Description

Laportea canadensis grows from tuberous roots to a height of 30 to 150 centimeters, and can be rhizomatous, growing into small clumps. Plants have both stinging and non stinging hairs on the foliage and the stems. It has whitish green flowers, produced from spring to early fall. Unlike its cousin the common nettle, Laportea canadensis has alternate leaves. The bulk of its foliage also grows notably high on the stem.

Sting

When the stinging nettles come in contact with the skin, the unlucky individual is dealt a painful burning stinging sensation, sometimes with barbs left in the skin. The skin can turn red and blister, and blisters can last for several days.
