Stinging Nettle.

[Keith]

Stinging nettles can also be boiled or steamed as a green veg to go with other dishes. To me it tastes like Spinach. This plant grows widely in the UK & in Australia.

you can take the sting out of nettles by wilting them over a fire.

 

[Ystranc]

Extremely rich in vitamins and iron, if you strip the leaves off to cook them the fibrous stems make good cordage.
If I don't need cordage I usually just pick the leaves from the tip.

Also makes good plant fertiliser.
