A genus of about 50 species of annuals and perennials, occurring in habitats from dry scrub to moist woodland. The common name dead nettle refers to their resemblance to "stinging nettles", but the two are unrelated; and unlike stinging nettles, Lamium does not have stinging hairs. Although semi-evergreen in temperate climates, the plants are inclined to look a little untidy in winter; but grow with a vengeance again in spring. It is best to cut this plant back after the first bloom to promote compact growth. They are grown as ground covers in gardens.
