Bucephalandra Brownie Miami and the RHS hardiness rating
Bucephalandra Brownie Miami is rated RHS H1a — heated glasshouse — tropical, meaning it withstands winter minimums of about above 15°C. In practice that means it cannot live outdoors in the UK at any time; a warm indoor room or heated glasshouse only. 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 bucephalandra brownie miami USDA hardiness guide.
