That looks like a very nice double Joe. There doesn't appear to be cristation on the petals in the image only cresting on the extra segments. Do you have an image showing cristation on the petals? Sculpted and Double are two different Forms of daylilies. Sculpted cristate forms are single flowers, the cristation is on the petals of the second floral whorl. A Double form is a double flower with extra whorls of segments or petaloid stamens To be both a Sculpted cristate form and a Double form the flower would need cristation on the petals of the second whorl and also have extra floral whorls and/or petaloid stamens.
Chris, I don't have a blog or follow one on hardiness of certain daylilies. A lot is simply trial and error. This forum is a great resource to ask hardiness questions as well. The members are always willing to give their thoughts on a cultivar, good or bad. You can check the Daylily of the Day threads too. If a plant has been featured as a DotD it will appear in the upper right corner of that plants page in the database. We also have a quick link here in the forum on the right side in the Welcome to the Dayliles Forum box. There you will see some links listed. One is Daylily of the Day Archive.
Good luck convincing your wife into letting you dig up more lawn! Once she sees all your pretty seedlings it shouldn't be to hard. Plus it's a wonderful way to spend time your little one, what a cutie.
