The UK home, in plant terms
A typical UK home creates two opposite micro-problems at the same time. Radiator-driven heating spikes the air temperature and crashes humidity in the rooms where people actually sit; the older the housing stock the more likely a single-glazed window pane is sitting at near-freezing in January with a houseplant against it. Cold unheated bedrooms, north-facing rooms and conservatories without heating run far cooler than the thermostat suggests, and the British winter gives the lowest indoor daylight in any of Growli's markets. Philodendron 'Prince of Orange' tolerates a wider band, but the worst-case UK winter placement (a cold single-glazed pane plus a hot dry radiator below it) still stresses it through repeated drying and chilling.
The actual numbers
Ideally philodendron 'prince of orange' sits between 15-29C. (That is 60-85F in Fahrenheit.) As a tropical aroid it prefers moderate to high humidity (ideally 60-70%) but adapts to average home levels around 50%. Boost humidity with a humidifier or by grouping plants if leaf edges brown. Watch for the room dropping below about 15°C overnight — common in UK unheated bedrooms in January, and the point where growth stalls and leaves chill-mark.

Winter placement in a UK home
For philodendron 'prince of orange' through a UK winter, three placement rules clear up most problems: 1) keep it at least a hand's width back from the window pane on single-glazed or very cold double-glazed glass, especially overnight when curtains close behind the plant; 2) keep it out of the direct vertical updraft above a radiator — that column of hot dry air browns leaf tips even on tolerant species; 3) judge by the room you can actually feel, not the central thermostat — many UK rooms run several degrees below the hall reading in winter. Humidity drops to roughly 25–35% in a heated UK living room; a pebble tray, grouping with other plants, or a small humidifier puts that back to a level houseplants actually like.
Philodendron 'Prince of Orange' temperature in the UK — frequently asked questions
What temperature does philodendron 'prince of orange' need in the UK?
Philodendron 'Prince of Orange' prefers 15-29C (60-85F). The British issue is rarely the average — it is the extremes: a cold single-glazed window in January, the hot dry air directly above a radiator, or a north-facing unheated room that runs far cooler than the hall thermostat.
Will philodendron 'prince of orange' survive a cold UK winter room?
Philodendron 'Prince of Orange' tolerates a wider winter band — see its RHS rating undefined. Below about 15°C growth stalls; cold-wet roots, not cold air, are usually what kills it indoors.
Can philodendron 'prince of orange' go on a UK windowsill in winter?
On a single-glazed or very cold pane, no — overnight the leaves pressed against the glass can drop below the plant's comfort band, especially behind drawn curtains. A small gap (a hand's width back) or thicker thermal curtains in front of the plant fixes it, and modern double-glazing usually solves it outright.
Does UK radiator-driven heating dry philodendron 'prince of orange' out?
Yes — UK living rooms typically run at around 25–35% relative humidity in winter. That is well below what most houseplants prefer. Philodendron 'Prince of Orange' tolerates this better than the calathea-and-fern family, but a pebble tray or grouping plants still helps.
What temperature range does philodendron 'prince of orange' actually like?
15-29C is the comfortable band (60-85F in Fahrenheit for reference). That covers normal UK living-room temperatures all year; the work is making sure cold pockets (windowsills, unheated rooms) and hot pockets (radiator updrafts) do not push it outside that band.
