This is what I found about stinging nettles and wood nettles:

Laportea canadensis, commonly called Canada nettle or wood-nettle, is an annual or perennial herbaceous plant of the nettle family Urticaceae, native to eastern and central North America. It is found growing in open woods with moist rich soils and along streams and in drainages.

Urtica is a genus of flowering plants in the family Urticaceae. Many species have stinging hairs and may be called nettles or stinging nettles, although the latter name applies particularly to Urtica dioica.

Urtica dioica, often known as common nettle, or stinging nettle is a herbaceous perennial floweriing plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America.

Urtica urens, commonly known as annual nettle, dwarf nettle, small nettle, dog nettle, or burning nettle, is a herbaceous annual flowering plant species in the nettle family Urticaceae. It is native to Eurasia and it can be found in North America and New Zealand as an introduced species. It is reputed to sting more strongly than common (stinging) nettle.
