Several species of this orchid, particularly Paphiopedilum callosum and P. sukhakulii, and some of the smaller hybrids will do well in a living room, preferably near a window that does not receive too much sunlight. Wherever slipper orchids are sited, they require plenty of humidity as well as good ventilation during the hotter months.
Paphiopedilums do not require a dormant Paphiopedilum season, but if the temperature drops in winter, the water supply must be decreased. The blooms of these popular orchids have a striking sepal, usually called the flag; the lip of the flower is called the “slipper” because its pouch-like shape resembles a house slipper. Many hybrids are available from specialist suppliers, and new ones are being added constantly.
