Stinging nettle (Urticaria urens)
Description: A tall green herbaceous perennial weed with stems that sting when touched, small round green leaves and tiny white flowers. The stinging sensation is caused by fine hairs along the stem and is very painful. Stinging nettles are a sign of good soils.
Control: Use a selective herbicide for flatweeds, spot treat with glyphosate or hand-weed before flowering. When hand-weeding, remove entire taproot (main root). To control flowers and seedlings without removing plants, simply mow.
