Lamium album, commonly called white dead-nettle, [2] [3] is a flowering plant in the family Lamiaceae. It is native throughout Europe and Asia , growing in a variety of habitats from open grassland to woodland, generally on moist, fertile soils .
The common name "dead-nettle" has been derived from the German Taubnessel ("deaf nettle", or "nettle without a kernel"), [11] and refers to the resemblance of Lamium album [12] to the very distantly related stinging nettles, but unlike those, they do not have stinging hairs and so are harmless or apparently "dead".
Urtica dioica, often known as common nettle, burn nettle, stinging nettle (although not all plants of this species sting) or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, [2] it is now found worldwide.

Urticating hairs of a stinging nettle. The most common form of urticating hairs in plants are typified by nettles, which possess sharp-pointed hollow bristles seated on a gland that secretes an acrid fluid. The points of these bristles usually break off in the wound, and the acrid fluid is pressed into it.
Lamium purpureum grows with square stems to 5–20 centimetres (2–8 in), [4] rarely 40 cm, in height. [5] The leaves have fine hairs, are green at the bottom and shade to purplish at the top; they are 2–4 centimetres (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long and broad, with a 1–2 cm petiole (leaf stalk), and wavy to serrated margins.
