The Hop
Humulus lupulus.
The Hop is considered a native of this continent, and is found wild in all parts of the United States. The root is perennial, but the stems are annual. The latter are from ten to twenty-five feet in length, angular, rough, and twine from right to left. The leaves are placed opposite each other on the stem, on long, winding footstalks: the smaller ones are heart-shaped; the larger ones three or five lobed, veiny, and rough. The barren and fertile flowers are produced on separate plants: the former being very numerous and paniculated; the latter in the form of an ament, or collection of small scales, which are more or less covered with a fine, yellow powder called "lupulin."
While several distinct sorts of the fertile or hop-bearing plant have been long in cultivation, only one variety of the male or barren plant is known.
Soil and Location.—Though it may be cultivated with success in a variety of soils, the Hop prefers a rich, deep loam, which should be thoroughly ploughed, and, if necessary, enriched with well-digested compost. In general, it may be said that "good corn-land is good hop-land." Hops, however, are reputed to be of better quality when raised on comparatively thin soils.
Propagation and Culture.—It is propagated by a division of the roots early in spring. When extensively cultivated, the plants are set in hills, five to seven feet apart, and three or four cuttings or slips allowed to a hill; but in garden culture, to procure the young shoots, the plants are set in rows about three feet apart, and one foot from plant to plant in the rows.
Use.—The plant is principally cultivated for its flowers, which are largely employed in the manufacture of malt liquors. The young shoots are cut in spring, when they are five or six inches in height, and eaten as salad, or used as asparagus, which they somewhat resemble in taste.
