I have this lily blooming in my bed where I have planted several Platinum Palette varieties. I got them as very young plants, so they've not yet all produced flowers. I live in Zone 5a, and the mystery daylily just bloomed for me on July 5.
I know that I have PP Salmon Sunrise in the bed. I know that I have PP Pink Lavender Appeal in that bed. This one looks nothing like those two - any ideas what it could be?

For comparison, PP Pink Lavender Appeal (one bloomed last year, I'm sure they are in there)
For comparison, PP Salmon Sunrise (one of these bloomed last year, I'm sure they are in there)
