This purple-flowered Clover is extensively raised in the Western and Southern States where hundreds of thousands of tons are annually harvested for fodder. It makes the best grade of hay, and has been cultivated for at least two thousand years. The smooth, slender, upright or ascending stalk is much branched, and grows a foot or more high. The three-parted leaves are short stemmed, and the leaflets much resemble those of the Stone Clover in a general way. They are a little broader, however, and the blunt apex is more abrupt and ragged toothed. The middle one is offset from the others in a little kinked stem. The joints are sheathed after the manner of the latter species, though slightly modified. The rather pretty flower head is composed of numerous violet, purple or bluish florets, arranged in several short, dense clusters on slender stems. The seed pod is curiously twisted into two or three spires. Alfalfa grows wild during the summer, in fields and waste places most everywhere from New England and Ontario, westward and southward.
