Ideal temperature for nelumbo 'baby doll'
Aim for 21-30°C (70-86°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 21°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Nelumbo 'Baby Doll' is comparatively hardy (USDA 4-10 (hardy if rhizome stays below the freeze line), 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 nelumbo 'baby doll'
Nelumbo 'Baby Doll' sits happiest at around Ambient (aquatic) relative humidity. Humidity is irrelevant for this flooded-root dwarf; the foliage handles any outdoor air while the roots stay underwater. 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.
