Lettuce (Lactuca Sativa) is a green annual plant of Asteraceae family. It is one of the oldest and most popular leafy vegetables originated from the Mediterranean region. It received its name from the Latin word for milk “lac” for its milky sap. There are five main classes of lettuce and over a hundred of various types, including typical “Iceberg”, “Great Lakes”, “Boston”, “Buttercrunch” or “New York”, red “Rosy”, small “Mini Green” or “Tom Thumb”, etc., which are different in their color and shape. Some lettuce plants have a rosette of broad soft leaves or long sword-shaped leaves, some have cabbage heads with crispy leaves, some have loose heads with puffy inner leaves and some have edible stems.
