You got such a lovely plant! I just got mine, which is smaller than yours, and it has one flower in bloom. It's upside-down just like yours (is that a habit of this species), and not only that, but the back of the lip is also facing outwards. Maybe my plant is just wacky, lol.
Thanks for sharing the pics and the cultural info. I just got mine a few days ago and it's good to find out more info about it. I hope I can keep mine alive!
Also, I never heard of growing them in jars before. That is very interesting. Mine is in a 2" pot and I just happen to have clay pellets, moss, and a small glass bowl in handy.
