Valerianella locusta is a small dicot annual plant of the family Valerianaceae. It is an edible salad green with a characteristic nutty flavor, dark green color, and soft texture. Common names include corn salad (or cornsalad), lamb's lettuce, mâche, fetticus, feldsalat, nut lettuce, field salad and rapunzel. In restaurants that feature French cooking, this salad green may be called doucette or raiponce, as an alternative to mâche, by which it is best known.
