Lily of the Valley
(Convallaria), a genus of plants of the family Liliaceae. There is one species, C. majalis, with several varieties or subspecies, which are sometimes classified as independent species. The lily of the valley is an herbaceous perennial with a horizontal rootstock and two or three oblong-oval, pointed leaves with long petioles. The flower stalk, up to 20 cm tall, has a secund loose raceme of white, fragrant, bell-shaped, drooping flowers; the perianth has six lobes. The fruit is a spherical red berry. Lilies of the valley are widely found in the European USSR, the Caucasus, Eastern Siberia, and the Far East, as well as in Western Europe and North America. They grow profusely in light forests, on forest edges, and in shrub thickets.
The species C. majalis is used as a medicinal plant. Its above-ground parts contain cardiac glycosides (chiefly convallatoxin and convallarin), which intensify the contractile activity of the heart. An infusion of the plant is used, as well as the crystalline glycoside convallotoxin and corglykon, an extract containing all the glycosides of the lily of the valley. It is cultivated as an ornamental, chiefly for forcing, but also in gardens and parks. Cultivated forms of C. majalis are large and multiflowered. Some varieties have pinkish or double flowers, and some have mottled leaves.
