Why is my rose bush all spotty?

I got this question from a client of mine. Her roses are amazing! However one bush has this discoloration on the leaves even though the rest of the plant and blooms appear just fine. She wanted to know what the problem is. This is Rose Mosaic Virus. This virus does not move from plant to plant and does not seem to affect the health of the plant, only the appearance. If it is disturbing to you, replace the plant with a new one.
