Looks like it could be to me. Some times the patten is different ( I have several roses with it). You do not have to get rid of the plant if it has mosaic virus unless it affects its performance and you aren’t happy with it. It won’t infect other plants and as far as I can tell most of the time my roses perform great and I just ignore the funky leaves.

Yes, that probably is RMV but if this is the first time you've seen symptoms in 12 years I certainly wouldn't be at all concerned about it. Have you had some unusual weather that may have stressed it in the past few months? Or some other condition that might have been hard on the rose? That's usually when you'll see symptoms, when a rose is stressed. Otherwise the rose will preform perfectly normal for many years. And I'll bet you'd be really hard pressed to find any Peace rose that isn't virused. During the period when that rose was introduce most all the roses were sold already virused from the rootstock they were grafted to.

Some of the more common rose viruses exhibit temperature dependent symptoms. This is interpreted to indicate that the rose immune system against that virus is more effective at high temperatures than at lower temperatures. If your virus exhibits that type of behavior, you probably are safe (in zone 9) in not removing the plant as for most (or all) of the flowering season the virus will be mainly in the roots and not in the pollen where it could be spread by insects to your other roses. However, if your roses are planted close together, the virus can be transferred by root to root grafting.

Thank you everyone, I was close to panic, I feel much better now. Although maybe it is time for a new Peace rose anyways. I may try to find an own root version if possible to replace it.
