Brassica rapa L. is a plant consisting of various widely cultivated subspecies including the turnip (a root vegetable); the mizuna, napa cabbage, and cime di rapa (leaf vegetables); and turnip rape (Brassica rapa subsp. oleifera, an oilseed which has many common names, including turnip rape, canola, field mustard, bird rape, keblock, and colza). The oilseed is sometimes confused with rapeseed oil, which however comes from a different Brassica species.
