'''Nettle''' is the common name for between 30-45 species of [[flowering plant]]s of the genus ''Urtica'' in the family [[Urticaceae]], with a [[cosmopolitan distribution|cosmopolitan]] though mainly temperate distribution. They are mostly [[herbaceous]] [[perennial plant]]s, but some are [[annual plant|annual]] and a few are [[shrub]]by. The most prominent member of the [[genus]] is the [[stinging nettle]] ''Urtica dioica'',{{citation needed|date=February 2010}} native to [[Europe]], [[Africa]], [[Asia]], and [[North America]]. The genus also contains a number of other species with similar properties, listed below. {{Inc| 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. {{SCH}} }} ==Cultivation== ===Propagation=== ===Pests and diseases=== ==Species== Species in the genus ''Urtica'', and their primary natural ranges, include: *''Urtica angustifolia'' Fisch. ex Hornem. 1819.
