Chard [Beta vulgaris subsp. cicla], is a leafy green vegetable often used in Mediterranean cooking. While the leaves are always green, chard stalks vary in color. Chard is being cultivated to have highly nutritious leaves at the expense of the root. Chard is considered one of the healthiest vegetables available and a valuable addition to a healthy diet. Chard has been around for centuries, but because of its similarity to beets is difficult to determine the exact evolution of the different varieties of chard.
