Galeopsis tetrahit - Common Hempnettle

The square-sectioned hairy stalks and straggly appearance of this member of the mint family are a help in its identification. The flowers themselves are usually pinkish-purple but quite commonly, as in the sample below, they are almost white. Yellow-flowered specimens also occur in some parts of the UK.

Common hemp-nettle

The flowers first appear in July and continue blooming until September. Hedgerows are its more normal habitat, but we have also found common hemp-nettle on the gravelly shallows of spate rivers and it is occasionally seen in open woodland too.
