Valerianella locusta is a small annual plant that is eaten as a leaf vegetable. It has a characteristic nutty flavor, dark green color, and soft texture, and is popularly served as salad greens. Common names include corn salad, common cornsalad, lamb's lettuce, mâche (/mɑːʃ/), fetticus, feldsalat, nut lettuce, field salad, and rapunzel. In restaurants that feature French cooking, it may be called doucette or raiponce, as an alternative to mâche, by which it is best known. In German-speaking Switzerland it is known as Nüsslisalat or Nüssler, terms that have been borrowed by the area's many English-speakers.
