Cabbages range in colour from pale green to purple-red, and have dense, compact heads with smooth, tightly packed, waxy leaves. Savoy cabbage has leaves that are brighter green and crinkled, while ruby red to purple coloured leaves distinguish red cabbage. Chinese cabbage, such as Pe-Tsai, grows in an elongated form with tightly wrapped, pale-green leaves. However, the Napa variety is more barrel-shaped with yellowish-green leaves. They are all flavourful.
