Commonly called stinging nettle (Urtica urens) due to its leaves with stinging hairs on its leaves, which when brushed against cause a painful rash on human skin. Nettle is found throughout New Zealand especially in cropping areas and in pasture where it is not grazed by stock. Nettle can be a challenging weed in fodder beet crops as it is only susceptible to post-emergence herbicides as a seedling (3-4 leaf stage).
