description_en: Genus of 30 species of annuals and evergreen biennials, perennials, or rarely subshrubs, occurring on rocky slopes, and waste and disturbed ground from the Mediterranean to temperate Asia. Most are erect, branching, tap-rooted plants, with oblong-ovate to rounded, entire or pinnately lobed, hairless, more or less glaucous leaves. They bear terminal racemes of cross-shaped, yellow or white flowers with 4 clawed petals, followed by long, narrow, beaked fruits. Brassica species have been developed to produce many edible vegetables, including cabbage, sprouts, cauliflower, and broccoli (all variants of B. oleracea), and turnip, Chinese cabbage, and oilseed rape. Most are grown in the vegetable garden, although some ornamental cabbages - with variegated pink, white, or green foliage - are used in a border or for a bedding display.

hardiness_en: Fully hardy, but flower-heads of edible vegetables may be damaged in severe winters.
