Cabbage is a very common vegetable native to England and northwestern France but now grown in many parts of Europe, Asia, and the American continents. There are three kinds of cabbage, and all have the common characteristic of leaves grown very close together, forming a hard round head. The three types are white, Savoy, and red. While the white and red cabbage have prominent veins in their leaves, the Savoy has wrinkled and blistered leaves.
Cabbage seeds are quite small. Farmers normally sow the seed in rows that are about 36 inches apart. After young plants have sprouted, the rows are thinned to allow a space of 18 to 24 inches apart between plants. Cabbage is a biennial. Farmers nomarlly grow it one year, store it during the winter, and replant it in the spring to produce seeds. By controlling the temperature to which the plant is subjected in this way, famers can produce either heads or seeds.
