Red Dead-nettle

Lamium purpureum

Red Dead-nettle is traditionally known as the ‘bumblebee flower’ in some British counties as bumblebees love it! Other names include ‘sweet archangel’ and ‘bad man’s posies’. Red Dead-nettle is related to the stinging nettle but has no sting – hence the ‘dead’ in ‘dead-nettle’.

How to spot it

Red Dead-nettle has whorls of pink-purple flowers clustered amongst leaves towards the top of the plant. The aromatic leaves are hairy, heart-shaped and have toothed edges. Some leaves near the top of the plant take on a purple tint. This plant can be mistaken for henbit dead-nettle which has similar flowers. They can be differentiated because Red Dead-nettle leaves have short petioles (leaf stalks).

Where to spot it

Found throughout the UK, Red Dead-nettle likes arable and waste land and can also be found in gardens, hedgerows and on roadsides.

Best time to spot it

Red dead-nettle has a long flowering season that can begin in February and last until November.

Things you might not know

  • The generic name is from the Greek lamia meaning ‘devouring monster’. This refers to the helmet shape (galeate) of the flower which has the appearance of open jaws.
  • The vernacular name ‘Archangel’ may refer to their virtue of being non-stinging.
  • It is likely that this plant was introduced to Britain with early agriculture and evidence for it has been found in Bronze Age deposits.
  • The whole plant is astringent, diaphoretic, diuretic, purgative and styptic. In terms of traditional medicinal uses, dried leaves have been used as a poultice to stem hemorrhaging whilst fresh bruised leaves have been applied to external wounds and cuts. The leaves are also made into a tea and drunk to promote perspiration and discharge from the kidneys in treating chills.
