Ideal temperature for panicle hydrangea 'pinky winky'
Temperature kills fewer panicle hydrangea 'pinky winky' 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 -30 to 30°C (-22 to 86°F) is fine; the spot you put the plant in matters more. Below roughly -30°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Panicle Hydrangea 'Pinky Winky' is comparatively hardy (USDA 3-8, 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 panicle hydrangea 'pinky winky'
Panicle Hydrangea 'Pinky Winky' sits happiest at around 40-70% relative humidity. An outdoor shrub comfortable in ambient temperate humidity and tolerant of open, sunny positions. Steady soil moisture matters more than air humidity, but very hot, dry, exposed sites can still scorch leaf edges. 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.
