I tried to get one from a place called Crystal Star Orchids in Ontario, Canada. Here is the link to his website:
Crystal Star Orchids
It was on their list of available plants at the time. What he does is accumulate orders and then when he has a large enough order, he imports from Taiwan and other places. I didn't get mine because he didn't have enough orders, but was told they might have some in the spring. If he imports I would think he might also export to the U.S. So anyone interested enough to pursue getting an Enobi Purple Splash might want to try requesting one from him. Maybe if there are enough orders, he can get a bunch in. I have read from someone in Taiwan, that they are all over there and not uncommon at all.
