Primula, Asiatic Primrose, Capitata Primrose 'Noverna Deep Blue'

I got three of these in full bloom in late September three years ago. I loved the color, form, and powdery foliage, and the fact that the...Read Morey stayed in bloom for weeks afterwards. As Todd Boland has pointed out elsewhere, (http://davesgarden.com/guides/pf/go/79922/#b)
they are short lived. Mine aren't blooming at all this year, and look like they won't make it through the winter. I was hoping to divide them, but they haven't produced anything to divide. They didn't reseed, either, so I'm lifting them, transplanting them into lighter soil, keeping fingers crossed.

They are really pretty, and unusual, so I'll probably look for a replacement.
