A leaf vegetable, Lactuca sativa, cultivated by the ancient Egyptians as early as 2680 BC, though the earliest domesticated form was grown chiefly for its oil-rich seeds rather than its leaves, a use that shifted over centuries of selective breeding toward the leafy varieties grown today. Lettuce spread from Egypt to Greece and Rome in antiquity and later across Europe, developing into distinct types such as crisphead (iceberg), butterhead, romaine and loose-leaf lettuce. It is now grown as a major vegetable crop worldwide, with China and the United States among the largest producers, typically as a fast-maturing, cool-season annual.
