Hi Diamond Lil, Nettles do work! then you can selectively eat the nettles too, very good for you.

They're also very good for osteo arthritis. To do with the production of histamine

lets not forget the humble stinging nettle, Urtica dioica. It will purify land from pollutants (ready for other crops in a season or two), they can act as a nice deterrent, medically they're very effective for a range of issues, including topically as a very effective pain killer and to induce blood flow to the surface, very easily grow! and is highly nutritious! natures multi-vitamin! it was eaten as a spring tonic by our ancestors due to the lack of nutrients over winter! easy to make nettle wine / beer too! win-win all round

great idea on scattering seeds in certain places though! blackberries and strawberries too will grow very well and add some extra vitamins and flavours to your SHTF diet
