If seed be sown as soon as ripe, plants may be secured which mature earlier than the main crop. Thus six or eight weeks may be saved in the growing season, and by continuing such selection a quick-maturing strain may be secured with little effort. This would also obviate the trouble of keeping seed from one year to the next, for the strain would be practically a winter annual.
Uses.—Occasionally the leaves and young shoots are eaten either cooked or as an ingredient in salads. The roots, too, have been esteemed in some countries, even more highly than the parsnip, which, however, largely because of its size, has supplanted it for this purpose. But the seeds are the important part. They find popular use in bread, cheese, liquors, salads, sauces, soups, candy, and especially in seed cakes, cookies and comfits. The colorless or pale yellow essential oil distilled with water from the seeds, which contain between 5% and 7½% of it, has the characteristic flavor and odor of the fruit. It is extensively employed in the manufacture of toilet articles, such as perfumery, and especially soaps.
Catnip, or cat mint (Nepeta cataria, Linn.), a perennial herb of the natural order Labiatæ. The popular name is in allusion to the attraction the plant has for cats. They not only eat it, but rub themselves upon it purring with delight. The generic name is derived from the Etrurian city Neptic, in the neighborhood of which various species of the genus formerly became prominent.
Like several of its relatives catnip is a well-known weed. It has become naturalized in America, and is most frequently observed in dry, waste places, especially in the East, though it is also often found in gardens and around dwellings throughout the United States and Canada.
Description.—Its erect, square, branching stems, from 18 to 36 inches tall, bear notched oval or heartshaped leaves, whitish below, and during late summer terminal clusters of white flowers in small heads, far apart below, but crowded close above. The fruits are small, brown, ovoid, smooth and with three clearly defined angles. An ounce contains about 3,400 seeds. Viability lasts for five years.
Catnip, Pussy's Delight
Cultivation. Catnip will grow with the most ordinary attention on any fairly dry soil. The seed need only be sown in autumn or spring where the plants are to remain or in a nursery bed for subsequent transplanting. If to be kept in a garden bed they should stand 18 to 24 inches apart each way. Nothing is needful except to keep down weeds in order to have them succeed for several years on the same spot.
Uses.—The most important use of the plant is as a bee forage; for this purpose waste places are often planted to catnip. As a condiment the leaves were formerly in popular use, especially in the form of sauces; but milder flavors are now more highly esteemed. Still, the French use catnip to a considerable extent. Like many of its relatives, catnip was a popular medicinal remedy for many fleshly ills; now it is practically relegated to domestic medicine. Even in this it is a moribund remedy for infant flatulence, and is clung to only by unlettered nurses of a passing generation.
Chervil (Scandix Cerefolium, Linn.), a southern Europe annual, with stems about 18 inches tall and bearing few divided leaves composed of oval, much-cut leaflets. The small white flowers, borne in umbels, are followed by long, pointed, black seeds with a conspicuous furrow from end to end. These seeds, which retain their germinability about three years, but are rather difficult to keep, may be sown where the plants are to stay, at any season, about eight weeks before a crop is desired; cultivation is like that of parsley. During summer and in warm climates, cool, shady situations should be chosen, otherwise any situation and soil are suitable. The leaves, which are highly aromatic, are used, especially in France and England, for seasoning and for mixed salads. Chervil is rarely used alone, but is the chief ingredient in what the French call fines herbes, a mixture which finds its way into a host of culinary concoctions. The best variety is the Curled, which, though it has the same flavor as the plain, is a prettier garnish.
