Okay, now I'm really confused. The photo of Kamata Nishiki on the Heartland peony website looks EXACTLY like mine, right down to the dark purple flares. Does Kamata Nishiki have flares?
I can't the URL to work see peonies.org

Here is your link to the main page. I believe that Kamata Nishiki has more of a reddish tone than the picture but different monitors will show pictures differently.

When you post a message to link to a site paste the link in the box below message that states Optional Link URL.

I say that and my link will probably not work.
