Lettuce is without doubt the world's most popular salad plant. Lettuce is a fairly hardy, cool-weather vegetable that thrives when the average daily temperature is between 60 and 70°F and is most often grown as a leaf vegetable. In Western countries, it is typically eaten cold and raw. In some places, including China, lettuce is typically eaten cooked and the use of the stem is as important as use of the leaf.
