Brassica rapa L. is a plant consisting of various widely cultivated subspecies including the turnip (a root vegetable); the mizuna, napa cabbage, bok choy, and cime di rapa (leaf vegetables); and (Brassica rapa subsp. oleifera, an oilseed which has many common names, including field mustard, bird rape, keblock, and colza).
The oil made from the seed is sometimes also called canola, which is one reason why it is sometimes confused with rapeseed oil, but this comes from a different Brassica species (Brassica napus). The oilseeds known as canola are sometimes particular varieties of Brassica rapa (termed Polish Canola) but usually the related species Brassica napus (rapeseed) and Brassica juncea (mustard greens).
