Ideal temperature for wisteria floribunda 'multijuga'
Temperature kills fewer wisteria floribunda 'multijuga' plants than you'd think. What kills them is the micro-climate within a normal-temperature room — a leaf pressed against single-glazed winter glass, the hot dry updraft directly above a radiator, the cold blast from an AC vent. The thermostat reading at -20 to 30°C (-4 to 86°F) is fine; the spot you put the plant in matters more. Below roughly -20°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Wisteria floribunda 'Multijuga' is comparatively hardy (USDA 5-9 (outdoor garden climber), RHS H6 (hardy throughout most of the UK)). 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 wisteria floribunda 'multijuga'
Wisteria floribunda 'Multijuga' sits happiest at around Outdoor ambient relative humidity. A hardy outdoor climber needing no humidity management. Standard temperate garden conditions and good air movement around the canopy keep it healthy. 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.

How cold can wisteria floribunda 'multijuga' tolerate?
Wisteria floribunda 'Multijuga' starts to suffer below roughly -20°C. It tolerates a cold dormant period within USDA 5-9 (outdoor garden climber), but a wet cold root zone is more dangerous than cold air.
