Masdevallias are best known for their showy flowers consisting of sepals fused into a tubelike structure. Their origins in cool, damp environments make them an excellent choice for cool or coastal climates. Most species and hybrids are compact enough so that they can be easily accommodated on windowsills or under lights. Masdevallias can be kept in light intensities up to 2,500 foot-candles if the growing area can be kept cool.
Plants grow well under standard fluorescent fixtures and can be summered outside in shade.
In the home, place in an east or shaded south window or under artificial lights. The plants will grow slowly and eventually expire if temperatures remain high for long periods. Cool evenings help reduce heat stress during the day. Good-quality water low in dissolved solids is imperative for success. The ideal range is 60 to 80 percent.
