Is this one of those species that doesn't like to flower in a pot? I 
think I got my start from Jane more than five years ago probably, and 
although it has filled the pot with offsets, none of them have ever 
bloomed. Is it not supposed to grow in my climate? Because it doesn't 
seem to mind it at all since it goes dormant during our summers all on 
its own.
