Well, this is an interesting one - Burgundy Ice is a sport originally from Iceberg and Pink Iceberg - its also sometimes commonly called the harlequin rose, because it can produce burgundy, pink, white, or streaked versions of the flowers when it feels like it. Not sure I'd be that thrilled with a plant that can't decide what colour its going to be, and the sellers don't tell you that, but its certainly a novelty. Doesn't mean all the flowers will now be pink either - you'll not know what you're going to get from one flower or one year to the next. Information from Country Life, 31st August, 2014.

Thanks for your reply I will wait and see what happens next.
