Rue, Sour Herb of Grace
Uses.—Because of the exceedingly strong smell of the leaves, rue is disagreeable to most Americans, and could not become popular as a seasoning. Yet it is used to a small extent by people who like bitter flavors, not only in culinary preparations, but in beverages. The whole plant is used in distilling a colorless oil which is used in making aromatic vinegars and other toilet preparations. A pound of oil may be secured from 150 to 200 pounds of the plant.
Sage (Salvia officinalis, Linn.), a perennial member of the Labiatæ, found naturally on dry, calcareous hills in southern Europe, and northern Africa. In ancient times, it was one of the most highly esteemed of all plants because of its reputed health-insuring properties. An old adage reads, "How can a man die in whose garden sage is growing?" Its very names betoken the high regard in which it was held; salvia is derived from salvus, to be safe, or salveo, to be in good health or to heal; (hence also salvation!) and officinalis stamps its authority or indicates its recognized official standing. The name sage, meaning wisdom, appears to have had a different origin, but as the plant was reputed to strengthen the memory, there seems to be ground for believing that those who ate the plant would be wise.
Description.—The almost woody stems rise usually 15 to 18 inches high, though in Holt's Mammoth double these sizes is not uncommon. The leaves are oblong, pale green, finely toothed, lance-shaped, wrinkled and rough. The usually bluish-lilac, sometimes pink or white flowers, borne in the axils of the upper leaves in whorls of three or four, form loose terminal spikes or clusters. Over 7,000 of the small globular, almost black seeds, which retain their vitality about three years, are required to weigh an ounce, and nearly 20 ounces to the quart.
Cultivation.—Sage does best upon mellow well-drained soil of moderate fertility. For cultivation on a large scale the soil should be plowed deeply and allowed to remain in the rough furrows during the winter, to be broken up as much as possible by the frost. In the spring it should be fined for the crop. Sage is easily propagated by division, layers and cuttings, but these ways are practiced on an extensive scale only with the Holt's Mammoth variety, which produces no seed. For other varieties seed is most popular. This is sown in drills at the rate of two seeds to the inch and covered about ¼ inch deep. At this rate and in rows 15 inches apart about 8 pounds of seed will be needed to the acre.

Usually market gardeners prefer to grow sage as a second crop. They therefore raise the plants in nursery beds. The seed is sown in very early spring, not thicker than already mentioned, but in rows closer together, 6 to 9 inches usually. From the start the seedlings are kept clean cultivated and encouraged to grow stocky. By late May or early June the first sowings of summer vegetables will have been marketed and the ground ready for the sage. The ground is then put in good condition and the sage seedlings transplanted 6 or 8 inches apart usually. Clean cultivation is maintained until the sage has possession.
When the plants meet, usually during late August, the alternate ones are cut, bunched and sold. At this time one plant should make a good bunch. When the rows meet in mid-September, the alternate rows are marketed, a plant then making about two bunches. By the middle of October the final cutting may be started, when the remaining plants should be large enough to make about three bunches each. This last cutting may continue well into November without serious loss of lower leaves. If the plants are not thinned, but are allowed to crowd, the lower leaves will turn yellow and drop off, thus entailing loss.
