Ideal temperature for geranium × oxonianum 'wargrave pink'
Temperature kills fewer geranium × oxonianum 'wargrave pink' 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 -29 to 30°C (-20 to 86°F) is fine; the spot you put the plant in matters more. Below roughly -29°C growth pauses; cold beyond that pushes it into dormancy rather than killing it outright.
Cold tolerance & winter care
Geranium × oxonianum 'Wargrave Pink' 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 geranium × oxonianum 'wargrave pink'
Geranium × oxonianum 'Wargrave Pink' sits happiest at around Low to moderate, ambient outdoor relative humidity. A hardy, semi-evergreen border perennial with no humidity needs. Good airflow helps limit powdery mildew, to which the oxonianum group can be prone in dry, crowded conditions. 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.
Geranium × oxonianum 'Wargrave Pink' temperature & humidity — frequently asked questions
What temperature is best for geranium × oxonianum 'wargrave pink'?
Geranium × oxonianum 'Wargrave Pink' grows best between -29 to 30°C (-20 to 86°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 geranium × oxonianum 'wargrave pink' tolerate?
Geranium × oxonianum 'Wargrave Pink' starts to suffer below roughly -29°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 geranium × oxonianum 'wargrave pink' need?
Geranium × oxonianum 'Wargrave Pink' prefers about Low to moderate, ambient outdoor relative humidity. A hardy, semi-evergreen border perennial with no humidity needs. Good airflow helps limit powdery mildew, to which the oxonianum group can be prone in dry, crowded conditions.
How do I raise humidity for geranium × oxonianum 'wargrave pink'?
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.
Can geranium × oxonianum 'wargrave pink' live outside?
Geranium × oxonianum 'Wargrave Pink' 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.
