Well, I had one, a beautiful "Double Delight" which started out yellow, then changed to pink as the flower aged. Then the kangaroos got at it; then the feral deer. It reverted to a single dark red flower of the rootstock. Then, same again, aided and abetted by a couple of hares that could have been saddled they were so big. Sad to say, that was the end of my rose, it's now just a stick. Just waiting to see if there is any further attempts to re-grow. . .π
