About
This medium to large-sized, evergreen, epiphytic orchid producing a clump of oval to elliptic pseudobulbs. In summer, flowering stems emerge from the base of the maturing pseudobulbs. Each pseudobulb is covered in thin sheaths and carries one, 25-30cm long and 3-4cm wide, leathery, elliptic leaf. Each 10-15cm long stem carries single, up to 20cm large, attractive, scented flower. Petals and sepals are thin, curved, forward-facing, bright yellow, white at the base with dark brown markings.

Care notes
CultivationGrow in an open, free-draining, medium-grade, bark-based orchid mix with addition of perlite, sphagnum moss or coir. Requires day temperatures around 18-20°C and 14-16°C at night. Provide good light levels, but avoid direct sunlight. Water plants thoroughly when compost is almost dry, allow to drain and use orchid fertiliser regularly during growing season. See also indoor orchid cultivation
PruningNo pruning required
PropagationPropagation by seed is only possible in a controlled laboratory environment. Mature plants may be divided in early or mid spring, when the plant overgrows its container. Each division should have at least 3-4 healthy, older pseudobulbs with a sufficient amount of stored energy and water, to support new growth and reduce stress after repotting
Pest resistanceMay be susceptible to aphids, glasshouse red spider mite, scale insects and mealybugs
Disease resistanceGenerally disease-free. Poor air movement and soggy potting mix may cause risk of bacterial infections
