Origin

This species has a very widespread (i.e. cosmopolitan) distribution, and its exact origin is obscure. However, it is thought to be native to parts of Europe and/or the Mediterranean region.

Naturalised Distribution

Widely naturalised, particularly in southern and eastern Australia. It is common in south-eastern Queensland, eastern and southern New South Wales, the ACT, Victoria, Tasmania, south-eastern South Australia and south-western Western Australia. Less common or occasionally naturalised in some parts of Northern Territory and in other parts of Queensland, New South Wales, South Australia and Western Australia. Also naturalised on Lord Howe Island and Norfolk Island.

Widely naturalised overseas, including in large parts of North America (i.e. Canada and the USA).

Notes

While small nettle (Urtica urens) is mainly a weed of agricultural areas and habitation, it is sometimes also regarded as environmental weed in Victoria, Queensland and Western Australia.
