Ideal temperature for queen of the andes
Temperature kills fewer queen of the andes plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at 5-20°C (41-68°F) is fine; the spot you put the plant in matters more. Below roughly 5°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Queen of the Andes is comparatively hardy (USDA 9-11, RHS H3). 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 queen of the andes
Queen of the Andes sits happiest at around 20-50% relative humidity. Tolerates low ambient humidity well, reflecting its origin in arid montane environments. Average household humidity is adequate; no misting or pebble trays needed. 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.
Queen of the Andes temperature & humidity — frequently asked questions
What temperature is best for queen of the andes?
Queen of the Andes grows best between 5-20°C (41-68°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 queen of the andes tolerate?
Queen of the Andes starts to suffer below roughly 5°C. It tolerates a cold dormant period within USDA 9-11, but a wet cold root zone is more dangerous than cold air.
What humidity does queen of the andes need?
Queen of the Andes prefers about 20-50% relative humidity. Tolerates low ambient humidity well, reflecting its origin in arid montane environments. Average household humidity is adequate; no misting or pebble trays needed.
How do I raise humidity for queen of the andes?
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 queen of the andes live outside?
Queen of the Andes is rated for USDA zone 9-11 and RHS hardiness H3. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
