SAINFOIN
Sainfoin (Onobrychis sativa) is a perennial, leguminous, clover-like forage plant of the bean family. The word Sainfoin is equivalent to the French words for sound or wholesome hay. It is also frequently called Esparcette or Asperset, more especially in Germany. It is further known in England by the name Cock's Head, French Grass and Medick Vetchling. In some parts of France and Switzerland the name has been and probably is yet applied to lucerne (Medicago sativa).
In its habit of growth it is more woody in the rootstock than clover and more branched. It also grows to a greater average height. The stems, which are covered with fine hairs, bear numerous leaves long and pinnate. The blossoms are numerous and of an attractive, pinkish color, brightening into a crimson tint. The seed pods are flattened from side to side and wrinkled, and are also sickle-shaped. They bear but one seed. The roots are strong and more or less branched.
Sainfoin, as already intimated, is perennial in its habit of growth. When a field is once well set with the plants, it should continue to produce crops for a decade, but will eventually be crowded out with weeds or other grasses. It grows very early in the season, quite as early, if not earlier, than alfalfa, and continues to grow until autumn.
The feeding value of sainfoin is much the same as that of alfalfa. It is much esteemed where it can be grown for the production of pasture, of soiling food, and also hay, valuable for enriching the land, through the medium of the roots, and also when the tops are plowed under as green manure.
Sainfoin is native throughout the whole of Central Europe and over much of Siberia. Although native to the southern counties of England, it does not appear to have been cultivated there before the year 1651, at which time it is said to have been introduced from Flanders. From what has been said with reference to the distribution of sainfoin in Europe and Asia, it will be apparent that it is a hardy plant, which has highest adaptation for climates temperate and mild to moderately cool. Its hardihood has been shown by its surviving the winters in the latitude of the St. Lawrence River, but the abundant snow covering then provided should not be lost sight of.

Its adaptation to the United States does not appear to have been proved yet, except in limited areas. In some of the Montana valleys good crops have been grown with much success in many of those western valleys, and even on the bench lands at the base of foothills. Nor would there seem to be any good reasons for supposing that good crops could not be grown in various parts of the United States where the soil is suitable.
