Three Dead-nettles of Spring: How to Tell Them Apart

Early spring in North Wales brings a flush of low-growing colour to verges, gardens, field edges and disturbed ground. Among the most familiar are the dead-nettles — a group of plants that look like stinging nettles but don’t sting at all.

At first glance, several species look very similar. Here we take a closer look at three that are all flowering now: Red Dead-nettle (Lamium purpureum), Cut-leaved Dead-nettle (Lamium hybridum), and Spotted Dead-nettle (Lamium maculatum). With a bit of practice, they are easy to tell apart.

Getting to Know Dead-nettles

All three species belong to the mint family and share some key features. They have square stems, opposite leaves, and soft, often hairy foliage. Their flowers are small but distinctive, with a hooded upper lip and a lower lip that acts as a landing platform for insects.

They are also valuable early nectar sources, especially for bees emerging in late winter and early spring.

Red Dead-nettle (Lamium purpureum)

This is by far the most common species and is likely the one most people notice.

It is a low-growing annual that thrives on disturbed ground, including field margins, roadside verges, gardens and waste places. The leaves are soft, rounded to heart-shaped, and often develop a reddish or purplish tint towards the top of the plant.

The flowers are pink to reddish-purple and cluster tightly near the top. A useful feature is that all the leaves have stalks, even those just below the flowers.

In North Wales

Red Dead-nettle is abundant across North Wales, from coastal areas to inland farmland and towns. It is often one of the first wildflowers to appear in the year.

Cut-leaved Dead-nettle (Lamium hybridum)

This species is easily overlooked because it often grows alongside Red Dead-nettle and looks similar at first glance.

The key difference lies in the leaves. The upper leaves are deeply cut and sharply toothed, giving them a more jagged and irregular appearance. In contrast, Red Dead-nettle has softer, more rounded leaves.

The flowers are usually smaller and fewer, and the plant can appear slightly less robust overall.

In North Wales

Cut-leaved Dead-nettle is less frequently recorded but is probably under-recorded due to confusion with Red Dead-nettle. It occurs in similar habitats, so it is always worth checking patches carefully.

Spotted Dead-nettle (Lamium maculatum)

This species is quite different once you know what to look for.

It is a perennial and often forms spreading patches rather than individual plants. The leaves are typically marked with a pale or silvery stripe along the centre, although this can vary.

The flowers are larger than those of the other two species and can be pink, purple or white. The plant often has a more sprawling habit and is commonly found in shaded conditions.

In North Wales

Spotted Dead-nettle is often associated with gardens and can escape into the wild. You are most likely to find it along hedgerows, woodland edges and near habitation.

How to Tell Them Apart

A quick way to separate them in the field:

• Deeply cut, jagged leaves → Cut-leaved Dead-nettle

• Rounded leaves with reddish upper growth → Red Dead-nettle

• Leaves with pale or silvery markings and a spreading habit → Spotted Dead-nettle

Why They Matter

Dead-nettles are often dismissed as weeds, but they play an important role in early spring. When few other plants are in flower, they provide a valuable source of nectar and pollen for insects.

They are also a good reminder that even common plants are worth a closer look. What appears to be a single species can reveal surprising variety with just a little attention.

A Final Thought

Next time you are out on a spring walk in North Wales, take a closer look at the ground beneath your feet.

That patch of dead-nettles may be more than it first appears.
