Lovely flowers, unusual color. I am pretty sure they are not E. peacockii, though. According to my guide book, they're supposed to be pink and tubular and arranged in a shepherd's crook, something like this:
There are a couple of different plants which have been reduced to synonymy as E. peacockii (one used to be called E. subsessilis). But they have nearly identical flowers despite some differences in the rosette.
I have never seen Echeveria flowers that weren't tubular (closed up to the end) so I'm actually not sure your plant is not an intergeneric hybrid. I wish I could come up with something to help figure out the mystery. Maybe for now it would be best to move the image to the generic Echeveria page (again, not sure that's right). Please let me know what you think, Tiffany.
