Valerianella locusta is a small dicot annual plant of the family Caprifoliaceae that is an edible leaf vegetable with a characteristic nutty flavor, dark green color, and soft texture, popularly served as salad greens. Common names include corn salad, common cornsalad, lamb's lettuce, mâche, 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.
