Yes, I've grown them... they're not especially easy to grow, you've got a good challenge on your hands if you find one. Make sure that you give it pure water and keep it wet all the time. Here's one that I bloomed...
This one is
Disa uniflora, although they frequently bloom with two flowers. I'm not selling them anymore, but I'm sure you'll be able to find someone. They need cool temps, and pure water... otherwise, they're not too tough.
