Coarse perennial herb with an extensively spreading, matted root system, forming clumps, 30-150 cm tall.

The various small species described as vicariads of this plant, as well as the numerous infraspecific taxa recorded from Turkey and elsewhere, need monographic treatment. Field studies are unattractive, but without such intimate contact, judgement on the critical segregates of this common nettle would be rash.
