and a half in diameter at the base, and from four to eight inches in length; the seeds are large, round-kidney-shaped, of a greenish-drab color, black or dark-brown at the eye, and retain their power of germination five years.
Soil, Sowing, and Cultivation.—Okra may be raised in any common garden soil, and is propagated by seeds sown in April or May. The Dwarf varieties may be grown in rows two feet apart, and a foot from each other in the rows; but the taller sorts require a space of at least three feet between the rows, and nearly two feet from plant to plant in the rows. Keep the soil about the plants loose and open; and, in the process of cultivation, earth up the stems slightly in the manner of earthing pease. The pods will be fit for use in August and September.
It requires a long, warm season; and is most productive when started in a hot-bed, and grown in a warm, sheltered situation.
Use.—The green pods are used while quite young, sliced in soups and similar dishes, to which they impart a thick, viscous, or gummy consistency. Thus served, they are esteemed not only healthful, but very nutritious.
The ripe seeds, roasted and ground, furnish a palatable substitute for coffee.
