Neat, I hope it thrives for you Kate. I tried growing Bletillas from bulbs and although they made leaves, the first summer did them in. I never saw a flower, and the leaves petered out.
Trouble with terrestrials is you can't see as easily what happened to them. On the epiphytes you can see insect damage, fungal infection, cold damage etc. Sometimes takes a magnifying glass, but . . . at least most of the plant is visible.
I've had great success with Spathoglottis, though. They're often for sale at Lowe's in large pots, in bloom. I have several colors and once they start blooming, they seem to just go on and on.
