Stinging nettle in British Columbia is represented by two subspecies: 1) Urtica dioica spp. dioica (which is an introduced taxon in North America) and Urtica dioica ssp gracilis (which is the native stinging nettle). Urtica dioica ssp gracilis is found throughout most of North America, while subspecies dioica is found mainly in the eastern and western states and provinces (AK, AL, CA, CT, DC, DE, FL, GA, IL, IN, MA, MD, ME, MI, NC, NH, NJ, NY, OH, OK, OR, PA, RI, SC, TN, VA, VT, WA, WV and BC, NB, NF, NS, ON, PE, QC), but is absent from the mid-west and prairie provinces (USDA 2010). In BC, the native subspecies is widespread, while the distribution of the introduced subspecies is not fully known. There are confirmed observations from the Greater Vancouver area (Vancouver, Burnaby, New Westminster, Surrey, Coquitlam), it is to be expected on Vancouver Island, and it may be present in the BC interior (Frank Lomer pers. com. 2010). It is confirmed on Valdes Island (see photo #24310). Further work is needed to clarify its extent of occurrence in the province. The two subspecies are separated by flower morphology, and the presence of stinging hairs on either one or both leaf surfaces. See the identification key below for more details.
