Is Chamomile a Perennial? Two Plants, Two Answers

Roman chamomile is a perennial that spreads; German chamomile is an annual that self-seeds. Both come back — by completely different mechanisms.

Both answers are correct, for different plants. Roman chamomile is a perennial. German chamomile is an annual that self-seeds so freely nobody notices.

Telling them apart

Two different plants with one common name
Roman chamomileGerman chamomile
Botanical nameChamaemelum nobileMatricaria chamomilla
Life cyclePerennialAnnual (self-seeds)
Height10–30 cm50–60 cm
HabitLow spreading matUpright, branching
FoliageSoft, dense, strongly apple-scentedFiner, sparser
Flower centreFlat-ish, solidConical, hollow
Flowers per plantFewMany
FlavourMore bitter, medicinalSweeter, apple-like
Best forLawns, paths, ground coverTea

The hollow cone is the definitive test

Pick a flower and slice the yellow centre in half.

German chamomile’s centre is conical and hollow inside. Roman chamomile’s is flatter and solid. Nothing else distinguishes them as reliably, and it works even on a plant that is not yet in full growth.

“Comes back” means two different things

Roman chamomile overwinters as a living plant. The mat persists, spreads outward from established roots, and gets wider every year. You can divide it, move it, and expect the same individual plants for years.

German chamomile dies completely after flowering. What returns is the next generation, germinating from seed dropped the previous summer. The patch persists; the plants do not.

That distinction has one practical consequence worth acting on:

  • Let German chamomile set seed if you want it next year. Deadheading the whole plant ends the colony
  • Deadhead Roman chamomile freely — it costs nothing, since the plant itself persists

Growing either one

Both want much the same conditions, which are not the rich moist conditions people often assume:

  • Full sun — part shade at a push in hot regions
  • Free-draining soil. Both dislike waterlogging, Roman particularly
  • Poor to average fertility. Rich soil produces leafy plants with fewer flowers
  • Light watering. Established plants are fairly drought-tolerant
  • No feeding beyond a scrape of compost

German chamomile is sown direct in spring, barely covered — it needs light to germinate, so burying the seed is a common reason it fails. Roman chamomile is usually bought as plants or divisions, since ‘Treneague’ produces no seed at all.

The chamomile lawn, honestly

It is a genuinely lovely thing and a frequently disappointing one.

What it needs:

  • Roman chamomile ‘Treneague’ — non-flowering, so no mowing
  • Full sun
  • Sharply drained soil
  • Light traffic only
  • Hand weeding, since nothing selective can be used on it

What it is not: a lawn substitute. It will not take children, dogs, football or a garden party, and it thins badly under repeated walking. A chamomile path, a seat, or a panel set within paving all work far better than a chamomile lawn, because each keeps the traffic occasional.

Harvesting for tea

German chamomile, almost always:

  1. Pick flowers fully open, on a dry morning after the dew has gone
  2. Pick often — the more you take, the more the plant produces
  3. Dry on a tray somewhere warm, dark and airy for one to two weeks
  4. Store airtight once completely dry and crisp
  5. Expect a lot of picking. Dried flowers weigh very little, so a useful supply takes a substantial patch and repeated harvesting through the season

Common questions

Is chamomile a perennial or an annual?

Both, depending which chamomile you mean. Roman chamomile, Chamaemelum nobile, is a low-growing hardy perennial that forms a spreading mat and returns from the same roots each year. German chamomile, Matricaria chamomilla, is an annual that completes its life cycle in one season — but it self-seeds so prolifically that it reappears in the same spot year after year and is frequently assumed to be perennial. Most seed sold for tea is German chamomile; most plants sold for chamomile lawns are Roman.

Which chamomile is better for tea?

German chamomile, in most people's view, and it is what the overwhelming majority of commercial chamomile tea is made from. It produces far more flowers per plant, grows upright to 50 to 60 cm, and has the sweeter, apple-like flavour associated with chamomile tea. Roman chamomile is usable and has a more bitter, slightly medicinal note that some prefer and many do not, and its low mat habit yields far fewer flowers for the space it takes.

Which chamomile is used for a chamomile lawn?

Roman chamomile, and specifically the non-flowering cultivar 'Treneague', which spreads as a dense mat and does not need mowing because it produces no flowers. Flowering Roman chamomile can be used but requires trimming after bloom. German chamomile is entirely unsuitable — it is an upright annual that dies at the end of the season and would leave bare ground. A chamomile lawn also only works in light traffic, free-draining soil and full sun.

Does chamomile come back every year?

Yes in both cases, by different routes. Roman chamomile regrows from established roots and spreads outward, becoming a wider patch each year. German chamomile dies after flowering but drops enormous quantities of seed, which germinates the following spring in the same area — so the plants are new individuals even though the patch persists. The practical difference is that letting German chamomile set seed is essential, whereas deadheading Roman chamomile costs you nothing.

How do you tell Roman and German chamomile apart?

Look at the habit and the flower centre. Roman chamomile grows low, 10 to 30 cm, forming a spreading mat with soft feathery foliage that smells strongly of apple when crushed, and its flower centres are relatively flat and solid. German chamomile grows upright and branching to 50 to 60 cm with finer, sparser foliage, and its flower centres are distinctly conical and hollow — a detail that is diagnostic if you cut one in half.
