Care at a glance
Light
Aim for at least 4-6 hours of direct sun on the leaves. Performs best in full sun, which gives upright, well-flowered spikes. It will grow in partial shade but becomes leggier and flowers less freely. If your only bright window faces south, that's perfect for agrimony — same window any aroid would fry on.
Watering
Watering agrimony: water to establish, then only in prolonged drought, roughly every 10-14 days. The number that matters isn't the day of the week — it's how dry the top 2-3 cm of the pot feels. A finger in the soil tells you more than a watering app. After every watering, tip the saucer. Drought-tolerant once rooted and suited to free-draining sites. Avoid persistently wet soil, though it copes with a wider moisture range than most Mediterranean herbs.
Soil and pot
Agrimony grows best in average to poor, well-drained, alkaline-leaning soil. Thrives on chalky, sandy or stony ground and ordinary garden soil. Prefers neutral to alkaline pH and good drainage; very rich soils give floppy growth. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.
Humidity and temperature
Agrimony sits happiest at around Ambient outdoor humidity and 10-25°C (50-77°F). An outdoor meadow perennial with no special humidity needs; it favours open, sunny, airy grassland conditions. If you keep the room above 10 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.
Fertilising
Feed agrimony sparingly. Needs no routine feeding and prefers lean soil. An occasional light spring mulch is ample; fertiliser encourages soft, sprawling growth at the expense of sturdy flower spikes. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.
Common problems
Below are the issues we see most often on agrimony in the Growli community. Each is annotated with the most common cause so you know where to start.
- Clinging burr seedheads — Hooked seeds catch on fur and clothing and spread the plant widely; cut back spent spikes before seed sets if you want to limit spread.
- Legginess in shade — Stems flop and flower poorly in low light; grow in full sun for sturdy, upright spikes.
- Powdery mildew — Dry, crowded plants can develop mildew on the foliage late in the season; thin and water at the base to improve airflow.
- Self-seeding — Sets seed freely in suitable sites; deadhead to keep it from naturalising beyond where you want it.
Propagation
Usually grown from seed sown in autumn or spring after cold exposure. Established clumps can be divided in spring or autumn to make more plants. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.
Toxicity to pets
Agrimony is mildly toxic to pets. Not individually listed by the ASPCA; treat with caution and verify with a vet. Agrimony is high in tannins, which can cause nausea, vomiting and diarrhoea if grazed in quantity. It is not confirmed as non-toxic by the ASPCA, so although risk is generally low, do not assume it is pet-safe. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).
Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
Agrimony care — frequently asked questions
What is the common name for Agrimonia eupatoria?
Agrimonia eupatoria is most commonly called Agrimony, but it is also known as agrimony, common agrimony, church steeples. The names refer to the same species, so care instructions for Agrimony apply identically to anything sold as church steeples.
How much light does agrimony need?
Agrimony grows best in direct sun (at least 4-6 hours). Performs best in full sun, which gives upright, well-flowered spikes. It will grow in partial shade but becomes leggier and flowers less freely.
How often should I water agrimony?
Water agrimony water to establish, then only in prolonged drought, roughly every 10-14 days. Drought-tolerant once rooted and suited to free-draining sites. Avoid persistently wet soil, though it copes with a wider moisture range than most Mediterranean herbs. The finger-test (or lifting the pot to feel its weight) beats a fixed weekly calendar because pot size, light, and season all change how fast the soil dries.
Is agrimony toxic to cats and dogs?
Agrimony is mildly toxic to pets. Not individually listed by the ASPCA; treat with caution and verify with a vet. Agrimony is high in tannins, which can cause nausea, vomiting and diarrhoea if grazed in quantity. It is not confirmed as non-toxic by the ASPCA, so although risk is generally low, do not assume it is pet-safe.
What USDA hardiness zone does agrimony grow in?
Agrimony is rated for USDA zone 3-8 (outdoor perennial) and RHS hardiness H6. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
