Rob, it looks like Brent and Becky's is only selling paperwhite types of Daffs and Amaryllis now, but they are 50% off and the paperwhite varieties (non hardy tazetta class varieties) are hardy in your zone. And while there are a lot of Daffs that perform better in colder zones, you're in luck! One of my favorite classes of Daffodils are the jonquillas, and those perform in zones 4-9. They make great long term perennials, increase well, and are typically fragrant. Some of my jonquillas will up for division next year, so I'm bound to have extras (I'll split the warm zone varieties up between you and Ann
)
There are also some doubles good for your zone, Erlicheer is a great one, and Bridal Crown, Sir Winston Churchill, Cheerfulness and Yellow Cheerfulness are also excellent. I think those are all double forms of tazetta hybrids, which are also good choices for warmer zones. 'Geranium' is one of my all time favorites, a fragrant tazetta.
