Hi Jen,
I believe it's likely a specific clone that is a coerulea they've used in breeding (just like many awarded clones of different plants have the same registered name), but don't take my word for it!
On a related note, could you link the import list here? I think I'm on their mailing list but I didn't get this one. I love nobilior too, and should have some really nice plants coming into bloom in a few years! When I love a species, I tend to get most of the color forms available and that is certainly the case for this one.
