Anthurium andraeanum 'Florida' (Florida anthurium) care

Light

Bright but filtered. Anthurium andraeanum 'Florida' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright, indirect light keeps it flowering steadily; an east-facing window or a spot back from brighter glass is ideal. Direct sun scorches the spathes and leaves, and low light halts blooms. 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 andraeanum 'florida': when the top 2-3 cm of mix is dry, roughly every 5-7 days in growth. 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 thoroughly, let it drain fully, then allow the surface to dry before the next watering. The thick roots rot if kept wet, so empty saucers and reduce watering through winter.

Soil and pot

Anthurium andraeanum 'Florida' grows best in coarse, free-draining aroid mix. Combine orchid bark, perlite and coco coir or peat with charcoal for an open, well-aerated root zone. Heavy potting soil retains too much moisture and risks root rot. 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 'Florida' sits happiest at around 60-80% humidity and 18-29°C (65-84°F). High humidity keeps leaf tips healthy and prolongs spathe life. Use a humidifier, pebble tray or plant grouping to lift humidity in dry 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 'florida' sparingly. Feed every 4-6 weeks in spring and summer with a half-strength balanced fertiliser, or a high-phosphorus bloom feed for more spathes. Reduce feeding in autumn and winter and flush the pot occasionally to prevent salt build-up. 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 'florida' in the Growli community. Each is annotated with the most common cause so you know where to start.

• Sparse flowering — Too little light or over-feeding with nitrogen; increase indirect light and switch to a phosphorus-rich bloom feed.
• Brown leaf tips and edges — Low humidity or hard-water salts; raise humidity and use filtered or rainwater, flushing the pot periodically.
• Yellow lower leaves — Usually overwatering and poor drainage; let the mix dry more and ensure the pot drains freely.
• Root rot — Soggy media kills the roots; repot into airy mix, trim soft roots and allow the soil to dry between waterings.

Propagation

Divide established clumps at repotting, keeping roots on each section, or root stem cuttings with a node and aerial root. Grow on in fresh aroid mix kept warm and humid until established. 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 'Florida' is toxic to pets. ASPCA lists Anthurium (flamingo flower) as toxic to cats and dogs. The insoluble calcium oxalate crystals cause oral pain, heavy drooling, mouth swelling, vomiting and difficulty swallowing if chewed. Keep out of reach of pets and children. 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.
