Care at a glance
Light
Bright but filtered. Anthurium Coriaceum burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Thrives in bright, indirect light and tolerates a little gentle morning sun. Its leathery leaves handle brighter conditions than thin-leaved anthuriums, but harsh direct afternoon sun still bleaches and scorches. Insufficient light produces small, floppy leaves and a stretched rosette. If you only have a south window, set the plant back 1.5 m or hang a sheer curtain — both knock the intensity down into the right range.
Watering
Watering anthurium coriaceum: when the top 3-4 cm of mix is dry, roughly every 5-8 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. Keep the mix evenly moist but never waterlogged; water thoroughly, then let the surface dry slightly before the next round. The robust roots like oxygen, so empty any saucer promptly. Ease off in winter when growth slows and the plant uses less water.
Soil and pot
Anthurium Coriaceum grows best in chunky, well-draining aroid mix. Blend orchid bark, perlite, coco chips and some quality potting soil or worm castings for nutrients. As a semi-epiphyte it needs an airy, fast-draining medium that holds light moisture without compacting. Aim for slightly acidic pH and repot every couple of years as the plant fills out. 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
Anthurium Coriaceum sits happiest at around 60-80% humidity and 18-29°C (64-84°F). Prefers moderately high to high humidity but is more forgiving than velvet species. It can adapt to typical bright bathroom or well-humidified room levels around 60%; higher humidity yields larger, more pristine leaves. Provide airflow to avoid fungal leaf spots. If you keep the room above 18 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 anthurium coriaceum sparingly. Feed every 2-4 weeks through spring and summer with a balanced, diluted liquid fertiliser at half strength, or use slow-release granules. This vigorous grower responds well to steady, light feeding; flush occasionally to prevent salt buildup and reduce feeding over winter. 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 anthurium coriaceum in the Growli community. Each is annotated with the most common cause so you know where to start.
- Brown leaf tips and edges — Low humidity or salt and mineral buildup from hard water. Increase humidity and water with rain or filtered water, flushing the mix.
- Yellowing lower leaves — Often overwatering or a mix that stays soggy. Check roots, improve drainage and let the surface dry between waterings.
- Pale, stretched leaves — Too little light. Move to a brighter spot with strong indirect light to restore size and firmness.
- Mealybugs or scale — Hide in leaf bases and crevices of the rosette. Inspect regularly and treat with horticultural soap or alcohol swabs.
Propagation
Easiest by division of the basal offsets or by separating rooted clumps when repotting, ensuring each piece has its own roots. Seed propagation from ripe berries works but is slow. Pot divisions into a chunky aroid mix and keep warm and humid until new roots establish. 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
Anthurium Coriaceum is toxic to pets. Anthurium is listed by the ASPCA as toxic to cats and dogs (and horses). The toxic principle is insoluble calcium oxalate crystals; ingestion causes oral and tongue irritation, intense burning, drooling, vomiting and difficulty swallowing. Keep this large plant where pets cannot chew the leaves. 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.
Anthurium Coriaceum care — frequently asked questions
What is the common name for Anthurium coriaceum?
Anthurium coriaceum is most commonly called Anthurium Coriaceum, but it is also known as Leathery Anthurium, Coriaceum Anthurium. The names refer to the same species, so care instructions for Anthurium Coriaceum apply identically to anything sold as Leathery Anthurium.
How much light does anthurium coriaceum need?
Anthurium Coriaceum grows best in bright indirect light (just back from a sunny window). Thrives in bright, indirect light and tolerates a little gentle morning sun. Its leathery leaves handle brighter conditions than thin-leaved anthuriums, but harsh direct afternoon sun still bleaches and scorches. Insufficient light produces small, floppy leaves and a stretched rosette.
How often should I water anthurium coriaceum?
Water anthurium coriaceum when the top 3-4 cm of mix is dry, roughly every 5-8 days. Keep the mix evenly moist but never waterlogged; water thoroughly, then let the surface dry slightly before the next round. The robust roots like oxygen, so empty any saucer promptly. Ease off in winter when growth slows and the plant uses less water. 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 anthurium coriaceum toxic to cats and dogs?
Anthurium Coriaceum is toxic to pets. Anthurium is listed by the ASPCA as toxic to cats and dogs (and horses). The toxic principle is insoluble calcium oxalate crystals; ingestion causes oral and tongue irritation, intense burning, drooling, vomiting and difficulty swallowing. Keep this large plant where pets cannot chew the leaves.
What USDA hardiness zone does anthurium coriaceum grow in?
Anthurium Coriaceum is rated for USDA zone 10-12 (indoor in most US homes) and RHS hardiness H1b. Outside that range, grow it as a container plant that overwinters indoors before the first hard frost.
