Ideal temperature for eschscholzia californica 'thai silk rose chiffon'
Aim for 10-25°C (50-77°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 10°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Eschscholzia californica 'Thai Silk Rose Chiffon' is comparatively hardy (USDA 6-10 (often a short-lived perennial in mild zones, grown as an annual), RHS H4). 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 eschscholzia californica 'thai silk rose chiffon'
Eschscholzia californica 'Thai Silk Rose Chiffon' sits happiest at around 30-50% relative humidity. Prefers dry, sunny conditions and dislikes prolonged damp, which encourages fungal problems. No added humidity is wanted; good airflow keeps plants 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.
Eschscholzia californica 'Thai Silk Rose Chiffon' temperature & humidity — frequently asked questions
What temperature is best for eschscholzia californica 'thai silk rose chiffon'?
Eschscholzia californica 'Thai Silk Rose Chiffon' grows best between 10-25°C (50-77°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 eschscholzia californica 'thai silk rose chiffon' tolerate?
Eschscholzia californica 'Thai Silk Rose Chiffon' starts to suffer below roughly 10°C. It tolerates a cold dormant period within USDA 6-10 (often a short-lived perennial in mild zones, grown as an annual), but a wet cold root zone is more dangerous than cold air.
What humidity does eschscholzia californica 'thai silk rose chiffon' need?

How do I raise humidity for eschscholzia californica 'thai silk rose chiffon'?
Group it with other plants, stand the pot on a tray of damp pebbles (kept above the waterline), or run a small humidifier in winter. Misting only helps for a few minutes, so it is the weakest option for a plant that genuinely needs more humidity.
