If you have a university with a horticulture program any where near, you might try there -- the undergraduate program in my department sells some pretty funky varieties (rose form, variegated, speckled, etc) every year. What are you looking for? If they've got what you want here, I'll ship you one if you send me your address.
I have no idea but it looks like you've already got a good answer. Thank goodness for the Internet right? Your blog background is cute.
