Small Nettle - Urtica urens

Short to medium plant with weakly stinging hairs, the leaves more coarsely toothed than U. dioica and the lower leaves shortly stalked, not long stalked. Male and female flowers on the same plant, many female and few male, in ascending spikes.

Urtica dioica

Annual.  Usually smaller and more compact than Common Nettle (although this is very variable in size) with more jaggedly toothed leaves; terminal leaf-tooth about as long as adjacent laterals (terminal leaf-tooth is longer in common nettle)

Cultivated, waste and disturbed ground, gardens.

June to October.

Annual.

Common throughout Britain, especially in the east.

Fairly frequent in Leicestershire and Rutland. In the 1979 Flora survey of Leicestershire it was found in 267 of the 617 tetrads.
