Care at a glance
Light
Aim for at least 4-6 hours of direct sun on the leaves. Requires full sun; will not thrive in shade, which encourages pale, weak growth with poor aromatic quality in the leaves. If your only bright window faces south, that's perfect for musk stork's bill — same window any aroid would fry on.
Watering
Watering musk stork's bill: water moderately during active growth; keep nearly dry in dormancy. 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. As a Mediterranean annual/biennial, it tolerates extended dry periods; overwatering is more likely to cause harm than underwatering, particularly in heavy soils.
Soil and pot
Musk Stork's Bill grows best in well-drained, sandy or loamy, neutral to alkaline. Grows in light (sandy) or medium (loamy) soils; prefers neutral to mildly alkaline pH and will struggle in acidic, waterlogged, or heavily compacted ground. 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
Musk Stork's Bill sits happiest at around Low to moderate (35–55%) humidity and -8 to 30°C (18 to 86°F). Tolerates a range of humidity but benefits from good air circulation; high humidity coupled with damp soil can trigger fungal issues at the base of the rosette. If you keep the room above 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 musk stork's bill sparingly. Generally unnecessary in fertile soils; in poor soils, apply a balanced granular fertiliser lightly at sowing or transplanting time. 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 musk stork's bill in the Growli community. Each is annotated with the most common cause so you know where to start.
- Powdery mildew on leaves — Can develop in warm, dry conditions with poor air circulation; improve ventilation and avoid wetting foliage; remove affected leaves promptly.
- Aggressive self-seeding — The corkscrew-tipped seeds self-bury readily and E. moschatum can become weedy in borders; deadhead before seed ripens to contain spread.
Propagation
Direct sow seed in situ in late summer (for overwintering rosettes) or in early spring; seeds germinate readily without stratification in warm soil. 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
Musk Stork's Bill is mildly toxic to pets. Erodium moschatum is not listed by the ASPCA as a toxic plant, and the Erodium genus has no documented toxic principles for cats or dogs. Although the young leaves are eaten by humans, no formal ASPCA 'non-toxic' confirmation exists for this species, warranting a mildly-toxic classification for pets as a precaution. Mild gastrointestinal upset is possible if animals consume foliage. 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.

How often should I water musk stork's bill?
Water musk stork's bill water moderately during active growth; keep nearly dry in dormancy. As a Mediterranean annual/biennial, it tolerates extended dry periods; overwatering is more likely to cause harm than underwatering, particularly in heavy soils. 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 musk stork's bill toxic to cats and dogs?
Musk Stork's Bill is mildly toxic to pets. Erodium moschatum is not listed by the ASPCA as a toxic plant, and the Erodium genus has no documented toxic principles for cats or dogs.
