Vegetable
Brassica rapa
S tier
Brassica rapa is the broad species that includes bok choy, napa cabbage, turnips, and many Asian greens—bok choy being the non-heading form with white or green petioles and spoon-shaped leaves. Mild mustard notes stay gentler than true mustard greens. Growth is fast; overmaturity brings hollow stems and stronger bite. Recipes for bok choy, pak choi, and many “Chinese greens” sit under B. rapa chinensis-group plants. Stir-fry, steam, or braise; separate stems and leaves for even cooking. Species identity links these greens to their turnip cousins.
