Wild B. oleracea is a tall biennial plant, forming a stout rosette of large leaves in the first year, the leaves being fleshier and thicker than those of other species of Brassica, adaptations to store water and nutrients in its difficult growing environment. In its second year, the stored nutrients are used to produce a flower spike 1to 2 metres (3-7ft) tall bearing numerous yellow flowers.In its uncultivated form, it is known as wild cabbage. It is native to coastal southern and western Europe. Its high tolerance of salt and lime and its intolerance of competition from other plants typically restrict its natural occurrence to limestone sea cliffs, like the chalk cliffs on both sides of the English Channel, and the windswept coast on the western side of the Isle of Wight.Brassica oleracea is the species of plant that includes many common foods as cultivars, including cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, savoy, kohlrabi and kai-lan.
B. oleracea has become established as an important human food crop plant, used because of its large food reserves, which are stored over the winter in its leaves. It is rich in essential nutrients including vitamin C. A diet rich in cruciferous vegetables (e.g., cabbage, broccoli, cauliflower) is linked to a reduced risk of several human cancers.
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 (): a curly-leaved, a smooth-leaved, and a wild-type. 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. It has been bred into a wide range of cultivars, including cabbage, broccoli, cauliflower, brussels sprouts, collards, and kale, some of which are hardly recognisable as being members of the same genus, let alone species. The historical genus of Crucifera, meaning "cross-bearing," may be the only unifying feature beyond taste.
According to the Triangle of U theory, B. oleracea is very closely related to five other species of the genus Brassica.
The cultivars of B. oleracea are grouped by developmental form into seven major cultivar groups, of which the Acephala ("non-heading") group remains most like the natural Wild Cabbage in appearance:
In places such as the Channel Islands and Canary Islands where the frost is minimal and plants are thus freed from seasonality, some cultivars, known as Jersey cabbages, can grow up to three meters tall. These "tree cabbages" yield fresh leaves throughout the year, are perennial, and do not need to be destroyed at harvest as with a normal cabbage. Their woody stalks are sometimes dried and made into walking sticks.
With the advent of agriculture and the domestication of wild crop plants, the peoples of the Mediterranean began cultivating wild cabbage. Through artificial selection for various phenotype traits the emergence of variations of the plant with drastic differences in looks took only a few thousand years. Preference for leaves, terminal bud, lateral bud, stem and inflorescence evolved the wild cabbage into the many forms we know today.
