More about ashanti blood

Ideal temperature for ashanti blood

Ashanti Blood is comfortable in any room a person is comfortable in, roughly 18–32 °C (64–90 °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

Ashanti Blood is frost-tender (USDA 10a–11b, 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 ashanti blood

Ashanti Blood sits happiest at around 60–80% relative humidity. A true tropical that demands high humidity to maintain lush foliage and vibrant bract colour. In dry indoor environments, place on pebble trays with water, group with other tropical plants, or use a humidifier. Misting foliage is beneficial if airflow is good to prevent 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.

Ashanti Blood temperature & humidity — frequently asked questions

What temperature is best for ashanti blood?

Ashanti Blood grows best between 18–32 °C (64–90 °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 ashanti blood tolerate?

Ashanti Blood 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 ashanti blood need?

Ashanti Blood prefers about 60–80% relative humidity. A true tropical that demands high humidity to maintain lush foliage and vibrant bract colour. In dry indoor environments, place on pebble trays with water, group with other tropical plants, or use a humidifier. Misting foliage is beneficial if airflow is good to prevent fungal issues.

How do I raise humidity for ashanti blood?

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 ashanti blood live outside?

Ashanti Blood is rated for USDA zone 10a–11b and RHS hardiness H1a. Outside that range it must come indoors before the first frost — treat any outdoor stint as a summer holiday, not a permanent home.
