Red leaf lettuce is a widely consumed leafy vegetable valued for its attractive color, tender texture, and mild flavor. It is an important commodity in fresh produce markets, commonly used in both retail and food service sectors. Red leaf lettuce is typically marketed as whole heads or loose leaves and is popular in salads and fresh preparations.
