Coneflower starting to open - a mystery as to it's variety

Diane took this picture today of a new coneflower she saw just starting to open.  She said this is not one she has photographed before and that this flower is not ill or have anything on it, that this is the color it is.  Very unusual looking, even I don't know which variety name this could be.  If you click on the photo, you can get a better view of this one.
