Red dead-nettle or something else? Telling lookalikes apart
Several plants look similar at a glance. The differences are small but clear when you know where to look, especially the leaf stalks and the flower colour.
Red dead-nettle vs henbit dead-nettle
Henbit dead-nettle (Lamium amplexicaule) is the closest lookalike. Both are low annuals with purple flowers, and both appear in gardens and fields. Henbit is usually 10 to 25 cm tall, with soft, finely hairy stems and rounded to kidney-shaped leaves with lobed edges. The key difference is the leaves on the flowering stems: red dead-nettle has leaves with short stalks, while henbit's upper leaves are stalkless and wrap around the stem. Henbit also has a longer, more slender flower tube and the flowers often look as if they are stacked in rings around the stem. It blooms very early in spring and can self-pollinate when few insects are active.
Red dead-nettle vs white dead-nettle
White dead-nettle (Lamium album) is a perennial, not an annual, and grows up to about 70 cm tall. Its leaves are triangular, softly hairy and nettle-like, 3 to 8 cm long with serrated edges, but they do not sting. The white flowers grow in whorls on the upper stem, each 1.5 to 2.5 cm long, much bigger than red dead-nettle's. Bumblebees are especially attracted to them because the flowers give early nectar and pollen, hence the nickname "bee nettle". The two are easy to separate by flower colour and size.
Red dead-nettle vs stinging nettle
Stinging nettle (Urtica dioica) is not a close relative. It has stinging hairs, greenish flowers that hang in tassels and a taller, tougher growth habit. Red dead-nettle is soft, small and has no stings. If a plant stings you, it is not a dead-nettle. Do not rely on touch alone to identify a plant; look at the flowers and stem as well.

Other plants that can cause confusion
Other members of the mint family can look similar when small, including the spotted and cut-leaved dead-nettles, and yellow archangel. Ground-ivy and some hemp-nettles are also similar at a glance. See related species for a closer look at the dead-nettle family.
Why it matters for foraging
Most dead-nettles are not harmful, but you should never eat a plant you have not identified with certainty. A wrong guess might not just be unpleasant: it could be dangerous, especially in the case of lookalikes from other families. Read the foraging cautions first.
A quick method
- Check the stem: square means mint family.
- Check for a sting (carefully, using a gloved hand if unsure).
- Look at the flower colour and size.
- Look at whether the upper leaves are stalked or clasping.
- Check the height and whether it is annual or perennial.

Frequently asked questions
What is the difference between red dead-nettle and henbit?
Red dead-nettle's leaves on the flowering stems have short stalks, while henbit's upper leaves are stalkless and clasp the stem.
Is white dead-nettle the same as red dead-nettle?
No. White dead-nettle (Lamium album) is a taller perennial with white flowers and triangular nettle-like leaves, while red dead-nettle is a small annual with pinkish-purple flowers.
Is red dead-nettle related to stinging nettle?
No. It looks similar but is unrelated and does not sting.
