More about epipremnum amplissimum 'silver streak' in the UK
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. Epipremnum amplissimum 'Silver Streak' is frost-tender, so the radiator-warmed side of the house is right for it in winter — just not pressed against a cold pane or directly in the radiator updraft.
The actual numbers
Ideally epipremnum amplissimum 'silver streak' sits between 18-29°C. (That is 64-84°F in Fahrenheit.) Tolerates average household humidity but rewards higher levels with larger, more developed leaves. Aim for 50% or more; in very dry rooms leaf edges can brown. A pebble tray or nearby humidifier helps it climb and mature. Watch for the room dropping below about 18°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 epipremnum amplissimum 'silver streak' 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.
Epipremnum amplissimum 'Silver Streak' temperature in the UK — frequently asked questions
What temperature does epipremnum amplissimum 'silver streak' need in the UK?
Epipremnum amplissimum 'Silver Streak' prefers 18-29°C (64-84°F). 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 epipremnum amplissimum 'silver streak' survive a cold UK winter room?
Epipremnum amplissimum 'Silver Streak' is frost-tender (RHS H1b). Keep it well above freezing, ideally above 10°C overnight, which means the radiator-warmed side of the house rather than an unheated bedroom or conservatory.
Can epipremnum amplissimum 'silver streak' 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 epipremnum amplissimum 'silver streak' out?
Yes — UK living rooms typically run at around 25–35% relative humidity in winter. That is well below what most houseplants prefer. Epipremnum amplissimum 'Silver Streak' tolerates this better than the calathea-and-fern family, but a pebble tray or grouping plants still helps.
What temperature range does epipremnum amplissimum 'silver streak' actually like?
18-29°C is the comfortable band (64-84°F 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.
