Ideal temperature for sardinian glory of the snow
Temperature kills fewer sardinian glory of the snow 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 -20 to 20°C (-4 to 68°F) is fine; the spot you put the plant in matters more. Below roughly -20°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Sardinian Glory of the Snow is comparatively hardy (USDA 3-8, RHS H6). 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 sardinian glory of the snow
Sardinian Glory of the Snow sits happiest at around Low to moderate relative humidity. Suited to cool, temperate outdoor conditions; no special humidity requirements — good airflow around foliage reduces the risk of botrytis in damp springs. 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.
Sardinian Glory of the Snow temperature & humidity — frequently asked questions
What temperature is best for sardinian glory of the snow?
Sardinian Glory of the Snow grows best between -20 to 20°C (-4 to 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 sardinian glory of the snow tolerate?
Sardinian Glory of the Snow starts to suffer below roughly -20°C. It tolerates a cold dormant period within USDA 3-8, but a wet cold root zone is more dangerous than cold air.
What humidity does sardinian glory of the snow need?
Sardinian Glory of the Snow prefers about Low to moderate relative humidity. Suited to cool, temperate outdoor conditions; no special humidity requirements — good airflow around foliage reduces the risk of botrytis in damp springs.
How do I raise humidity for sardinian glory of the snow?
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 sardinian glory of the snow live outside?
Sardinian Glory of the Snow is rated for USDA zone 3-8 and RHS hardiness H6. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
