Oddly, I've managed to find everything I've wanted, mostly. There are a couple of things that are eluding me.
I'm looking for Underneath the Ice, which is a full sibling of Pigment of Imagination. It has a few qualities that appeal to me more than its better known relative. So I thought I would ask here. Anyone have any insight?
Addition: Chicago Blue Eyes. Until today, I didn't know this existed. Unlike tet. Prairie Blue Eyes, this was bred from tetraploid parents, and has greater genetic stability. That being said, I wonder why it wasn't used for hybridizing more than it was.
