Although it is believed to have been cultivated for several thousand years, its history as a domesticated plant is not clear before Greek and Roman times, when it was a well-established garden vegetable. Theophrastus mentions three kinds of rhaphanos (ῤάφανος):[3] a curly-leaved, a smooth-leaved, and a wild-type.[4] He reports the antipathy of the cabbage and the grape vine, for the ancients believed cabbages grown near grapes would impart their flavour to the wine.[5] It has been bred into a wide range of cultivars, including cabbage, broccoli, cauliflower, and more, some of which are hardly recognisable as being members of the same genus, let alone species. The historical genus of Crucifera, meaning four-petalled flower, may be the only unifying feature beyond taste.
