Anthurium andraeanum 'Acropolis' (Acropolis anthurium) care

Light

Anthurium andraeanum 'Acropolis' is what florists mean by "bright spot, no direct sun" — close enough to a south or east window to feel the brightness, with a sheer curtain or a few feet of distance keeping the sun off the leaves. Bright, indirect light sustains the long flowering display; near an east window or sheer-filtered south light is ideal. White spathes scorch and discolour in direct sun, while low light stops bloom production. A phone lux-meter at the leaf surface should read 1,500-3,000 lux at noon.

Watering

Water anthurium andraeanum 'acropolis' when the top 2-3 cm of mix is dry, roughly every 5-7 days in growth. The actual day count varies with pot size, light, and season — the finger test (or lifting the pot to feel its weight) is more reliable than a fixed calendar. Empty any drainage saucer afterwards so the pot isn't sitting in water. Water deeply, let excess drain, and allow the surface to dry before watering again. Consistent light moisture suits it, but standing water rots the roots; reduce frequency in winter.

Soil and pot

Anthurium andraeanum 'Acropolis' grows best in coarse, free-draining aroid mix. Blend orchid bark, perlite and coco coir or peat with a handful of charcoal for an airy, well-drained root zone. Avoid heavy, water-retentive potting soil that suffocates the thick roots. 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 andraeanum 'Acropolis' sits happiest at around 60-80% humidity and 18-29°C (65-84°F). High humidity keeps the white spathes pristine and prevents leaf-tip browning. Use a humidifier or pebble tray in centrally heated or air-conditioned rooms. 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 andraeanum 'acropolis' sparingly. Apply a balanced houseplant feed at half strength every 4-6 weeks through spring and summer, or a bloom-boosting high-phosphorus formula to keep spathes coming. Pause feeding in the colder months and flush periodically to avoid salt accumulation. 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 andraeanum 'acropolis' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Spathes turning green — Some greening is natural ageing, but premature greening points to too little light or excess nitrogen; brighten the spot and switch to a phosphorus-rich feed.
• Brown leaf tips — Low humidity or mineral build-up in tap water; raise humidity and water with filtered or rainwater.
• Root rot and wilting — Caused by waterlogged mix; repot into airy media, trim mushy roots and let the soil dry between waterings.
• Sparse flowering — Insufficient light is the usual cause indoors; move closer to a bright, indirectly lit window.

Propagation

Divide mature clumps at repotting, keeping roots on each section, or root stem cuttings that include a node and aerial root. Grow on in fresh aroid mix kept warm and humid until new growth appears. 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 andraeanum 'Acropolis' is toxic to pets. ASPCA lists Anthurium (flamingo flower) as toxic to cats and dogs due to insoluble calcium oxalate crystals. Chewing or biting any part causes oral pain, profuse drooling, swelling, vomiting and trouble swallowing. Site it away from curious pets. 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.
