Boxer Brassica oleracea
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.
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 seacliffs, like the chalk cliffs on both sides of the English Channel, and the windswept coast on the western side of the Isle of Wight.
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 1 to 2 metres (3–7 ft) tall bearing numerous yellow flowers.
