Ideal temperature for many-flowered temple bells
Temperature kills fewer many-flowered temple bells 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 18–25°C (growing); 10–15°C (dormancy storage) (64–77°F (growing); 50–59°F (dormancy storage)) is fine; the spot you put the plant in matters more. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Many-Flowered Temple Bells is frost-tender (USDA 11–12, RHS H1a). It cannot survive a frost, so in most of the US and UK it lives indoors year-round or summers outside and comes back in well before the first autumn frost — once nights drop toward 10-12°C is the cue, not the first frost warning. Acclimate it over a week when moving between indoors and out so the leaves do not shock.
Humidity for many-flowered temple bells
Many-Flowered Temple Bells sits happiest at around 60–80% relative humidity. Requires high ambient humidity. Use a pebble tray filled with water or a humidifier. Never mist the hairy leaves — water contact causes unsightly spotting and promotes fungal issues. 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.
Many-Flowered Temple Bells temperature & humidity — frequently asked questions
What temperature is best for many-flowered temple bells?

How cold can many-flowered temple bells tolerate?
Many-Flowered Temple Bells starts to suffer below roughly 18°C. It is frost-tender and will be damaged or killed by a frost, so bring it indoors once nights fall toward 10-12°C.
