Wow, I looked that plant up out of curiosity, no wonder you're trying to find it. Very striking, I bet you miss having it. I looked around various places online, no luck. I have never seen it in any garden center I've been in and I like house plants. Maybe someone will still stop in and say they have but it pretty much looks like it's only the UK and it looked like Germany and Swiss and some other countries were advertising it also. Good luck with your search though. Welcome to the US and I hope you like growing other things here too.
