Well, actually the rose is "Marlowe Soft Orange", whose blooms are normally something like those of 'Talisman' or 'Sutter's Gold' or 'Royal Sunset'. But today I noticed this oddball bloom, on just one side-shoot of a branch (other side-shoots are normally colored on the branch). First time for this rose in the dozen or more years I've had it and not only are the petals pink, their reverses are pale yellow instead of gold and it has at least double the number of petals, compared to a regular bloom. I had to double-check that the young 'Irene Bonnet' on the other side of the arch hadn't managed to sneak a cane over there already. Always fun!
