Stolonifera Palm and the RHS hardiness rating
Stolonifera Palm is rated RHS H1b — heated glasshouse — subtropical, meaning it withstands winter minimums of about 10 to 15°C. In practice that means it indoors over winter; can summer outdoors once nights are reliably mild. 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 stolonifera palm USDA hardiness guide.
Does UK region change it?
Because stolonifera palm 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 stolonifera palm in the UK
Overwintering stolonifera palm 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.

Can stolonifera palm stay outside over winter in the UK?
No. Stolonifera Palm is frost-tender — a UK frost will kill it. Bring it indoors or into a frost-free greenhouse before the first autumn frost and return it outside only after the last spring frost.
What does RHS H1b mean?
RHS hardiness ratings run H1a (needs a heated glasshouse) to H7 (survives below -20°C). Stolonifera Palm's rating, H1b, means heated glasshouse — subtropical — it tolerates winter minimums of about 10 to 15°C. The rating is an absolute minimum, not an average.
How do I overwinter stolonifera palm in the UK?
