Our favorite place to shop for day lilies is Oakes Daylilies (http://www.oakesdaylilies.com/) If you love perusing catalogs, they have two in print, not to mention their online catalog. Take a virtual tour and you won't be disappointed!
(My daughter will let me know)
I love going to my daughter's garden. It's constantly changing. She and her husband do a beautiful job of keeping it maintained.
