More about anthurium 'pterodactyl'
Ideal temperature for anthurium 'pterodactyl'
Aim for 18-26C (64-79F) on the thermostat and you've handled the easy part. The hard part is the half-metre around the plant: window glass that drops to near-freezing on a January night, a radiator pumping out hot dry air, a draught from an opened front door. Move the plant 30 cm and you've usually fixed the problem. Below roughly 18°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Anthurium 'Pterodactyl' is comparatively hardy (USDA undefined, RHS undefined). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for anthurium 'pterodactyl'
Anthurium 'Pterodactyl' sits happiest at around 60-80% relative humidity. Thrives at 60-80% humidity. It can adapt to average household humidity after an acclimation period, but struggles below about 50%, where leaf edges turn dry and crispy. A humidifier or pebble tray helps; grouping with other plants also raises local humidity. The usual low-humidity tell is crisp brown leaf tips and edges while the soil moisture is fine — a sign the air, not the watering, is the problem. If you need to raise it, the reliable methods are grouping plants together, standing the pot on a tray of damp pebbles (the pot above the waterline, never in it), or running a small humidifier in winter when indoor heating dries the air most. Misting is the least effective — it raises humidity for minutes, not hours.
Anthurium 'Pterodactyl' temperature & humidity — frequently asked questions
What temperature is best for anthurium 'pterodactyl'?
Anthurium 'Pterodactyl' grows best between 18-26C (64-79F). Keep it out of cold draughts, off freezing windowsills in winter, and away from the hot dry air directly above radiators — the extremes matter far more than the average room temperature.
How cold can anthurium 'pterodactyl' tolerate?
Anthurium 'Pterodactyl' starts to suffer below roughly 18°C. It tolerates a cold dormant period within USDA undefined, but a wet cold root zone is more dangerous than cold air.
What humidity does anthurium 'pterodactyl' need?
Anthurium 'Pterodactyl' prefers about 60-80% relative humidity. Thrives at 60-80% humidity. It can adapt to average household humidity after an acclimation period, but struggles below about 50%, where leaf edges turn dry and crispy. A humidifier or pebble tray helps; grouping with other plants also raises local humidity.
How do I raise humidity for anthurium 'pterodactyl'?
Group it with other plants, stand the pot on a tray of damp pebbles (kept above the waterline), or run a small humidifier in winter. Misting only helps for a few minutes, so it is the weakest option for a plant that genuinely needs more humidity.
Can anthurium 'pterodactyl' live outside?
Anthurium 'Pterodactyl' is rated for USDA zone undefined. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
