The Barberry is an ornamental shrub, on account of its graceful yellow blossoms and its bright scarlet berries. The fruit is often prescribed by village doctors for the jaundice, but from its sourness it is seldom eaten uncooked. It makes excellent jelly, and is much used in the manufacture of sugar-plums. The roots and bark yield a yellow dye. Cattle and sheep eat the leaves, and the flowers are attractive to insects.

The barberry formerly grew wild, in great quantities, in our English hedgerows, but it has been extirpated from a belief that it injures the growth of corn. It is said that the leaves are frequently infested by a tiny fungus, similar to one which attacks wheat: this is easily dispersed by the wind, and propagatad amongst the corn, causing it much injury.

The barberry seems to be widely distributed: it is found in America, and in most European countries, especially on the shores of the Danube.
