The flowers are bilabiate with yellow crowns. Lamium grows in deciduous forests, in shrubbery, and by the edges of forests in Europe and Asia (in the Caucasus and Iran).

(dead nettle), a genus of plants of the family Labiatae. The plants are annual, biennial, or perennial herbs with toothed entire leaves. The white, pink, or purple flowers are in false whorls and are situated in the axils of the upper leaves. The fruit consists of four three-angled nutlets. There are 40 to 50 species, distributed in Europe, nontropical Asia, and North Africa. About 15 species occur in the USSR. The white dead nettle (L.album) yields a substantial amount of nectar (seeWHITE DEAD NETTLE). Another important nectar-bearer is L. purpureum, which grows in deciduous forests and on mountain slopes. L.amplexicaule is a weed. Several species, including L. maculatum, are cultivated as ornamentals.
