What is an alternate name for lamb's lettuce?

Lamb's lettuce is commonly known as corn salad. This name originates from the fact that it often grows as a weed among corn crops. The scientific name for lamb's lettuce is Valerianella locusta, and it is characterized by its tender, rosette-shaped leaves and a mild, slightly nutty flavor. This leafy green is often used in salads and garnishes, particularly in European cuisine.

The other options represent distinct greens: arugula is known for its peppery flavor, spinach is a leafy vegetable with a wide range of culinary uses, and romaine is a variety of lettuce often used in Caesar salads. Each of these has its own unique characteristics and does not refer to lamb's lettuce.
