Lettuce
History and Facts:
The earliest cultivated lettuces were the loose-leaf types. The loose heading and the firm heading forms occurred much later. Modern forms of lettuce are believed to be derived from a wild form that grows as a weed in most areas where lettuce is found.
Nutritional Value:
Lettuce is very low in calories, and provides desirable roughage for improved digestion. Lettuce, especially the greener types, provides a useful amount of vitamin A, vitamin C, iron and potassium.
Storage:
Lettuce should be stored at 32 degrees fahrenheit with a relative humidity of 98 to 100 percent. Under these conditions, lettuce should store well for two to three weeks.

November through May
