Alfalfa ( Medicago sativa ) is a plant species in the Fabaceae family. It is a perennial herb that can live for up to 20 years, reaching a height of 1 meter, with roots that extend as deep as 15 meters to reach groundwater. Its leaves are typically trifoliolate. The flower clusters consist of 5–20 blossoms, which are generally purple but can also be blue, yellow, or cream-colored. The seeds are small and yellowish. M. sativa is widely cultivated as fodder for dairy cows, horses, beef cattle, sheep, and goats. It can be grown in combination with various other crops. Raw alfalfa sprouts consist of 93% water, 2% carbohydrates, 1% fat, and 4% protein. In a 100-gram (3.5-ounce) serving, raw sprouts provide 23 calories and are high in vitamin K.
