Not totally disappeared...just mostly.
There was some nasty storm last year - I don't remember exactly when - and Aaron lost power for several days. That was sadly the demise of all of the flasks of babies. They were close to replating size, too.
It was a neat experience flasking them for ourselves, and I encourage anyone interested to give it a try. But if it's a cross you really want to guarantee survives, have it flasked by a professional lab.
Sorry the story doesn't have a happy ending, but I'm happier for the experience. And that's really what orchid growing is all about.
