A common name for chard. Chard (Beta vulgaris subsp. vulgaris, Cicla-Group and Flavescens-Group) is a leafy green vegetable often used in Mediterranean cooking. In the Flavescens-Group-cultivars, the leaf stalks are large and are often prepared separately from the leaf blade. The leaf blade can be green or reddish in color; the leaf stalks also vary in color, usually white, yellow, or red. Chard has highly nutritious leaves making it a popular addition to healthful diets (like other green leafy vegetables). Chard has been around for centuries, but because of its similarity to other beets and some other vegetables such as cardoon, the common names used by cooks over the centuries can be quite confusing.
