Orchid Origins - Shane - does my flasking. I can highly recommend.
I have produced a few zygo hybrids - pods dehisce at around 6 months. I have never harvested 'green pod'.
Keep us informed about your bletilla/zygo cross. I doubt whether there is anything there ( but who knows ? ) and suspect that its a 'false pregnancy'. Pod shouldn't last past 3 months..........if it does, there may be hope.
Well I'm known as the Dr. Frankstein of crosses in my orchid society. I waiting for my seedling from my Vanda X Phalenopsis cross to grow, as well as my Leptotes X Prostecha cross. Someone has to cross line in hybridizing.
