Ideal temperature for peperomia 'napoli nights' (dark form)
Temperature kills fewer peperomia 'napoli nights' (dark form) 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 18-27°C (65-80°F) 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
Peperomia 'Napoli Nights' (dark form) is frost-tender (USDA 10-12 (indoor in most US homes), RHS H1b). 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 peperomia 'napoli nights' (dark form)
Peperomia 'Napoli Nights' (dark form) sits happiest at around 40-60% relative humidity. Comfortable in average household humidity and low-maintenance. Moderate humidity suits it but misting is unnecessary. Avoid persistently damp, cold, stagnant air that encourages rot. 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.

Peperomia 'Napoli Nights' (dark form) 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 peperomia 'napoli nights' (dark form) tolerate?
