About
This epiphytic, evergreen orchid hybrid; with long, cane-like, fleshy, green pseudobulbs. Four to six dark green, leathery leaves are alternately arranged on the upper half or near the top of each cane. Each lance-shaped leaf is 8-14cm long and 3cm wide. Upright, or semi-pendulous flowering stems up to 40cm long emerge from the axils of leaves on mature canes and bear 12-15 flowers opening in succession. Each bright, purple-pink flower is over 7cm across, with a darker centre.

Care notes
CultivationPlants are best grown in a pot in an epiphytic, medium grade, bark-based potting mix with added perlite, moss, or coir. As with many orchids, they grow best when the roots are slightly restricted. Therefore, avoid over-potting or frequent root disturbance. It is a warm-growing orchid and the temperatures should not drop below 16°C. It can be grown similarly to Moth Orchid (Phalaenopsis) but requires much brighter conditions. Provide indirect light and higher humidity by misting regularly in spring and summer, then move the plant to a bright, room in autumn and winter. Water approximately once per week, ensure that roots dry-out between the waterings, especially in winter. See indoor orchid cultivation
PruningNo pruning required. Remove spent flowers as necessary, but do not cut the whole cane unless completely shrivelled. Oldest canes may be removed as long as there are at least three, younger, thick, leaf-bearing canes on the plant.
PropagationPropagation by seed is only possible in controlled laboratory environment. Mature plants may be divided when the plant overgrows the pot. Sideshoots (keiki) may develop on older canes -remove and pot them into sphagnum moss when the new roots are at least 2cm long.
Pest resistanceMay be susceptible to scale insects, aphids, mealybugs and red spider mite.
Disease resistanceGenerally disease-free.
