Corsican Heron's Bill (Corsican Stork's Bill) care

Light

Aim for at least 4-6 hours of direct sun on the leaves. Requires at least 6 hours of direct sun daily; inadequate light leads to lax, non-flowering growth and increased susceptibility to rot. If your only bright window faces south, that's perfect for corsican heron's bill — same window any aroid would fry on.

Watering

Watering corsican heron's bill: low — allow soil to dry between waterings. 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. Water sparingly once established; reduce to minimal irrigation in winter when the plant is semi-dormant, as wet winter roots are the chief killer.

Soil and pot

Corsican Heron's Bill grows best in well-drained gritty or sandy loam, alkaline to neutral. Add horticultural grit generously at planting; a raised bed or alpine trough with a grit mulch around the crown keeps moisture away from the stem base. 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

Corsican Heron's Bill sits happiest at around Low — 30–50% humidity and -10 to 25°C (14 to 77°F). Tolerates the dry, breezy conditions of Mediterranean coastal hillsides; high ambient humidity combined with poor drainage accelerates crown rot. 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 corsican heron's bill sparingly. Apply a low-nitrogen, high-potassium fertiliser (such as tomato feed) once in spring; avoid rich feeding, which promotes soft growth prone to rot. 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 corsican heron's bill in the Growli community. Each is annotated with the most common cause so you know where to start.

• Crown rot in wet winters — The most common cause of plant loss; ensure perfectly sharp drainage and apply a grit collar around the crown; consider an open cloche in prolonged wet spells.
• Vine weevil — Larvae eat roots undetected until plants collapse; use nematode biocontrol (Steinernema kraussei) in autumn and avoid mulching with organic material near the crown.

Propagation

Sow seed in autumn in a cold frame, or take basal softwood cuttings in late spring; division in spring is also possible on established clumps. 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

Corsican Heron's Bill is mildly toxic to pets. Erodium corsicum is not listed on the ASPCA Toxic and Non-Toxic Plant database. The closely related Erodium cicutarium is widely regarded as non-toxic to pets, but because specific ASPCA confirmation for ornamental Erodium species is absent, a mildly-toxic precautionary classification is used. No known severe toxic principles; keep away from pets as a precaution. 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.
