Complete guide to dead nettles

How to identify dead nettles

Red dead-nettle

Red dead-nettle (Lamium purpureum) is one of the most common wild dead-nettles found across Britain and Ireland. Also known as purple dead-nettle, this annual has pinky-purple flowers growing in whorls around the stem. It grows to a height of around 40cm.

White dead-nettle

White dead-nettle (Lamium album) is another common wild plant which reaches around 60cm. This herbaceous perennial grows in hedges and on roadsides and rough ground. As its name suggests, it has white flowers.

Spotted dead-nettle

Spotted dead-nettle (Lamium maculatum) is a perennial garden escape which has become common in the wild across much of England. It grows to 60cm and the leaves are usually covered in silver blotches. Flowers are pinky-purple, though they can vary considerably in colour, and the lower petal can have darker purple blotches.

Yellow archangel

Yellow archangel (Lamiastrum galeobdolon) is no longer in the same genus as other dead-nettles, but it's sometimes known as yellow dead-nettle. This perennial grows to around 60cm and can be found in woodland and hedgerows. Lamiastrum galeobdolon subsp. montanum is the most common native subspecies. It has green leaves and hairy stems.

Lamiastrum galeobdolon subsp. argentatum is a garden escape. It can be identified by the silver-white blotches on its leaves which persist all year. It’s an invasive non-native species listed on Schedule 9 of the UK Wildlife & Countryside Act. It’s an offence to plant it in the wild or allow it to spread from your garden into the wild.

Value to wildlife

Dead-nettles are good for wildlife. Their long flowering period provides nectar for long-tongued pollinating insects including bumblebees and solitary bees. Their leaves are also a food source for a number of beetles, aphids, flies and caterpillars of several moth species, such as the garden tiger and large twin-spot carpet.

How to grow dead nettle

Dead nettles are suitable for wildlife gardens and wildflower meadows.

Where to grow dead nettle

Dead-nettles are ideal to use as ground cover in wildlife areas and to sow or plant in wildflower meadows.

How to plant dead nettle

Sow dead-nettle seed in well-prepared soil where you want it to flower. In wildflower meadows, plant out plug plants or sow seeds in areas of bare soil.

How to care for dead nettle

Dead-nettles need very little care once established.

Foraging for dead nettles

Dead-nettles are not poisonous to humans and they don't sting, but they can be confused with stinging nettles and some poisonous plants, such as foxgloves, especially before the flowers appear. Young red and white dead-nettle leaves can be used sparingly in salads and steamed as a vegetable. As with all foraged plants, check that you don’t have a condition that means you shouldn’t eat them and seek advice from a doctor if you are pregnant or breastfeeding. If you're foraging, make sure you use good field guides to identify plants or go on a guided walk with an expert.

Don’t pick unless you're 100 per cent certain your identification is correct. Only collect where plants are abundant (generally the advice is only to harvest from one in 20 plants) and leave plenty behind for wildlife. Seek permission before foraging and bear in mind that uprooting any plant is illegal without the landowner’s permission.

Pests and diseases

Dead-nettles are generally free of diseases. If you find caterpillars or other invertebrates on your dead-nettles, you know your plants are supporting healthy garden ecosystems.
