'''''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.
The genus includes both [[annual plant|annual]] and [[perennial plant|perennial]] species; they spread by both [[seed]]s and stems rooting as they grow along the ground.
The common name refers to their superficial resemblance to the unrelated [[nettle|stinging nettle]]s, but unlike those, they do not have stinging hairs and so are harmless or apparently "dead".
;Selected species
*''[[Lamium album]]'' ([[White Deadnettle]])
*''[[Lamium amplexicaule]]'' ([[Henbit Deadnettle]])
*''[[Lamium bifidum]]''
*''[[Lamium barbatum]]''
*''[[Lamium corsicum]]''
*''[[Lamium flexuosum]]''
*''[[Lamium garganicum]]''
*''[[Lamium glaberrimum]]''
*''[[Lamium hybridum]]'' ([[Cut-leaf Deadnettle]])
*''[[Lamium maculatum]]'' ([[Spotted Deadnettle]])
*''[[Lamium moluccellifolium]]'' ([[Northern Deadnettle]])
*''[[Lamium moschatum]]''
*''[[Lamium orvala]]''
*''[[Lamium purpureum]]'' ([[Red Deadnettle]])
Several closely related genera were formerly included in ''Lamium'' by some [[botanist]]s, including ''[[Lamiastrum]]'' (Yellow Archangel), ''[[Galeopsis]]'' (hemp-nettles) and ''[[Leonurus]]'' (motherworts).
''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.
