Children delight to eat the leaves of this very common Sorrel, which is found from one end of the United States to the other. They often call it Sour Grass, because its agreeable sour taste has a flavour, they fancy, not unlike that of the Red Sorrel, Rumex acetosa. These leaves are useful as a remedy for certain affections of the skin, when eaten in a fresh state. The smooth, leafy stalk is branched and spreading, and grows about six inches high. The thin Clover-like leaf is composed of three short, broad heart-shaped leaflets with their points united at the tip of their long, slender stem. They are pale green in colour, and droop and fold together at night. They are also very sensitive, and close if roughly handled. The fragrant, bright golden yellow flowers open in the sunlight, and close at sundown. They are arranged in small groups at the head of the stalk, and are set on long stems that grow from the axils of the leaf stems. The five, small spreading petals are very thin, and are supported by a five-parted green calyx. The Lady's Sorrel blossoms from April to October, in woods and fields, or along roadsides and about gardens everywhere. Naturalized from Europe.
