Cabbage is a 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 cabbages 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 normally grow it one year, store it during the winter, and replant it in the spring to produce seed. By controlling the temperatureto which the plant is subjected in this way, fammers can produce either heads or seeds.
