Napa cabbage is sometimes called Chinese cabbage or celery cabbage. Napa cabbage doesn't look like head cabbages. It has long light green leaves that flower off of thick, white stalks. It looks a bit like a cross between romaine lettuce and pale Swiss chard. It has a lovely mild flavor with a peppery kick that is delicious in salads or stir-frys. You can also turn it into spicy kimchi.
