Corn salad (Valerianella locusta (Linnaeus) or Valerianella olitoria (Moench) - the synonym Valeriana is obsolete but appears frequently in older texts)   is a small dicot annual plant of the family Valerianaceae. It is also called Lewiston cornsalad, lamb's lettuce, fetticus, field salad, mâche, feldsalat, nut lettuce and rapunzel. 
Corn salad grows in a low rosette with spatulate leaves up to 15.2 cm long. It is a hardy plant that grows to zone 5, and in mild climates it is grown as a winter green. In warm conditions it tends to bolt to seed.
Corn salad grows wild in parts of Europe, northern Africa and western Asia. In Europe and Asia it is a common weed in cultivated land and waste spaces. In North America it has escaped cultivation and become naturalized on both the eastern and western seaboards.
Corn salad was originally foraged by European peasants until the royal gardener of King Louis XIV, de la Quintinie, introduced it to the world. It has also been used as food in Britain for many centuries and appears in John Gerard's Herbal of 1597 but only became commercially available there in the 1980s.  It was grown commercially in London from the late 18th/early 19th century and appeared on markets as a winter vegetable. See 'Vegetables and their Culivation', Sanders, T. W. 1917. The common name corn salad refers to the fact that it often grows as a weed in wheat fields. 
Like other formerly foraged greens, corn salad has many nutrients, including three times as much vitamin C as lettuce, beta-carotene, B6, B9, vitamin E, and omega-3 fatty acids. It is best if gathered before flowers appear.
