Anthurium andraeanum 'Roxanne' (Roxanne anthurium) care

Light

Bright but filtered. Anthurium andraeanum 'Roxanne' burns within days in unfiltered south-facing summer sun, and stops growing within months in deep shade. Bright indirect light drives steady flowering. Too little light and the salmon spathes stop forming; direct sun scorches leaves and bleaches the spathes. A spot near an east or filtered south/west window is ideal. 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 'roxanne': when the top 2-3 cm of mix is dry, roughly every 7-10 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 lightly moist but never soggy. Water thoroughly, let it drain, and empty the saucer. Allowing the surface to dry slightly between waterings prevents root rot, the most common killer of potted flamingo flowers.

Soil and pot

Anthurium andraeanum 'Roxanne' grows best in coarse, well-draining aroid/orchid blend. Use a chunky mix of orchid bark, perlite, coco coir or peat, and charcoal. It holds gentle moisture while staying airy, protecting the fleshy roots from waterlogging and supporting continuous bloom production. 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 'Roxanne' sits happiest at around 50-70% humidity and 18-27°C (65-80°F). Prefers moderate-to-high humidity for clean foliage and lasting spathes. It tolerates average room humidity better than the rare epiphytic species, but below 40% leaf tips brown; a pebble tray or humidifier helps. 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 'roxanne' sparingly. Feed every 4-6 weeks in spring and summer with a balanced or slightly higher-phosphorus water-soluble fertiliser at quarter to half strength to sustain blooming. Reduce in winter, and flush occasionally to prevent salt build-up that browns leaf tips. 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 'roxanne' in the Growli community. Each is annotated with the most common cause so you know where to start.

• No flowers — Most often too little light or too much nitrogen. Increase bright indirect light and use a higher-phosphorus feed.
• Browning leaf and spathe tips — Low humidity or fertiliser-salt build-up. Raise humidity, use low-mineral water, and flush the pot.
• Yellowing leaves — Overwatering and poor drainage. Let the surface dry between waterings and ensure the mix drains freely.
• Faded or sunburned spathes — Direct sun bleaches and scorches the salmon colour. Move to filtered, bright indirect light.

Propagation

Propagate by division: separate rooted offsets or split the clump at repotting, ensuring each piece has roots and a growing point. Pot divisions into a chunky aroid mix and keep 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 'Roxanne' is toxic to pets. Toxic to cats and dogs. Anthurium is ASPCA-listed as toxic; the leaves and colourful spathes contain insoluble calcium oxalate crystals. Ingestion causes oral pain, drooling, swelling of the mouth and throat, and vomiting. Keep this flowering plant away from 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.
