Ideal temperature for lipstick plant 'mona lisa'
Temperature kills fewer lipstick plant 'mona lisa' 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
Lipstick Plant 'Mona Lisa' 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 lipstick plant 'mona lisa'
Lipstick Plant 'Mona Lisa' sits happiest at around 50-60% relative humidity. Prefers above-average humidity. A pebble tray, nearby humidifier or a bright bathroom keeps the foliage glossy; very dry air causes leaf-tip browning and bud drop. 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.

What temperature is best for lipstick plant 'mona lisa'?
