Chamomile is the herb you grow for its flowers—those tiny white-petaled, golden-centered daisies that dry into the world’s most soothing cup of tea. Two plants share the name and the apple-sweet fragrance, but they behave differently in the garden. German chamomile (Matricaria chamomilla) is a tall, branching annual that reseeds itself and gives the heaviest flower harvest. Roman chamomile (Chamaemelum nobile) is a low-growing perennial that spreads into a fragrant mat, prized as a groundcover and a tea source both. Either one is genuinely easy: chamomile germinates readily from seed, asks for little water once growing, and rewards you with weeks of bloom you can pick by the handful. This guide covers choosing between the two, sowing, spacing, care, and the daily picking that keeps flowers coming.
Key Takeaways
- German chamomile is a tall reseeding annual; Roman chamomile is a low perennial groundcover (zones 4–9).
- Surface-sow seed in spring—it needs light to germinate, so don’t bury it.
- Give full sun (part shade in hot climates) and average, well-drained soil; chamomile prefers lean ground.
- Water moderately—about 1 inch a week—and avoid overfeeding, which reduces flowering.
- Harvest the flower heads when petals are flat or just starting to bend back, picking every few days.
- Let a few flowers go to seed and German chamomile will return on its own each year.
German vs. Roman Chamomile
Decide which you want before you buy seed, because they suit different goals. German chamomile grows 1 to 2 feet tall, branches heavily, and pumps out hundreds of small flowers—it is the production workhorse for anyone who wants a real tea supply. As an annual it dies at season’s end but reliably reseeds, so a patch tends to persist year after year without replanting. Roman chamomile stays low, 3 to 12 inches, and creeps outward into a dense mat that releases scent when walked on, making it a classic choice for a fragrant lawn alternative or path edging. It is a true perennial, hardy in USDA zones 4 to 9, though it flowers less heavily than the German type. For tea, German is the usual pick; for a living groundcover that also yields some flowers, Roman wins. Both make charming ornamental edges—see the Plants & Flowers hub for more flowering herbs.
Sowing Chamomile
Chamomile seed is dust-fine and needs light to germinate, so the cardinal rule is do not cover it. Sprinkle seed on the surface of moist soil and press it in lightly with your hand. You can start indoors 6 to 8 weeks before the last frost—scatter on the surface of seed-starting mix, keep at 65 to 70°F and bright, and expect sprouts in 7 to 14 days—or direct-sow in the garden in early spring once the soil can be worked. Direct sowing is simplest because chamomile resents transplanting if its taproot is disturbed; sow into the spot where it will grow.
For German chamomile, thin or space plants 8 to 12 inches apart—they branch widely and fill in. Roman chamomile can go a bit closer, 6 to 9 inches, so it knits into a continuous mat. Seedlings start small and slow, so keep the bed weeded early; once chamomile gets going it largely outcompetes weeds on its own. A spring and a late-summer sowing of German chamomile can stretch your harvest across most of the growing season.
Light, Soil, and Water
Chamomile flowers best in full sun—six or more hours—though in hot southern climates a little afternoon shade keeps it from frying and bolting. It is genuinely unfussy about soil and actually prefers lean, well-drained ground; rich, heavily amended beds push leafy growth at the expense of the flowers you are after. A neutral pH around 5.6 to 7.5 is fine. The one thing it will not tolerate is soggy soil, so make sure water drains away.
Water young plants steadily until they establish, then ease off—mature chamomile is drought-tolerant and does well on about an inch of water per week, less in cool weather. Overwatering invites root and stem rot. Skip the fertilizer almost entirely; chamomile thrives on neglect, and feeding it generally means fewer, weaker blooms. If your soil is truly poor, a light compost topdressing in spring is all it needs.
Care Through the Season
The main ongoing job is picking, which doubles as deadheading and keeps flowers coming (covered below). German chamomile can flop as it grows tall and top-heavy; a few twiggy supports or simply planting it densely so stems lean on each other keeps it upright. Roman chamomile occasionally benefits from a light shearing after its main flush to tidy the mat and encourage rebloom.
Chamomile is famously trouble-free with pests. It is sometimes called the “plant’s physician” for its reputation of helping neighbors nearby, and aphids or thrips occasionally visit but rarely cause real damage—a blast of water or insecticidal soap handles them. The realistic risks are fungal: powdery mildew and rot in crowded, humid, or overwatered conditions. Space for airflow, water at the base, and you will rarely see a problem. If you are integrating it into a lawn-alternative planting, our Outdoor Living guides cover groundcover establishment.
Growing Chamomile in Containers
Both types grow well in pots, which is handy if you want chamomile within arm’s reach of the kettle or you garden on a balcony. German chamomile, being tall and branching, suits a deeper container at least 8 to 12 inches across so its roots have room and the top-heavy stems stay stable. Roman chamomile, low and spreading, looks lovely cascading over the edge of a shallow bowl or trough. Use a well-draining potting mix—chamomile hates wet feet, and a pot magnifies that risk—and add a little extra grit or perlite if your mix holds water.
Sow seed on the surface as you would in the ground, keep the pot in full sun, and water when the top inch dries; containers need more frequent watering than beds but chamomile still prefers to run on the dry side. Skip fertilizer—a container of chamomile flowers better lean than rich. The bonus of pot culture is total control over its reseeding: in the garden German chamomile scatters everywhere, but in a pot you simply collect or discard the spent flowers, and the patch stays exactly where you put it.
Harvesting Chamomile Flowers
Harvest the flower heads, not the foliage. The ideal moment is when the white petals are still flat or have just begun to bend back from the raised golden center—this is when the essential oils and that signature apple-honey aroma are strongest. Pick on a dry, sunny morning after the dew has lifted. The easiest method is to cup your hand under a cluster and pinch or comb the heads off with your fingers; some gardeners use a small berry-rake-style comb to speed it up.
Pick every two or three days at peak bloom. Constant harvesting acts as deadheading and pushes the plant to keep producing flowers for weeks rather than rushing to set seed. To dry them, spread the heads in a single layer on a screen or tray in a warm, dark, well-ventilated spot for one to two weeks until they are papery and crisp, then store in an airtight jar away from light. It takes a surprising volume of flowers to fill a jar, which is exactly why German chamomile’s heavy yield is worth the space. Toward the end of the season, leave a final round of flowers unpicked so they drop seed and your chamomile patch returns next year.
Frequently Asked Questions
What’s the difference between German and Roman chamomile?
German chamomile is a tall reseeding annual that produces abundant flowers, best for tea. Roman chamomile is a low-growing perennial that forms a fragrant mat, often used as a groundcover. Both have the same apple-scented daisy flowers, but German yields far more of them.
Does chamomile come back every year?
Roman chamomile is a true perennial in zones 4–9 and returns from its roots. German chamomile is an annual, but it self-seeds so freely that a patch effectively comes back on its own—just leave some flowers unpicked at season’s end to drop seed.
When should I pick chamomile flowers?
Harvest when the white petals are flat or just starting to bend back from the golden center, which is when the oils are most potent. Pick on a dry morning after the dew dries, and harvest every few days to keep new blooms coming all season.
Can chamomile grow in shade?
It flowers best in full sun, but it tolerates light or afternoon shade, which is actually helpful in hot climates where full sun can cause it to bolt and fade. In deep shade it grows leggy and blooms poorly, so aim for at least a few hours of direct sun.
Why is my chamomile not flowering well?
The most common cause is overly rich soil or too much fertilizer, which drives leafy growth instead of blooms. Chamomile flowers best in lean, well-drained soil with full sun. Too little light or overwatering will also cut down flowering.
