Henbit vs Purple Dead Nettle: How to Tell These Spring Weeds Apart

Henbit vs Purple Dead Nettle: How to Tell These Spring Weeds Apart

The Great Spring Confusion: Henbit and Purple Dead Nettle

If you've ever spotted small purple flowers carpeting your lawn or garden in early spring, you've probably encountered either henbit or purple dead nettle—or quite possibly both! These two plants are remarkably similar and often grow side by side, blooming at the same time and thriving in the same conditions. Even experienced foragers sometimes need a second look to tell them apart. But once you know the key differences, identifying them becomes easy.

Before we dive into the details, let's clear up the biggest source of confusion: despite having "nettle" in its name, purple dead nettle is NOT related to stinging nettle (Urtica dioica). It doesn't sting, it's in a completely different plant family, and it doesn't offer the same nutritive benefits as true nettle. The "nettle" in its name simply refers to the superficial resemblance of its leaves to nettle leaves—nothing more. So if you're looking for the mineral-rich, nutritive powerhouse we call stinging nettle, purple dead nettle won't deliver the same results. That said, it's still a useful and interesting plant in its own right!

Meet the Plants: Henbit and Purple Dead Nettle

Henbit (Lamium amplexicaule) and Purple Dead Nettle (Lamium purpureum) are both members of the mint family (Lamiaceae), which explains their square stems and opposite leaves. Originally native to Europe and Asia, they've naturalized throughout North America and are often considered weeds—though many herbalists and foragers recognize them as valuable edible and medicinal spring greens.

Both plants are cool-season annuals or biennials, meaning they thrive in the cooler temperatures of early spring and fall. They're often among the very first plants to bloom in late winter or early spring, providing crucial early nectar for bees and other pollinators when little else is flowering. For this reason alone, many gardeners have learned to appreciate these common "weeds" rather than fight them.

Why "Dead" Nettle? Clearing Up the Name

The name can be confusing, so let's address it directly: Purple dead nettle is called "dead nettle" because it resembles stinging nettle but doesn't sting—hence, it's "dead" or harmless. That's the entire explanation.

Here's what you need to know:

  • Stinging nettle (Urtica dioica) is in the Urticaceae family and is covered with stinging hairs that inject irritating compounds into your skin
  • Purple dead nettle (Lamium purpureum) is in the mint family (Lamiaceae) and has no stinging hairs whatsoever—it's completely safe to touch
  • Henbit (Lamium amplexicaule) is also in the mint family and also doesn't sting

The confusion arises because dead nettle leaves have a somewhat similar shape to nettle leaves—both have toothed edges and grow in opposite pairs. But that's where the similarity ends. Dead nettle and henbit are gentle, non-stinging plants that are actually quite pleasant to handle and eat.

How to Tell Henbit and Purple Dead Nettle Apart

Ready to learn the key differences? Here's what to look for:

Leaf Shape and Attachment (The Most Reliable Identifier)

This is the easiest and most reliable way to distinguish these two plants:

Henbit: The lower leaves have stems (petioles), but the upper leaves are stalkless and clasp directly around the stem. These upper leaves are rounded, scalloped, and fan-shaped, creating a distinctive layered appearance. They're bright green and look like small ruffles stacked up the stem.

Purple Dead Nettle: ALL the leaves have stems—none of them clasp the stem directly. The leaves are more triangular or heart-shaped with pointed tips and more deeply toothed edges. The upper leaves often have a purple or burgundy tint, especially in full sun or cooler weather.

Quick identification tip: If the upper leaves wrap around the stem with no leaf stalk, it's henbit. If all the leaves have little stems, it's purple dead nettle.

Leaf Color

Henbit: Leaves are typically bright green throughout the plant, though they may develop a slight purple tinge in very cold weather.

Purple Dead Nettle: The upper leaves are often distinctly purple, burgundy, or deep green with purple tones, especially at the top of the plant. This purple coloration is where it gets its common name. In shadier conditions, the leaves may be greener, but there's usually still some purple tinting visible.

Flowers

Both plants have tubular, two-lipped flowers typical of the mint family, with subtle differences:

Henbit: The flowers are pink to purple and emerge from the leaf axils in whorls. The flowers have a longer, more slender tube and the upper lip is quite hairy. The color tends to be a lighter, pinker purple.

Purple Dead Nettle: The flowers are also pink to purple but tend to be a deeper, richer purple. They're clustered at the top of the plant among the purple-tinged leaves. The flower tube is shorter and stouter than henbit's.

Overall Growth Habit

Henbit: Tends to grow more upright and can reach 12-16 inches tall. The plant has a more open, airy appearance with the distinctive clasping leaves creating a layered look up the stem.

Purple Dead Nettle: Usually grows lower and more compact (6-12 inches), often forming dense mats. The purple-topped foliage creates a distinctive colorful carpet effect, especially in large patches.

Stems

Both have square stems (a mint family characteristic), but:

Henbit: Stems are green and relatively smooth.

Purple Dead Nettle: Stems are often tinged with purple and may be slightly hairy.

Where They Grow

Both henbit and purple dead nettle thrive in similar habitats, which is why you often find them growing together:

  • Lawns and gardens (especially disturbed soil)
  • Fields and pastures
  • Roadsides and waste areas
  • Along fence lines and edges
  • Anywhere with moist, fertile soil and partial to full sun

They're both opportunistic plants that take advantage of bare soil and cooler temperatures. You'll typically see them blooming from late winter through mid-spring (February through May in most areas), and sometimes again in fall.

Are They Edible and Medicinal?

Yes! Both henbit and purple dead nettle are edible and have been used in traditional herbal medicine, though they're much milder and less well-known than their namesake, stinging nettle.

Henbit

Edible uses: The young leaves, stems, and flowers are all edible. Henbit has a mild, slightly sweet flavor with a hint of mint. It can be eaten raw in salads, added to smoothies, cooked like spinach, or used in soups and stir-fries. The flowers make a pretty edible garnish.

Traditional uses: Henbit has been used traditionally as a gentle diaphoretic (promotes sweating), mild astringent, and for supporting respiratory health. It's also been used topically for minor wounds and skin irritations.

Purple Dead Nettle

Edible uses: Like henbit, the leaves, stems, and flowers are edible. Purple dead nettle has a slightly earthier, more mineral-like flavor than henbit, with a hint of bitterness. It's excellent in salads, pesto, soups, or sautéed as a cooked green. The purple leaves add beautiful color to dishes.

Traditional uses: Purple dead nettle has been used as an anti-inflammatory, astringent, and for supporting kidney and urinary health. It's also been used topically for wounds, cuts, and skin conditions. Some herbalists use it to support women's health.

Important Note

While both plants are nutritious and useful, they are NOT substitutes for stinging nettle (Urtica dioica). Stinging nettle is far more nutrient-dense, particularly in minerals like iron, calcium, and magnesium, and has a much longer history of use as a powerful nutritive tonic. If you're looking for the deep mineral support and nourishing properties of nettle, you want actual stinging nettle, not dead nettle or henbit.

Harvesting and Using Henbit and Purple Dead Nettle

If you'd like to try these spring greens, here's how to harvest and use them:

When to harvest: Gather them in early spring when the plants are young and tender, before they get too tough or go to seed. The best time is in the morning after the dew has dried.

What to harvest: Snip the top 3-4 inches of the plant, including leaves, stems, and flowers. The younger, upper growth is the most tender and flavorful.

Where to harvest: Only harvest from areas you know haven't been sprayed with pesticides or herbicides. Avoid roadsides, dog parks, and areas with heavy foot traffic or pollution.

How to use:

  • Raw: Add young leaves and flowers to salads, smoothies, or use as a garnish
  • Cooked: Sauté like spinach, add to soups, stir-fries, omelets, or quiches
  • Pesto: Blend with garlic, olive oil, nuts, and parmesan for a spring pesto
  • Tea: Steep fresh or dried leaves in hot water for a mild, pleasant tea
  • Infused oil: Use fresh or dried herb to make an infused oil for topical use

Storage: Use fresh within a few days, or dry the leaves and flowers for later use. Spread them on screens in a warm, dry, well-ventilated area out of direct sunlight until crispy-dry, then store in airtight jars.

The Bottom Line

Henbit and purple dead nettle are delightful, edible spring plants that are easy to identify once you know the key differences—especially that telltale leaf attachment. Both are safe, nutritious, and useful, and neither one stings (despite the "nettle" name). They're wonderful additions to your spring foraging repertoire and a great way to connect with the changing seasons.

Just remember: if you're looking for the deep mineral nourishment and powerful tonic properties of true nettle, reach for stinging nettle (Urtica dioica)—the real deal that's been used for thousands of years as a nutritive powerhouse. Dead nettle and henbit are lovely in their own right, but they're different plants with different uses.

Happy foraging, and may your spring be filled with purple-topped patches of these cheerful little plants!
