Ideal temperature for anthurium clarinervium (velvet cardboard anthurium)
Aim for 18-27°C (65-80°F) 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 clarinervium (Velvet Cardboard Anthurium) 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 clarinervium (velvet cardboard anthurium)
Anthurium clarinervium (Velvet Cardboard Anthurium) sits happiest at around 60-80% relative humidity. This is a high-humidity plant; below about 50% the leaf edges go brown and crispy and new leaves struggle to unfurl cleanly. A humidifier gives the most reliable results, with grouped plants or a pebble tray as backup. Misting offers only a brief, temporary lift and can encourage fungal spotting if leaves stay wet. 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 clarinervium (Velvet Cardboard Anthurium) temperature & humidity — frequently asked questions
What temperature is best for anthurium clarinervium (velvet cardboard anthurium)?
Anthurium clarinervium (Velvet Cardboard Anthurium) grows best between 18-27°C (65-80°F). 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 clarinervium (velvet cardboard anthurium) tolerate?
Anthurium clarinervium (Velvet Cardboard Anthurium) 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 clarinervium (velvet cardboard anthurium) need?
Anthurium clarinervium (Velvet Cardboard Anthurium) prefers about 60-80% relative humidity. This is a high-humidity plant; below about 50% the leaf edges go brown and crispy and new leaves struggle to unfurl cleanly. A humidifier gives the most reliable results, with grouped plants or a pebble tray as backup. Misting offers only a brief, temporary lift and can encourage fungal spotting if leaves stay wet.
How do I raise humidity for anthurium clarinervium (velvet cardboard anthurium)?
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 clarinervium (velvet cardboard anthurium) live outside?
Anthurium clarinervium (Velvet Cardboard Anthurium) 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.
