Thanks! Yeah, I'll post more flower pics and a whole plant pic once all are open. The second flower just started opening yesterday, so it shouldn't be long now.
I'll double check the label on Friday, but I don't remember this one being from a specific named line. As I recall, the tag just said either "P. lowii x sib." or "P. lowii x self." Can't remember offhand. I got it from Hausermann's about 2 years ago.
