Ideal temperature for carrion flower (stapelia gigantea)
Temperature kills fewer carrion flower (stapelia gigantea) 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 16-27 C ideal; do not go below ~10 C (60-80 F ideal; do not go below ~50 F) is fine; the spot you put the plant in matters more. Below roughly 16°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Carrion Flower (Stapelia gigantea) is frost-tender (USDA USDA zones 9-11 (Missouri Botanical Garden lists 9-10); grown as an indoor or greenhouse plant elsewhere and overwintered above 10 C / 50 F., RHS undefined). 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 carrion flower (stapelia gigantea)
Carrion Flower (Stapelia gigantea) sits happiest at around 30-50% (average household) relative humidity. Prefers low to average humidity and dislikes damp, stagnant air. Normal indoor humidity is fine and no misting is needed; misting actually raises rot risk. Good airflow around the stems is more important than humidity. 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.
Carrion Flower (Stapelia gigantea) temperature & humidity — frequently asked questions
What temperature is best for carrion flower (stapelia gigantea)?
Carrion Flower (Stapelia gigantea) grows best between 16-27 C ideal; do not go below ~10 C (60-80 F ideal; do not go below ~50 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 carrion flower (stapelia gigantea) tolerate?
Carrion Flower (Stapelia gigantea) starts to suffer below roughly 16°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.
What humidity does carrion flower (stapelia gigantea) need?
Carrion Flower (Stapelia gigantea) prefers about 30-50% (average household) relative humidity. Prefers low to average humidity and dislikes damp, stagnant air. Normal indoor humidity is fine and no misting is needed; misting actually raises rot risk. Good airflow around the stems is more important than humidity.
How do I raise humidity for carrion flower (stapelia gigantea)?
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 carrion flower (stapelia gigantea) live outside?
Carrion Flower (Stapelia gigantea) is rated for USDA zone USDA zones 9-11 (Missouri Botanical Garden lists 9-10); grown as an indoor or greenhouse plant elsewhere and overwintered above 10 C / 50 F.. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
