Lisa, Plant Delights is a great source. Heronswood Gardens (http://www.heronswood.com/) also offers a few named varieties. Darrell Apps, owner/operator of Woodside (daylily) Nursery in Bridgeton, New Jersey, used to list two named varieties that were bred in the Pacific Northwest, and were hardy for him. You may need to contact him personally regarding these - I don't believe they are listed in his online catalog. http://woodsidenursery.com/paradise/supplier/… I hope this helps some. Jamie
