SEA-CABBAGE, SEA-BEACH KALE, or SEA-COLEWORT; a genus of the filifera order, belonging to the tetradynamia class of plants. There are three species, all of them herbaceous eculents with perennial roots, producing annually large leaves resembling those of cabbage spreading on the ground, with strong flower-stalks and yellowish flowers. Only one of the species is a native of Britain: it grows wild on the shores of many of the maritime counties of England, but is cultivated in many gardens as a choice eculent; and the young robust shoots of its leaves and flower-stalks, as they issue forth from the earth after the manner of asparagus shoots, are then in the greatest perfection for use. At this period they appear white as if blanched, and when boiled eat exceeding sweet and tender. Its principal season for use is in April and May. This plant may also be employed in the pleasure-ground as a flowering perennial, for the stalks divide into fine branchy heads of flowers. It is propagated by seeds sown in any common light earth in autumn or spring, where the plants are to remain, which, when two years old, will produce shoots fit for use, will multiply exceedingly by the roots, and continue for many years.
