Deadnettle

Lamium (deadnettle) is a genus of about 40-50 species of flowering plants 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 weeds of crop fields and are now widely naturalised across the temperate world.
The genus includes both annual and perennial species; they spread by both seeds and stems rooting as they grow along the ground.
The common name refers to their superficial resemblance to the unrelated stinging nettles, but unlike those, they do not have stinging hairs and so are harmless or apparently "dead".
