Ideal temperature for echeveria agavoides 'ebony'
Echeveria agavoides 'Ebony' is comfortable in any room a person is comfortable in, roughly 18-27°C (65-80°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 18°C the damage starts — soft blackened patches, translucent leaves, sometimes overnight.
Cold tolerance & winter care
Echeveria agavoides 'Ebony' is frost-tender (USDA 9a-11 (indoor in most US homes), RHS H2). 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 echeveria agavoides 'ebony'
Echeveria agavoides 'Ebony' sits happiest at around 30-50% relative humidity. Prefers dry indoor air and good airflow. Humid, stagnant conditions risk fungal leaf spots; the waxy leaves need no misting and resent water sitting on them. 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.
Echeveria agavoides 'Ebony' temperature & humidity — frequently asked questions
What temperature is best for echeveria agavoides 'ebony'?
Echeveria agavoides 'Ebony' 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 echeveria agavoides 'ebony' tolerate?
Echeveria agavoides 'Ebony' 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.
What humidity does echeveria agavoides 'ebony' need?
Echeveria agavoides 'Ebony' prefers about 30-50% relative humidity. Prefers dry indoor air and good airflow. Humid, stagnant conditions risk fungal leaf spots; the waxy leaves need no misting and resent water sitting on them.
How do I raise humidity for echeveria agavoides 'ebony'?
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 echeveria agavoides 'ebony' live outside?
Echeveria agavoides 'Ebony' is rated for USDA zone 9a-11 (indoor in most US homes) and RHS hardiness H2. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
