Ideal temperature for angel's tears narcissus
Aim for −15°C to 18°C (5°F to 64°F) on the thermostat and you've handled the easy part. The hard part is the half-metre around the plant: window glass that drops to near-freezing on a January night, a radiator pumping out hot dry air, a draught from an opened front door. Move the plant 30 cm and you've usually fixed the problem. Below roughly 15°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Angel's Tears Narcissus is comparatively hardy (USDA 5-9, RHS H5). 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 angel's tears narcissus
Angel's Tears Narcissus sits happiest at around Low to moderate (30–55% RH) relative humidity. Adapted to exposed, wind-swept Iberian habitats with relatively low humidity. It does not require high humidity and is susceptible to fungal issues in persistently damp conditions. Good air circulation around the planting site 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.
Angel's Tears Narcissus temperature & humidity — frequently asked questions
What temperature is best for angel's tears narcissus?
Angel's Tears Narcissus grows best between −15°C to 18°C (5°F to 64°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 angel's tears narcissus tolerate?
Angel's Tears Narcissus starts to suffer below roughly 15°C. It tolerates a cold dormant period within USDA 5-9, but a wet cold root zone is more dangerous than cold air.
What humidity does angel's tears narcissus need?
Angel's Tears Narcissus prefers about Low to moderate (30–55% RH) relative humidity. Adapted to exposed, wind-swept Iberian habitats with relatively low humidity. It does not require high humidity and is susceptible to fungal issues in persistently damp conditions. Good air circulation around the planting site is beneficial.
How do I raise humidity for angel's tears narcissus?
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 angel's tears narcissus live outside?
Angel's Tears Narcissus is rated for USDA zone 5-9 and RHS hardiness H5. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
