Ideal temperature for daylily 'chicago apache'
Daylily 'Chicago Apache' is comfortable in any room a person is comfortable in, roughly 5-32°C (41-90°F). The mistakes are micro-climates: a north-facing window on a frosty night, a south-facing windowsill in a summer heatwave, the standing draught between an opened kitchen door and the radiator behind it. Read the room around the plant, not the thermostat. Below roughly 5°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Daylily 'Chicago Apache' 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 daylily 'chicago apache'
Daylily 'Chicago Apache' sits happiest at around 40-60% relative humidity. Adapts well to average outdoor humidity. High humidity combined with poor air circulation can encourage fungal leaf-streak disease; space plants at least 45–60 cm apart to promote airflow. 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.
