Proliferous Pleurothallis and the RHS hardiness rating
Proliferous Pleurothallis is rated RHS H1c — warm temperate, meaning it withstands winter minimums of about 5 to 10°C. In practice that means it fine outdoors through most UK summers but must come in before the first frost. The RHS rating describes an absolute minimum temperature, not an average: a single hard frost below its band is what does the damage, so the question is always "what is the coldest night my garden gets?", not "what is a typical winter here?".
This follows the RHS plant hardiness rating system (H1a–H7), the UK standard. For the US growing-zone view, see the proliferous pleurothallis USDA hardiness guide.
Does UK region change it?
Because proliferous pleurothallis is frost-tender, UK region matters less than the simple rule: it does not stay outdoors over winter anywhere in the UK. Treat any time outside as a summer holiday — bring it back indoors once nights drop toward 10°C, well before the first frost, and acclimatise it over a week each way so the leaves do not shock.
Overwintering proliferous pleurothallis in the UK
Overwintering proliferous pleurothallis in the UK means bringing it in: a bright, frost-free room or a heated glasshouse, watered sparingly while growth slows. Do not leave it against cold glass or near an unheated porch. Move it back out only after the last spring frost has passed for your area.
