Swiss chard is a cold tolerant biennial that is closely related to the beet. It is native to southern Europe and much older than the beet. It is believed to have developed from a form of wild beet thousands of years ago. White, yellow and dark green forms of chard have been known since ancient times. Aristotle mentions a red-stalked chard around 350 BC.
Swiss chard has been grown both as a vegetable crop and also as an ornamental. It was introduced into the United States by the colonists who considered it another form of beet grown for its greens.
