Urtica dioica
by KennetRose
If you go walking at all in England, and you should, you will certainly encounter the stinging nettle. It's not as dangerous as the poison ivy of the American woods, but brush against it and it will give you a rash of unpleasant stings. The trouble is, it's so very, very common and it just loves growing where people have been. Lost settlements have been located by the nettles growing thickly where the latrines were (it's the nitrogen), and they have a habit of growing in dense clumps right across your path, just where you have to walk..Grab hold of the leaves boldly and they don't sting. Be timid about it and they do. Hence the phrase "to grasp the nettle". Country people use this as a trick to play on townies, or so I'm told. .Make sure your legs and arms are well covered when walking in the countryside!
