Nettle is the common name for between 30-45 species of flowering plants of the genus Urtica in the family Urticaceae, with a cosmopolitan though mainly temperate distribution. They are mostly herbaceous perennial plants, but some are annual and a few are shrubby.

The most prominent member of the genus is the stinging nettle Urtica dioica,^{[citation needed]} native to Europe, Africa, Asia, and North America. The genus also contains a number of other species with similar properties, listed below.

Urtica (classical name, alluding to the burning hairs). Urticaceae. Nettle. About 30 annual and perennial erect simple or branching slender herbs, widely distributed, little if at all planted because of the stinging hairs and sts. and lvs.: fls. small, greenish and inconspicuous, racemose, spicate or clustered in the axils, monoecious or dioecious, sometimes hermaphrodite; sterile fls. with 4 sepals and 4 stamens; fertile fls. with 2 pairs of sepals and a single erect ovary: lvs. simple, opposite, strongly nerved, dentate or crenate or incised. Several species of nettle are native in N. Amer. and a few are intro. weeds. The plants have very little ornamental value. CH The above text is from the Standard Cyclopedia of Horticulture.
