Ideal temperature for narcissus 'tete-a-tete'

Aim for Needs winter chilling below 9°C; grows at 5-18°C (Needs winter chilling below 48°F; grows at 40-65°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 9°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.

Cold tolerance & winter care

Narcissus 'Tete-a-Tete' is comparatively hardy (USDA 3-9, RHS H6). 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 narcissus 'tete-a-tete'

Narcissus 'Tete-a-Tete' sits happiest at around Ambient outdoor relative humidity. An outdoor and container bulb with no special humidity needs. When forced indoors, keep it in a cool, bright spot to prolong the short-lived flowers. 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.
