Cabbage belongs to the Cruciferae(mustard)family and is of the genus Brassica, species oleracea, variety capitata. The plant is cultivated for its large leafy head. Flowers are formed on a terminal raceme (growth axis) and have four sepals (outer leaves) in the form of a cross. Cabbage roots are mostly in the upper 12 inches of the soil.
Most cabbage is green, but there are also varieties withredor purple foliage. The heads are more or less compact, depending on the variety, and range in shape from roundish to oval to flattened spheres. The heads consist of numerous thick, overlapping smooth leaves. In some varieties 1eaves are much crinkled. These are ca11ed savoy types.
The following advice on characteristics to look for in buying cabbage is taken from USDA's pamphlet "How to Buy Fresh Vegetables":"Look for: Firm or hard heads of cabbage that are heavy for their size. Outer leaves should be a good green or red color (depending on type), reasonably fresh, and free from serious blemishes. The outer leaves (called"wrapper" leaves) fit loosely on the head and are usually discarded, but too many loose wrapper leaves on a head cause extra waste.
"Some early-crop cabbage may be soft or only fairly firm--but is suitable for immediate use if the leaves are fresh and crisp. Cabbage out of storage is usually trimmed of all outer leaves and lacks green color, but is satisfactory if not wilted or discolored.
"Avoid: New cabbage with wilted or decayed outer leaves or with leaves turning decidedly yellow. Worm-eaten outer leaves often indicate that the worm injury penetrates into the head. Storage cabbage with outer leaves badly discolored, dried, or decayed probably is over-aged. Separation of the stems of leaves from the central stem at the base of the head also indicates over-age."
