I came back from my holiday break to find this one in full bloom. Spike took 7 weeks to mature. 14 deeply purple 1" flowers. Flowers have a very pleasant floral scent, which peaks in the morning, and disappears by night.
I grow it mounted on wood branches with live moss, and water daily. I was worried about losing the flowers during the 2.5 weeks I was away, during which time it went without any watering. However I don't think the orchid suffered at all from the dry spell.
