Valerianella (diminutive of Valeriana). Valerianaceae. Annual dichotomously branched herbs, chiefly spring plants, sometimes planted in wild-garden or rock-garden; one is a salad plant.
Leaves, lower, in a radical rosette, entire; cauline entire, dentate or rarely incise-pinnatifid: cymes sometimes corymbosely paniculate fastigiate, sometimes densely globose at the ends of the branches: fls. whitish, pale bluish, or rose; corolla-tube short or rarely elongate, limb 5-cleft, spreading; stamens 3: fr. 3-celled, 2 of which are empty.—About 58 species, Eu., N. Afr., W. Asia, and N. Amer., mostly in the Medit. region.
Corn salad is both a salad plant and a pot-herb, chiefly the former. The name "corn salad" is probably derived from the fact that the plant grows spontaneously in the grain-fields of Europe, large quantities of it being gathered in early spring. It is rather tasteless compared with lettuce, and is little known in America. Abroad it is prized as a fall and winter salad. It is a cool-season crop, grown like lettuce and matures in six to eight weeks. Plants should stand about 6 inches apart in the row. An ounce of seed should give 2,000 to 3,000 plants.
Sow seed in early spring to late summer, where the plants are to grow.
