I love my roses but I'm wondering if I may have to remove them. Can this be anything other than mosaic virus? 1st three photos are of one of my Don Juan climbers and the last photo is a different bush. Not pictured is a third bush also afflicted. I planted most from bare root and I have so loved watching them all grow😭

It does look like mosaic virus, but that need not be alarming. Many roses are affected and only show symptoms when young or stressed. It is not contagious or particularly injurious.

Looks like it to me... my Molineux has it. But is huge, vigorous, and healthy as can be.

Yes. That appears to be RMV.

There is no reason to remove it. 99.5% of the roses available for purchase in the U.S. have it, and the symptoms will pretty much disappear as you move into summer.

It is and they are fine. What Jeri said. They otherwise look like very healthy plants so I wouldn't give it another thought. Just enjoy them!

with all of the above.
A few of my roses have it and it doesn't appear to be life threatening. Like Jeri said, warmer weather (for mine, anyway) lessens the occurrence.
