'''''Lamium''''' ('''deadnettle''') is a genus of about 40-50 species of [[flowering plant]]s in the family [[Lamiaceae]], of which family it is the type genus. They are all [[herbaceous]] plants native to [[Europe]], [[Asia]], and north [[Africa]], but several have become very successful [[weed]]s of [[agriculture|crop]] fields and are now widely [[naturalisation (biology)|naturalised]] across the temperate world.

''Lamium'' species are used as food plants by the [[larva]]e of some [[Lepidoptera]] species including [[Angle Shades]], [[Setaceous Hebrew Character]] and the ''[[Coleophora]]'' case-bearers ''C. ballotella'', ''C. lineolea'' and ''C. ochripennella''.

== Cultivation ==

Lamiums are frost hardy and grow well in most soils.  Flower colour determines planting season and light requirement: white- and purple-coloured flowered species are planted in spring and prefer full sun.  The yellow-flowered ones are planted in fall (autumn) and prefer shade.  They often have [[invasive species|invasive]] habits and need plenty of room.  Propagate from seed or by division in early spring.

Lamium (Greek for throat, referring to the shape of the corolla). Labiatae. Dead Nettle. Annual and perennial herbs of the Old World, of which several run wild in this country as weeds and others are cultivated as hardy border plants. Botanically, Lamium is distinguished by a 2-lipped corolla, of which the tube is somewhat longer than the calyx, the upper lip ascending and concave, and the lower one 3-lobed: stamens 4, in 2 pairs, ascending under the upper lip: fls. in axillary or terminal whorls, often rather showy: lvs. opposite, mostly crenatedentate and petiolate: calyx awl-toothed.—Low herbs, of some 40 species in Eu., N. Afr. and Asia. Lamiums are diffuse mostly pubescent or hairy herbs, commonly decumbent at the base and often almost trailing. They are of the easiest culture in any open soil. Useful for rockwork. The cultivated kinds are perennial, and are commonly propagated by division.CH
