Ideal temperature for symphyotrichum novi-belgii 'fellowship'
Temperature kills fewer symphyotrichum novi-belgii 'fellowship' 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 -34 to 27°C (-30 to 80°F) is fine; the spot you put the plant in matters more. Below roughly -34°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Symphyotrichum novi-belgii 'Fellowship' is comparatively hardy (USDA 4-8, RHS H7). 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 symphyotrichum novi-belgii 'fellowship'
Symphyotrichum novi-belgii 'Fellowship' sits happiest at around Ambient outdoor relative humidity. A hardy garden perennial with no specific humidity requirement, though airflow matters: crowded, stagnant plantings dramatically increase powdery mildew on this mildew-prone species. 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.
Symphyotrichum novi-belgii 'Fellowship' temperature & humidity — frequently asked questions
What temperature is best for symphyotrichum novi-belgii 'fellowship'?
Symphyotrichum novi-belgii 'Fellowship' grows best between -34 to 27°C (-30 to 80°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 symphyotrichum novi-belgii 'fellowship' tolerate?
Symphyotrichum novi-belgii 'Fellowship' starts to suffer below roughly -34°C. It tolerates a cold dormant period within USDA 4-8, but a wet cold root zone is more dangerous than cold air.
What humidity does symphyotrichum novi-belgii 'fellowship' need?
Symphyotrichum novi-belgii 'Fellowship' prefers about Ambient outdoor relative humidity. A hardy garden perennial with no specific humidity requirement, though airflow matters: crowded, stagnant plantings dramatically increase powdery mildew on this mildew-prone species.

Can symphyotrichum novi-belgii 'fellowship' live outside?
Symphyotrichum novi-belgii 'Fellowship' is rated for USDA zone 4-8 and RHS hardiness H7. Within that range it can stay outdoors; outside it, grow it in a moveable container and protect the roots from a wet, cold winter.
