I won this at an auction at my local orchid society a few years ago. I am currently growing under lights and didn't think I would get it to bloom until I built a new greenhouse, but behold a nearly 3ft spike and many flowers and buds!
The tag says Mcp. thomsoniana but when I do a reverse search, Mcp. brysiana comes up. It seems most thomsoniana I am finding have a deep purple color on the lip. Thoughts?
