'''''Brassica oleracea''''', or '''Wild Cabbage''', is a species of ''[[Brassica]]'' native to coastal southern and western [[Europe]], where its tolerance of [[sodium chloride|salt]] and [[calcium carbonate|lime]] and its intolerance of competition from other plants typically restrict its natural occurrence to [[limestone]] [[sea]] [[cliff]]s, like the chalk cliffs on both sides of the [[English Channel]].
 +
 +
Wild ''B. olearacea'' is a tall [[biennial plant]], forming a stout rosette of large [[leaf|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 {{convert|1|to(-)|2|m|ft|0}} tall bearing numerous yellow flowers.
 +
 +
It has been bred into a wide range of [[cultivar]]s, 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 [[cruciferous vegetables|crucifera]], meaning four-petalled flower, may be the only uniting feature beyond taste. It has become established as an important human food [[agriculture|crop]] plant. According to the [[Triangle of U]] theory, ''B. oleracea'' is very closely related to five other species of the genus ''[[Brassica]]''.<ref name=Dixon2007>{{Citation

Brassica oleracea, Linn. Cabbage, Cauliflower, Brussels Sprouts, Kale. Fig. 627. Lvs. smooth from the first, and the root not tuberous: fls. large and long (¾-1 in. length, at least often), light- colored, slender- pedicelled, in long and open racemes: pods large, long-beaked. If the name Brassica oleracea is held for a generalized group without a type form, then the wild plant may be designated as var. syl- vestris, Linn. In the present treatment, however, the wild form is regarded as the type and is therefore not given a varietal name. Brassica oleracea grows wild on the sea-cliffs of W. and S. Eu. Fig. 628, from nature, shows the common form as it grows on the chalk cliffs of the English Channel. It is a perennial plan t of short duration, or perhaps sometimes a biennial, with a very tough and woody root, a diffuse habit, and large thick deep- lobed Ivs. in various shades of green and reddish, and more or less glaucous. The Ivs. of this plant were probably eaten by the barbarous or half-civilized peoples; and, when history begins, the plant had been transferred to cult, grounds and had begun to produce dense rosettes or heads of Ivs. It appears to have been in general use before the Aryan migrations to the westward. There were several distinct types or races of the cabbage in cult, in Pliny's time. From the one original stock have apparently sprung all the forms of cabbages, cauliflowers, brussels sprouts and kales. For this family or group of plants the English language has no generic name. The French include them all under the term Chou, and the Germans treat them under Kohl. These various tribes may be classified as follows:

'''''Brassica oleracea''''' or '''Wild Cabbage''', is a species of ''[[Brassica]]'' native to coastal southern and western [[Europe]], where its tolerance of [[sodium chloride|salt]] and [[calcium carbonate|lime]] but intolerance of competition from other plants typically restricts its natural occurrence to [[limestone]] [[sea]] [[cliff]]s.

===Propagation===
   −
Wild ''B. olearacea'' is a tall [[biennial plant]], forming a stout rosette of large [[leaf|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 1–2 m tall bearing numerous yellow flowers.

===Pests and diseases===

Although ''B. oleracea'' is believed to have been cultivated for several thousand years, its history as a domesticated plant is not clear before [[ancient Greece|Greek]] and [[ancient Rome|Roman]] times, when is known to be a well-established garden vegetable. [[Theophrastus]] mentions three kinds of this species: a curly-leaved, a smooth-leaved, and a wild-type.<ref>Daniel Zohary and Maria Hopf, ''Domestication of plants in the Old World'', third edition (Oxford: Oxford University Press, 2000), p. 199.</ref> It has been bred into a wide range of [[cultivar]]s, including [[cabbage]], [[broccoli]], [[cauliflower]], and more, some of which are hardly recognisable as being members of the same species. It is one of the most important human food [[agriculture|crop]] plants. According to the [[Triangle of U]] theory, ''B. oleracea'' is very closely related to five other species of the genus ''[[Brassica]]''.
     −
The plant is 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]].
