I know mine are 'White Queen' as they were labeled, and I think yours look just like mine. I'm voting for yours being 'White Queen'. I haven't had them bleed the red into the white areas, but we have not had a lot of rain this summer either, so that may be the reason.
In your link, the picture of 'Florida Fantasy' really does look just like 'White Queen' and there is at least one leaf in that picture with the red bleeding into the white.
Does it really matter as long as you're not planning on propagating and selling them?
