Napa cabbage is a densely packed, large and elongated head, averaging 25-50 centimeters in length and 15-20 centimeters in width, with an oval to oblong shape. The bright white stems are thick, lightly grooved, and smooth, tightly clustered at the base forming basal rosettes. Attached to the fibrous stems are crinkled, delicate, and curved leaves that range in color from pale green to yellow and are covered in white veins that extend across the surface. Napa cabbage is crisp and aqueous with a subtly sweet, mild flavor.
