The stinging nettle has to be one of the most unpopular plants, with none being intentionally cultivated for aesthetic reasons, except perhaps by the masochist.
The only reason this particular editor can imagine planting them in a domestic setting would be to be as a barrier to humans and many animals.
Nettles have however been a source of food, fibre and medicine for centuries. When soaked in water or cooked, the stinging chemicals are removed, leaving a source of green nutrition that is packed with vitamins and important minerals.
It is often used as an alternative to spinach, especially in Greece where it is used in Spanakopita if spinach is not available.
Nettles are also used extensively in herbal teas or brewed into beer and the fibres, though coarser than cotton, make a very durable woven fabric.
As a medicine nettles have been used over millennia to treat disorders of the kidneys and urinary tract, gastrointestinal tract, skin, cardiovascular system, hemorrhage, influenza, rheumatism and gout while also promoting lactation in new mothers.
Its a horrible plant - but clearly has many uses, including adding to composts to increase nitrogen content, or steeping in water and applying as a fertiliser.
