Re: germinating koreana?

I've heard that some irises (such as cristata) require 2 winters to 
germinate.  I would venture to say that if your koreana seeds do not 
germinate this spring, they're probably not ever going to.  (This would be 
their 3rd winter.)

I'm not sure what the scientific community thinks, but I suspect cristata 
is closely related to koreana and odaesanensis (in fact I wonder if 
odaesanensis is just some alba form of koreana or minutoaurea), so my guess 
is that koreana may have similar germination requirements to 
cristata.  Just my humble, amateur opinion!  I've not tried growing either 
one from seed myself.
