Henbit
Henbit is a mild, non-toxic edible weed - young leaves, tender stems, and purple flowers are all edible raw or cooked. Purple dead-nettle, the plant it is most often confused with, is also edible, so that mix-up is harmless; ground ivy (creeping Charlie) is the one to know apart - strongly minty when crushed, and not a green to eat in quantity. Tell henbit by its upper leaves, stalkless and clasping the stem in scalloped whorls. Only forage from ground free of herbicides and lawn chemicals.
Overview
The purple-flowered mint-family 'weed' that carpets lawns and bare beds in early spring - a mild, tender, free edible green and one of the very first nectar sources for early bees.
Henbit (Lamium amplexicaule) is that low carpet of scalloped green leaves and slender pinkish-purple flowers that turns lawns, gardens, and fallow fields faintly purple in late winter and early spring, often alongside its cousin purple dead-nettle. Most people pull it as a weed, but it is a perfectly good, mild edible green in the mint family - the young leaves, tender stems, and little flowers are all edible raw or cooked, with a gentle, faintly sweet, slightly grassy taste and none of the bitterness of many wild greens.
A cool-season winter annual, henbit sprouts in fall, sits small through winter, then races to bloom in early spring before dying out in summer heat - so it feeds you (and the first bees of the year) in the lean early-spring window when little else is up. Its name comes from chickens' fondness for it. It self-sows freely and is almost always a volunteer rather than a planted crop, but a welcome one: free early greens, edible flowers, and easy identification once you learn to tell it from its equally edible look-alike.

Watch out for
Herbicide / Pollution Contamination Medium
A risk to the forager rather than to the plant. This species grows in lawns, gardens, pastures, croplands, field margins, paths and roadsides - exactly the places that get sprayed with herbicides and lawn chemicals, or that collect road pollution and runoff. The plant itself is harmless; what can make it unsafe to eat is where it has been growing.
Watch for: Plants growing in treated lawns, sprayed beds, pastures or croplands, along busy or polluted roadsides, or anywhere the ground around them looks suspiciously weed-free. Yellowed, twisted or distorted growth on neighboring plants is a sign something has been sprayed recently.
Prevent: Only forage from ground you know has not been treated with herbicides or pesticides, and stay well back from busy roadsides. Ask before harvesting on land you do not manage. If you are not sure, grow your own patch, or gather only from a clean site you have watched across a full season.
Treat: Do not harvest a contaminated plant - there is no washing this off, and no way to tell by looking. The plant itself is fine, so the answer is simply to choose a different site.
Henbit is a lawn and cropland weed, and both settings are commonly sprayed. Early spring, when henbit is at its best, is also when lawn pre-emergents and broadleaf herbicides go down.
Look-Alike Confusion Medium
A common ID mix-up: henbit is routinely confused with purple dead-nettle - both are edible, so that swap is harmless - and, more loosely, with ground ivy (creeping Charlie), which is a different matter and not a green to eat in quantity. Knowing the difference is part of foraging henbit with confidence.
Watch for: Purple dead-nettle has STALKED, triangular, purple-flushed upper leaves; henbit's upper leaves are STALKLESS and clasp the stem. Ground ivy is a low creeping mint that runs on above-ground stems, with round scalloped leaves and a strong minty smell when crushed - that smell is the tell, and it is the one of the three you should not be eating.
Prevent: Check the square stem (mint family), the clasping stalkless upper leaves, and the mild taste; henbit and dead-nettle are both edible, so a mix-up between them is harmless. If it smells strongly minty when crushed, it is not henbit - set it aside.
Treat: No harm between henbit and dead-nettle (both edible). Ground ivy (creeping Charlie) is a different plant - strongly minty-aromatic when crushed, with round scalloped leaves on creeping runners. It contains pulegone (the compound that makes pennyroyal toxic), so do not eat it in quantity, and avoid it in pregnancy. If in doubt about any plant, do not eat it.
Aggressive Self-Seeding & Spread Low
Not a pest but a management issue. This plant sets and sheds seed prolifically, so anything left to ripen builds a persistent seed bank in the soil and returns as a heavy flush of volunteers the following season. Much of that seed stays viable for years, which is why one season of letting it go can take several seasons to undo.
Watch for: Ripe seed heads or stalks shedding onto the ground, and a flush of volunteer seedlings coming up well beyond where the parent plant stood - most obvious in the first weeks of the plant's growing season.
Prevent: Cut, deadhead or harvest the seed heads before they ripen and shatter, which is far easier than dealing with what they drop. Where the plant is grown deliberately, keep it in defined rows or a contained bed so that volunteers are obvious, and site it only where naturalizing is welcome.
Treat: Hoe or hand-pull volunteers while they are small and before they set seed - the existing seed bank will keep germinating for several seasons either way, so this is an ongoing job rather than a single fix. Where the volunteers are themselves edible, harvesting them is the easiest control, but only ever eat or grow on a seedling you can positively identify.
Henbit completes its cycle fast and reseeds prolifically as a cool-season weed. It is shallow-rooted and easy to pull, and harvesting it is the pleasant version of weeding it.

Low patches of scalloped stalkless upper leaves whorled around square stems, topped with pinkish-purple tubular flowers.
The common henbit dead-nettle: a low cool-season winter annual with square stems, scalloped rounded leaves that clasp the stem in whorls, and slender pinkish-purple tubular flowers. A mild, tender, edible early-spring green and early bee plant.
Grow
A cool-season self-sower of moist, disturbed ground; you rarely plant it - it volunteers - and it thrives with no care, fading when summer heat arrives.
Henbit grows itself in the cool, moist part of the year, favoring the rich, disturbed soil of garden beds, lawns, croplands, and roadsides in full sun to part shade. It is a cool-season winter annual: it germinates in fall, overwinters as a low clump, blooms early in spring, and dies off as summer heat sets in - so it fills the off-season and shrugs off frost.
You almost never plant henbit; it volunteers abundantly from self-sown seed. If you want it deliberately as an early salad green, surface-sow the seed in fall or earliest spring into cool, moist soil and it comes up on its own timetable with no care. Far more often the 'growing' question is whether to welcome it as a free green and early bee plant or to pull it (it is shallow-rooted and easy to remove) before it seeds. Either way it asks nothing of you but harvesting - and a little management if you want it out of a tidy lawn.
Harvest
Snip the tender tops and flowers with scissors through the cool season - it is cut-and-come-again - and eat them raw or lightly cooked; harvest young, before it bolts in heat.
Harvesting henbit is simple: gather the young leaves, tender upper stems, and purple flowers with scissors while the plant is lush and cool-season fresh. It is cut-and-come-again - snip the tops and it regrows for repeated pickings through fall and, especially, late winter into spring. Take it young, before warm weather makes the stems stringy and fibrous and before it sets heavy seed.
Henbit's mildness makes it easy to enjoy raw - toss the tender tops and flowers into salads and sandwiches, or blend them into a green smoothie - and it is also good lightly cooked, wilted like a delicate green into eggs, soups, or a saute (it does not need much heat). Only forage from ground free of herbicides and lawn chemicals, and take a moment to confirm the ID: henbit's square stem marks it as a mint-family plant, and its scalloped upper leaves clasp the stem directly (unlike purple dead-nettle's stalked, triangular upper leaves) - though both are edible, so a mix-up is harmless.
Nutrition
A nutritious free green carrying iron, vitamins, and fiber, best enjoyed as an early-spring tonic green when garden vegetables are scarce.
Like many wild greens, henbit is more nutritious than its humble weed status suggests. Its tender leaves and stems supply iron, fiber, and vitamins along with beneficial plant compounds, all in a mild, low-calorie package that is easy to eat raw and in quantity - a genuinely useful free food in the early-spring window when little from the garden is ready. As a member of the mint family it also carries mild aromatic compounds, though its flavor is gentle rather than minty.
Because it is so mild and tender, henbit is best thought of as a fresh early-season tonic green - a way to work more leafy greens into cool-weather meals when other sources are thin. Ecologically it earns its keep too: its very early flowers are an important nectar and pollen source for the first bees of the year. Nutritious, gentle, and free, henbit rewards a second look from anyone who has only ever thought of it as something to weed out.
In the kitchen
A mild raw salad green and edible flower; also good wilted into eggs, soups, and sautes, or blended into smoothies and pestos.
Henbit's gentle, faintly sweet flavor makes it one of the more kitchen-friendly wild greens. Raw, the tender tops and little flowers go into salads, sandwiches, and wraps, or scatter the purple blooms over a plate as a pretty edible garnish. Blended, it works in green smoothies and can stand in for part of the greens in a pesto (its mild taste plays well with garlic, nuts, and cheese).
Cooked, treat it like a delicate spinach or other tender green: wilt it into scrambled eggs and omelets, stir it into soups and broths at the end, fold it into a quick saute, or add it to savory pancakes and fritters. It needs only brief heat. Because henbit is so mild, it rarely dominates a dish - it is a way to add free, fresh, seasonal greens rather than a bold flavor of its own. Pick it young and cool-season for the best texture, since older, warm-weather growth turns stringy.
History
A Eurasian plant carried worldwide with agriculture and long known as a chicken-loved cool-season weed and folk green, now rediscovered by foragers as free early-spring food.
Henbit is native to Europe, Asia, and North Africa and has traveled with people and agriculture around the world, becoming one of the most common cool-season weeds of croplands, gardens, and lawns across North America. Its curious common name - 'henbit' - records an old observation: chickens love to eat it, pecking at the tender greens, and it has long been valued as free poultry forage as well as a folk green for people.
As a member of the vast and useful mint family (Lamiaceae) - the square-stemmed group that also gave us basil, thyme, and oregano - henbit appears in the long tradition of eating early-spring wild greens as a fresh tonic after winter. For most of its modern history in North America it has simply been an overlooked weed of the cool season. The recent revival of foraging has restored some of its old reputation, reminding gardeners that the purple carpet underfoot in early spring is free, mild, nutritious food - and one of the year's first meals for the bees.
Troubleshooting
Confirm the easy mint-family ID (and that it is not the equally edible dead-nettle), harvest young before it bolts, and pull it easily where you do not want it.
Is this henbit or purple dead-nettle? Both are edible mint-family weeds, so a mix-up is harmless, but to tell them apart: henbit's upper leaves are stalkless and clasp the square stem in scalloped, rounded whorls, and its plants look greener; purple dead-nettle's upper leaves are stalked, triangular, and flushed purple, forming a fuzzy purple-topped 'steeple.' It is tough and stringy: you harvested it late or in warm weather - take it young in the cool season. It is everywhere in my beds and lawn: henbit self-sows prolifically each cool season - pull it (it is shallow-rooted and easy) before it flowers and seeds, or simply harvest and eat it. It disappeared in summer: normal - it is a cool-season winter annual that dies back in heat and returns from seed in fall. Is it safe? Henbit itself is non-toxic, and the plant it is usually mixed up with - purple dead-nettle - is edible too, so that swap is harmless. Check the plant rather than trusting the family, though: ground ivy (creeping Charlie) creeps through the same lawns and beds, smells strongly minty when crushed, and is not a green to eat in quantity. And only forage herbicide-free ground. Pests and diseases: essentially none.
Growing across climates
A cool-season weed adapted across the country (zones 3-10); it shifts its season by climate - winter-growing in the South, fall and spring in the North - and always fades in summer heat.
Henbit is naturalized across essentially all temperate North America, zones 3-10, and adapts by shifting when it grows rather than where. Cold northern zones (3-6): it germinates in fall or very early spring and blooms as soon as the weather softens, giving early-spring greens and one of the first flowers of the year before summer heat ends it. Mild and southern zones (7-10): it behaves as a true winter plant, carpeting gardens, fields, and lawns green and purple through the cool months and dying out as heat arrives. Everywhere, its requirement is cool, moist conditions; it bolts and fades quickly in heat and drought.
Because it is so widely adapted, henbit turns up as a foraged early-spring green almost anywhere people live - you simply look for it in the cool part of the year. In the North that means early spring; in the South, the depths of winter. Either way it is a dependable, mild, free green in the season when garden vegetables are scarce, and a reliable early nectar plant for pollinators across the whole country.
