Kale has large stringy leaves, very curly, with a well-marked flavor. Their color varies from pale green to dark green, sometimes to blue-tinted green. Those leaves are not well rounded, a characteristic expressed by the Latin word which describes this variety of cabbage « acephala » and which means « without head ». Those leaves surmount a fine whitish and very fibrous stem, it can measure from 30 to 40 cm. Kale is so decorative that ornamental varieties were developed.
