A large-sized, evergreen, tropical orchid with long, upright, cane-like stems (pseudobulbs), up to 130cm high. Bright green leaves are arranged along the cane nodes, stiff and up to 25cm long. The flowering stems measuring up to 25cm emerge from the upper nodes of mature pseudobulbs and carry 3 to 15 flowers. The flowers are waxy, long lasting approximately 7.5cm across. The sepals are white, petals are narrower, pointing upright and often spirally twisted. The lip is white with purple veined markings.

How to grow
Plants 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. Provide very bright light conditions and 80% humidity throughout the year. See indoor orchid cultivation
Propagation 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.
Suggested planting locations and garden types
- Conservatory and greenhouse
No 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.
