Introduced - native to Europe and western Asia

The flowers are a safe, gentle tea for most people. As a daisy-family plant, chamomile can rarely trigger reactions in people highly allergic to ragweed and other Asteraceae; strong medicinal doses are traditionally avoided in pregnancy. Do not use it as an eye wash. If you take warfarin or another anticoagulant, talk to your prescriber before drinking chamomile regularly - it may increase bleeding risk.

Overview

The tea chamomile: an easy, knee-high annual that blooms for weeks, self-sows itself back every spring, and dries into a winter's worth of sweet, apple-scented bedtime tea.

This is German chamomile (Matricaria chamomilla), the chamomile of the teapot — an upright annual that grows about knee-high, covers itself in small white-and-gold daisies from early summer, and produces the sweeter, more aromatic flowers that make up nearly all the dried chamomile sold anywhere. It is one of the easiest herbs in the garden: sow it on the surface of cool spring soil, leave it alone, and pick flowers for weeks.

Two things about it surprise new growers. It is an annual that behaves like a perennial, because it self-sows so freely that one planting usually returns on its own every spring. And there is a second, different plant sold under the same name: Roman chamomile (Chamaemelum nobile) is a low creeping perennial grown as a fragrant groundcover and lawn, with more bitter flowers — it has its own page here. If you want tea, this is the one. Its name comes from the Greek for 'ground apple', which is exactly what a warm patch of it smells like.

When to plant

Mar 20 – Apr 24
Primary Direct sowSpringsow again every 21 days
Surface-sow into cool soil - the seed needs light to germinate and the plant tolerates light frost, so sow early rather than waiting for warmth.
Feb 27 – Mar 13
Secondary Start indoorsSpring
Start seed indoors for transplants; surface-sow under light and don't bury the fine seed.
Mar 27 – May 1
Secondary TransplantSpring
Set out indoor-grown or bought transplants from a couple of weeks before last frost; young chamomile takes light frost, and going out early gives a longer bloom before summer heat.

Zone 7a typical frost: last Apr 10 · first Oct 25 (spring frost runs Mar 27–Apr 24 in a typical spread of years)

Life stages

  1. Germination day 0–12 from sowing
    • Surface-sow - the seed needs lightevery 1 d
      Scatter the tiny seed on the soil surface and press it in without covering; chamomile seed needs light to germinate. Mist to keep it moist and it sprouts in 1-2 weeks.
    • Sow into cool soil
      Chamomile germinates and grows best in cool weather; it tolerates light frost, so it can go out early in spring.
    Seed washing away (it is tiny - mist gently, don't blast)Slow germination in cold soil (normal)
  2. Seedling day 12–35 from sowing
    • Thin to 8-10 inches apart
      Give the upright plants room to bush out and flower heavily; crowded chamomile stays thin and mildews. Transplant the thinnings elsewhere rather than wasting them.
    • Keep seedlings moist to establish
      Water young plants steadily; once established, chamomile is quite drought-tolerant and thrives on a little neglect.
    Damping off in cold, wet soilAphids on tender shoots
  3. Leafing out day 35–60 from sowing
    • Water lightly; don't overfeed
      Chamomile prefers lean soil and even moisture. Skip heavy fertilizer - rich ground grows floppy foliage and fewer, weaker-scented flowers.
    • Keep the patch weeded while young
      The feathery seedlings are easily crowded early on; once they fill in they hold their own.
    Floppy, leggy growth (too much shade or nitrogen)Powdery mildew starting in humid, crowded stands
  4. Bloom & flower harvest day 65–150 from sowing
    • Pick flowers fully open, petals still flat or just curling backevery 3 d
      Harvest the little daisy flowers when the white petals are horizontal or just beginning to reflex and the yellow center is domed. Pinch or comb them off - the more you pick, the more it blooms.
    • Enjoy the pollinators
      Chamomile flowers draw bees, hoverflies, and tiny beneficial wasps that hunt aphids - a reason to keep a patch blooming near the vegetables.
    Flowers going over and browning (past their prime - harvest on time)Petals fully reflexed and center pollen-dusty (slightly past ideal for tea)
  5. Seed set / self-sow day 95–150 from sowing
    • Let a few flowers go to seed for next year
      German chamomile self-sows freely. Leave some late flowers to ripen and drop seed, and a fresh patch returns on its own - or collect the dried seedheads to sow deliberately.
    • Decide now whether to let it self-sow
      Seedlings come up wherever the seed falls, which is a free patch next spring or a weed in the wrong bed. Leave the seedheads where you want it back, and deadhead or pull the spent plants where you do not.
    Plants finishing and self-seeding (welcome it, or deadhead to contain the patch)Spent stems browning and falling over (pull them once the seed has dropped)

Watch out for

Powdery Mildew Medium DiseaseJul, Aug, Sep

Powdery mildew is a fungal disease that coats leaves - and often stems, buds, and fruit - in a white-to-gray powder that looks like spilled talcum. It is not one fungus but a large family of them, each fairly specialised to its own group of plants, which is why mildew on one crop rarely jumps to an unrelated one beside it. Unlike most leaf diseases it does not need wet leaves: it thrives on warm dry days followed by humid nights, and it takes hold fastest where plants stand crowded in still air or in shade. The coating blocks light, so heavily covered leaves yellow, brown, and drop early. On many plants that is mostly disfiguring and arrives late enough not to matter; where it strips away the leaves a crop still needed to finish, it costs you size, sweetness, and quality.

Watch for: Round white powdery spots on the upper leaf surfaces that spread and merge until whole leaves look dusted. It usually starts on the oldest, lowest, most shaded leaves and works upward, so check there first. Look at the undersides too, and at stems, buds, and flower stalks, which get coated as it advances. Leaves that yellow, brown, curl, or go crisp and drop early under the coating. New growth that opens small, crumpled, or twisted where the fungus has reached the shoot tips. On plants where it gets onto the fruit, a dull gray film, russeted or scarred skin, and cracking. Late in the season, tiny dark specks scattered through the white felt - that is the fungus setting up to overwinter on the debris.

Prevent: Give plants room. Crowding and still air are the biggest single driver, so space at the full recommended distance, thin seedlings properly, and divide or prune out congested growth until air moves through the plant. Full sun and an open position help; deep shade and a still corner against a wall are where it always starts. Water at the base rather than overhead, and water early in the day so nothing stays damp overnight. Keep plants evenly watered - drought stress at the roots leaves them far more susceptible, even though the fungus itself likes dry air. Go easy on nitrogen, since soft lush growth is the most vulnerable. Where resistant varieties exist for what you are growing, choosing one is the single most effective thing you can do on a plant that mildews every year. Clear infected leaves and stems away at the end of the season rather than composting them.

Treat: Start early: sprays protect healthy tissue, they do not clean up leaves that are already coated. Pick off and bin the worst leaves as soon as you see them, and open the plant up by thinning or pruning so air moves through. On anything that regrows quickly, shearing the whole plant back forces a clean flush and beats spraying. If it keeps spreading, potassium bicarbonate, horticultural oil, or neem applied weekly will hold it - cover both leaf surfaces. Sulfur also works, but it burns the foliage of some plants, should never go on in heat, and must not be mixed with or applied close behind an oil spray. Whatever you use must be labeled for the plant you are treating: follow that label and observe its pre-harvest interval on anything you eat. Do not compost badly infected material. Late-season mildew on a plant that is finishing anyway is usually cosmetic; on a crop still filling out it is worth acting on.

Common on aging, overcrowded stands late in the season. Shear the patch back or pull spent plants - self-sown replacements usually follow on their own.

Aphids Low PestApr, May, Jun, Jul

Aphids are small soft-bodied sap-suckers - green, black, gray, pink, or waxy white, and mostly wingless - that gather in dense colonies on the tenderest new growth: shoot tips, buds, and the undersides of young leaves. They breed extremely fast in mild weather, so a few can become hundreds inside a week. Their feeding curls and distorts soft growth, and the sticky honeydew they excrete coats everything below and turns black with sooty mold. Ants often farm and defend the colonies for that honeydew. A few aphids are normal on almost any plant and a healthy plant shrugs them off; only dense, persistent colonies do real damage, and some aphids also spread plant viruses as they feed.

Watch for: Dense clusters of tiny insects packed onto shoot tips, flower buds, and the undersides of young leaves. Curled, cupped, or distorted new growth that never opens properly. A sticky shine on the leaves - and on whatever sits under the plant - that later goes black with sooty mold. Tiny white cast skins left behind where a colony has been feeding. Ants running steadily up and down the stems, which is often the first thing you notice. Mottled, streaked, or misshapen leaves that do not grow out can mean a virus the aphids brought with them rather than the feeding itself.

Prevent: Go easy on nitrogen: the soft, lush growth that heavy feeding produces is exactly what aphids breed on. Check new growth once a week through spring and early summer so you catch colonies while they are still small, and rub the first few out with your fingers. Leave flowering plants nearby and skip broad-spectrum sprays - ladybugs, lacewings, hoverflies, and parasitic wasps do most of this work for free, and they only stay if there is something for them to eat. Keep ants off the plant where you can, since they protect aphids from those predators. Water steadily so plants are not stressed, and check any new plant over before you bring it home or move it indoors, since aphids usually arrive on something else.

Treat: Knock the colonies off with a hard jet of water and repeat every few days - on most plants that alone ends it. Pinch out or prune off the worst-infested tips rather than treating the whole plant. If colonies keep rebuilding, spray insecticidal soap or horticultural oil directly onto the insects, covering leaf undersides, and repeat weekly until they are gone; treat early or late in the day, and never spray a wilted or heat-stressed plant. Avoid broad-spectrum insecticides - they kill the ladybugs, lacewings, and parasitic wasps that were about to solve the problem for you, and aphid numbers usually come back worse afterward. Anything you spray must be labeled for the plant you are treating; follow that label and observe its pre-harvest interval. On anything you eat, wash leaves, heads, and buds well before use, since aphids hide down in crowns, folds, and tight growth.

Letting some flowers open recruits the hoverflies and lacewings whose larvae clear aphids, and a hard cutback with clean regrowth also resets an infested plant.

Gray Mold (Botrytis) Low DiseaseMay, Jun, Sep, Oct

Botrytis cinerea and its relatives - the fuzzy gray-brown mold of cool, wet, humid weather. It blights flowers and buds, rots ripening fruit, and moves into soft, aging, bruised or frost-damaged tissue through the smallest wound, coating whatever it kills in dusty gray spores. It overwinters on dead plant debris, spreads on air currents and by direct contact between touching tissue, and keeps working after harvest, which is why it also ruins fruit and bulbs in storage.

Watch for: Browned, collapsed flowers and buds; soft, water-soaked brown patches on leaves, stems or fruit; and a dusty gray-brown fuzz over the dead tissue. Rot jumping between two pieces of fruit or two petals that touch is the signature, and it often shows up again in the fridge or the storage box days later.

Prevent: Space and prune for airflow, water at the base rather than over the top, and go easy on nitrogen, which produces the soft growth it prefers. Clear dead leaves, spent flowers and rotting fruit at every pass, since that debris is where it overwinters. Handle fruit, buds and bulbs gently, because it enters through bruises, and cure and store anything you keep dry and well ventilated.

Treat: Cut out and destroy infected tissue as soon as it appears, and bag it rather than composting it. Harvest ahead of a prolonged wet spell and store the crop dry and cold. Protective fungicides help through long damp weather, but airflow and sanitation do most of the work.

The risk on chamomile is at harvest - flowers picked damp and piled up will mold instead of drying. Pick in dry conditions and spread them out thinly so they dry fast.

Thrips Low PestJun, Jul, Aug

Tiny slender sap-sucking insects that rasp at leaves, buds and petals and drink what runs out, leaving silvery-white streaking and fine flecking, brown scorched patches, and new growth that comes out twisted or fails to open. They breed fast in hot, dry weather, shelter deep in leaf sheaths, folds and unopened buds where sprays struggle to reach, and several species also transmit plant viruses - which is often more damaging than the feeding itself.

Watch for: Silvery-white streaks and fine speckling on leaves and petals, brown discolored patches, distorted buds and blooms that fail to open properly, and tiny sliver-like insects that drop out when you shake foliage or a flower over a sheet of white paper. Worst in hot, dry spells and on drought-stressed plants.

Prevent: Scout early, before the damage reaches the part of the plant you care about. Start with clean planting stock, keep plants well watered since drought-stressed plants suffer worst, avoid heavy nitrogen, clear weedy hosts nearby, and hang blue or yellow sticky traps to catch the first arrivals. Reflective mulch deters them, and predatory mites, lacewings and minute pirate bugs do real work outdoors.

Treat: A strong water spray dislodges light infestations, and on a plant that can take it a hard shear and clean regrowth clears them outright. For heavier pressure use insecticidal soap, neem or spinosad, aimed down into the leaf sheaths and buds where thrips actually shelter, and repeat at intervals since eggs and pupae escape a single spray. Spinosad is a registered insecticide: use only a product labeled for the crop you are treating, follow the label exactly, and observe its pre-harvest interval.

Cosmetic on chamomile rather than serious - the flecking arrives with hot dry weather and the plant grows straight through it. A hard shear and regrowth clears them.

Grow

Surface-sow the fine seed into cool spring soil - it needs light to germinate - then thin to 8-10 inches and grow it lean and sunny.

Chamomile grows from very fine seed that needs light to germinate — scatter it on the surface and press it in without covering, then keep it misted until it sprouts in one to two weeks. Sow into cool soil in early spring, three weeks or so before your last frost; the seedlings tolerate light frost and the plant much prefers cool weather to summer heat, so sowing early buys you a longer bloom. You can also start it indoors 4-6 weeks ahead and set transplants out around last frost.

It isn't fussy about soil and in fact prefers it on the lean side — rich, heavily fed ground grows floppy plants with fewer, weaker-scented flowers. Thin or space plants 8-10 inches apart so each can bush out and air can move through the patch. Full sun gives the most flowers, though a little afternoon shade helps in hot climates. Sow a second batch three weeks after the first if you want the harvest to run longer, and leave a few late flowers to seed so the patch comes back by itself.

Care

Nearly carefree: lean soil, even water, no heavy feeding; the real job is picking flowers often, then deciding whether to let it self-sow.

Chamomile thrives on a little neglect. Water young plants to establish them, then only in dry spells — it is notably drought-tolerant once rooted. Don't over-fertilize: lean soil produces sturdier plants and more aromatic flowers, while rich ground grows lush foliage at the expense of bloom. Keep the patch weeded while the seedlings are small; once it fills in, it holds its own.

The main job is picking flowers, and it is the one that matters — steady harvesting keeps the plant blooming for weeks, while a patch left unpicked sets seed and winds down early. Tall plants can flop after rain, especially in rich soil or wind; grow them leaner and closer together and they hold each other up. At the end of the season, decide whether to let it self-sow (leave some flowers to ripen and drop for a free return patch) or to deadhead and pull the spent plants to keep it where you want it. That is genuinely the whole of the care.

Harvest

Pick the daisy flowers fully open, petals flat or just curling back; a fine-toothed comb or your fingers strips them fast.

Harvest chamomile flowers when they are fully open — the white petals horizontal or just beginning to curl backward and the yellow center domed and fragrant. That is the peak for both flavor and the aromatic oils; wait too long and the petals fully reflex, the centers go to pollen and seed, and the tea turns weaker and more bitter. Pick in the morning after the dew dries.

For a big patch, a chamomile rake or fine-toothed comb combs the little flowers off quickly; for a few plants, just pinch them off between finger and thumb. Frequent picking encourages more bloom, so harvest every few days at the peak of the season — a well-picked patch keeps flowering for weeks longer than one left alone. Use the flowers fresh or dry them for storage.

Storage

Dry the flowers whole and store airtight - dried chamomile keeps its calming aroma for a year, ready for tea all winter.

Chamomile dries beautifully, which is how most of it is used. Spread the freshly picked flowers in a single layer on a screen or tray somewhere warm, dry, and airy (or use a dehydrator on low), and let them dry until crisp — usually one to two weeks air-drying. The flowers should crumble lightly and keep their sweet, apple-hay scent.

Store the dried flowers whole and airtight, out of light, and they hold their aroma and gentle potency for about a year — a jar of homegrown chamomile is a winter's worth of bedtime tea. You can use flowers fresh, too (use about twice as many as dried for a cup), but drying is the way to carry a summer's harvest through the year. Dried flowers also infuse into oils and hair rinses.

Propagation & seed saving

It self-sows itself into a permanent patch - leave a few late flowers to seed, or collect the dried seedheads and sow them where you want it.

Chamomile practically propagates itself. It self-sows so reliably that a single first-year planting usually returns on its own every spring — let a few late flowers ripen and drop their seed and you will find a fresh crop of feathery seedlings the following season, often earlier and stronger than anything you sow deliberately. That is the whole trick: this is an annual you plant once.

To take charge of it, collect the dried seedheads once they brown, rub them out over a bowl, and store the fine seed cool and dry — it stays viable for a few years. Scatter it where you want next year's patch, or sow it in succession three weeks apart for a longer harvest. Chamomile is open-pollinated and comes true from saved seed, so a plant you liked gives you more of the same. Thin or move the volunteer seedlings while they are small; they transplant easily at that stage and sulk once they have started to flower.

Nutrition

Consumed as a flower tea rather than a food, chamomile's value is its aromatic and antioxidant compounds, not calories or vitamins.

Chamomile is taken almost entirely as a flower tea, not eaten as a food, so it isn't a source of calories, vitamins, or minerals in any meaningful amount. Its value is in its plant chemistry: the flowers are rich in flavonoid antioxidants (notably apigenin) and aromatic oils — including the blue compound chamazulene and bisabolol in German chamomile — that carry both the apple scent and the herb's calming and anti-inflammatory reputation.

Those same compounds are why a cup of chamomile tea is a caffeine-free, antioxidant-bearing drink rather than an empty one. Think of chamomile as a soothing herbal infusion that delivers gentle plant compounds and a moment of calm, rather than as nutrition in the dietary sense — its worth is in the experience and the mild bioactive oils, not on a nutrition label.

In the kitchen

Chamomile is tea first - a sweet apple-scented infusion - but also flavors baked goods, syrups, and even a Spanish sherry.

Chamomile's culinary home is the teacup. Steep a tablespoon of dried flowers (or a small handful of fresh) in hot water for five minutes for the classic sweet, apple-hay, faintly honeyed infusion — the quintessential bedtime tea, lovely with a little honey and served hot or iced. This is the species that makes that cup: sweeter and less bitter than the perennial Roman chamomile.

Beyond tea, the flowers' apple-honey flavor works in the kitchen: infuse them into syrups and honey for cocktails and lemonade, steep them into cream or milk for panna cotta, ice cream, and custards, or fold them into shortbread and cakes. In Spain, chamomile even flavors a style of sherry (manzanilla, 'little apple'). Use it with a light hand — too much or over-steeped turns bitter — and pair it with honey, lemon, apple, and vanilla, all of which flatter its gentle floral sweetness.

Traditional & historical uses

One of the best-loved and best-documented calming herbs in the world: a genuine, gentle tradition for sleep, anxiety, and digestion, backed by real (if modest) evidence.

This section records how people have traditionally used this plant, and what is known about the risks. It is history and general information — not medical advice, and not a recommendation to treat anything. Plants are not dosed like medicines, some interact with prescriptions, and some are harmful in ways that are not obvious. Talk to a clinician before using any plant medicinally.

Chamomile is among the most widely used medicinal herbs on earth, and its calming reputation is well earned. For thousands of years it has been drunk as a gentle remedy for restlessness, mild anxiety, and sleeplessness, and to settle upset stomachs, colic, and indigestion — a soothing bedtime tea in nearly every European household. Modern research supports a modest version of this: the flavonoid apigenin binds calming receptors in the brain, and small clinical studies suggest chamomile can gently ease anxiety and improve sleep quality, while its bisabolol and chamazulene oils have documented anti-inflammatory activity.

Topically and traditionally it is used as an anti-inflammatory wash for irritated skin and as a mouth rinse or gargle, and as a hair rinse to lighten and brighten fair hair. Honest framing: the effects are real but gentle and food-level — a genuinely soothing tea, not a sedative drug. The main caution is allergy: people highly sensitive to ragweed and the daisy family can react, and strong medicinal doses are traditionally avoided in pregnancy. Do not use chamomile as an eye wash — the eye is the one route with documented allergic conjunctivitis and swelling in ragweed- and daisy-sensitive people, and a home infusion is not sterile. One interaction is worth knowing: if you take warfarin or another anticoagulant, talk to your prescriber before drinking chamomile regularly, since it may increase bleeding risk. As calming herbs go, chamomile is one of the safest and most pleasant you can grow and steep.

History

The 'ground apple' of the ancient Mediterranean and Egypt, revered as a healing and calming herb for millennia and a fixture of every physic and cottage garden.

Chamomile has been used for at least four thousand years. The ancient Egyptians revered it, dedicating it to the sun god Ra and using it in remedies and embalming; the Greeks named it chamaimelon, 'ground apple,' for the sweet apple scent of its low-growing flowers. Greek and Roman physicians prescribed it for fevers, digestion, and the nerves, and it spread through the medieval physic gardens and cottage borders of Europe as a heal-all and a strewing herb whose crushed flowers freshened floors.

German chamomile became the commercial tea and pharmacy herb of continental Europe — grown by the field in Germany, Hungary, Poland, and Egypt, distilled for its blue oil, and stocked in every apothecary. (The English 'lawn' chamomile of Tudor seats and scented paths is a different species, Chamaemelum nobile, with its own page here; the two were used and confused interchangeably for centuries.) Carried worldwide by settlers, chamomile remains one of the most popular herbal teas on the planet, its calming reputation intact across the centuries.

Growing across climates

A cool-season, frost-tolerant annual that grows almost anywhere; summer heat, not cold, is what ends it, so warm climates flip it to the fall and winter season.

Zones 3-6: easy — a hardy, self-sowing annual that takes hard frost as a seedling, so it can be sown weeks before the last frost and often returns from its own dropped seed. Zones 7-8: easier still, with a longer season; self-sown seedlings frequently overwinter as small rosettes and bloom early the following spring. Zones 9-10: flip it to the cool season — sow in fall for winter and spring bloom, because intense summer heat pushes the plants over quickly and the flowers lose their sweetness. Zones 11+: a cool-season annual only, grown in the mildest months with some afternoon shade.

Across the map the rule is the same: chamomile is a cool-weather plant. It flowers best in spring and autumn and simply times itself to whichever season stays mild where you live. Humidity is the other limit — a crowded, damp, still patch mildews in late summer wherever it is grown, so give it space and sun.

Troubleshooting

Few flowers usually means too much shade or rich soil; white coating is powdery mildew from crowding; floppy plants want leaner ground; bitter tea means over-steeping or over-mature flowers.

Lots of foliage, few flowers: too little sun or too much fertilizer — give full sun and grow it lean, since rich soil favors leaves over blooms. White powdery coating on leaves (powdery mildew): crowding and humidity — thin and space for airflow and avoid overhead watering. Floppy, sprawling plants: overly rich soil, shade, or wind on tall stems — grow leaner and in more sun, or give light support. Bitter tea: over-steeping or over-mature flowers — pick them just-open rather than reflexed and pollen-dusty, and steep about five minutes rather than ten. The whole patch finishing early: summer heat, or flowers left unpicked to set seed — sow earlier, sow again in succession, and keep picking. Silvery speckled leaves (thrips) or sticky shoots (aphids): usually minor — a hard cutback and the beneficial insects chamomile attracts keep them in check.
