Flame orchid is an imprecise common name, and a plant's roots, stems and botanical label should guide its care. Advice about creeping tubers should not be applied automatically to an epiphytic orchid with exposed roots.
Similar names can hide different plants
Flame orchid and flame lily are common names, not interchangeable botanical labels. An orchid such as a Renanthera and the climbing, tuberous Gloriosa superba have different structures and need different growing arrangements. A care instruction for a buried tuber cannot simply be transferred to an orchid with exposed roots.
Look at the whole plant
Start with the nursery label, then compare roots, stems and leaves. Do not identify a plant from a red or orange flower alone. If the label is missing, photograph the whole plant and its base before asking a reliable nursery or botanical collection for help.
Choose care after identification
Keep an established plant in its current stable conditions while resolving the name, unless there is an immediate drainage problem. Avoid cutting roots, dividing storage organs or changing the growing medium solely on the strength of a translated title. Once the botanical identity is clear, use a guide written for that plant and its local growing conditions.
