Ideal temperature for silberfeder silver feather grass

Temperature kills fewer silberfeder silver feather grass 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 -29 to 35°C (-20 to 95°F) is fine; the spot you put the plant in matters more. Below roughly -29°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.

Misting is the least effective — it raises humidity for minutes, not hours.
