Lettuce is an annual plant in the daisy family. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce was first cultivated by the ancient Egyptians who turned it from a weed, whose seeds were used to produce oil, into a food plant grown for its succulent leaves. The Romans gave it the name “lactuca”, from which the English “lettuce” is ultimately derived.
