Valerianella locusta is a small annual plant that is eaten as a leaf vegetable. It has a characteristic nutty flavour, dark green colour, and soft texture, and is popularly served as salad greens. Common names include lamb's lettuce, corn salad, common cornsalad, mâche (/mɑːʃ/), fetticus, feldsalat, nut lettuce, field salad. 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. In some areas of Germany it is known as rapunzel, and is the origin of the long-haired maiden's name in the eponymous fairy tale.
