Neanthe Bella Palm and the RHS hardiness rating
Neanthe Bella 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 neanthe bella palm USDA hardiness guide.

Because neanthe bella 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.
