if your dream daylily is white with neon greenish teeth, check out LACHLAN NICOLE AGIN at Maryott's. It's really a light yellow with brighter teeth, but it's a start. I've just become a fan of Linda Agin's daylilies, and Maryott's has a super collection. Expensive, but aren't they beautiful?
I don't think this link will get you to the right page, but if you search on Agin I think you'll find hers.
