Sri Lanka. This species is found in wet, tropical rainforests, so keep the roots evenly moist at all times and keep them warm. We use sphagnum moss in the root area and we don't give them a drying out period. Flowers are attractively multi-shades of pink, hanging from their long psuedobulbs, which are approximately 2 feet long. Flowers are long lasting! Growing now in 2" pots.
