Ideal temperature for white nancy dead nettle
White Nancy Dead Nettle is comfortable in any room a person is comfortable in, roughly -34°C to 29°C (-29°F to 84°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 -34°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
White Nancy Dead Nettle is comparatively hardy (USDA 3-8, RHS H7). Within that range it tolerates a cold dormant spell outdoors; outside it, grow it in a container you can move under cover or overwinter in a cool but frost-free spot. Hardiness assumes an established plant in well-drained soil — a wet, cold root zone kills far more plants than cold air alone.
Humidity for white nancy dead nettle
White Nancy Dead Nettle sits happiest at around Moderate; 40–60% RH relative humidity. Adapted to temperate outdoor humidity. Dislikes high heat combined with high humidity, which encourages fungal issues. Good air circulation around clumps is beneficial. 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.
