Ideal temperature for anthurium besseae aff. (dark velvet)
Anthurium besseae aff. (Dark Velvet) is comfortable in any room a person is comfortable in, roughly 18-27C (65-80F). 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
Anthurium besseae aff. (Dark Velvet) is frost-tender (USDA Not winter-hardy; grow indoors. Roughly USDA zone 11+ outdoors (tolerates no frost; protect below about 15C / 59F)., 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 anthurium besseae aff. (dark velvet)
Anthurium besseae aff. (Dark Velvet) sits happiest at around 60-80% relative humidity. High humidity is essential for this velvet-leaf species; aim for 70% or higher. It thrives in terrariums, cabinets or grow tents. Use a humidifier or pebble tray, and provide gentle air movement to prevent fungal spotting on the foliage. 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.
