@jnduclos, while it has some similarities to
Daylily (Hemerocallis 'Moonlit Masquerade'), I don't think this dayily is that cultivar. While Moonlit Masquerade shows some eye markings on the sepals on just a few images, Susan's blooms show a much larger flared out eye pattern on the sepals.
There are many that have this look, probably many coming from MM breeding, and unless she gets clear confirmation from the seller or grows MM right next to this plant to make a comparison, one may never know the exact correct ID.
