I had Maria Stern for afew years. Finially had to toss her because the RMV got so bad, it looked like a speckled leaf rose. Bloom production also went down. Was a very beautiful rose while it lasted.

You shouldn't have to worry about it affecting other roses in your garden.
It might shorten the life of the plant, of course.
Even out here in SoCal, I believe it often shortens the life of the plant.
But other than that, no worry.
Would you mind telling us who the grower was?

I just discovered that two of my grafted Brownell's which
I have had for years have RMV....two Charlotte Brownells and one of my Rhode Island Red climbers. I have read somewhere that most of the grafted Brownells are virused, but I was hoping I would be one of the lucky ones. This
will be the first incident of RMV ever for me. The sad thing is, both of my virused Charlotte Brownells have been the most productive bloomers of all my hybrid teas.
For years they put all the others to shame. Since nothing is blooming here until next month, I don't know if the bloom quality will be the same but in terms of the bush and foliage they are growing vigorously and setting loads of buds. I know they will eventually start to decline, but so far, the only telltale sign was the leaf markings which are now fading into shiny green now that the weather has warmed up. If I hadn't seen the markings earlier I would never guess these
were virused roses. The problem here in zone 4 is that
these poor plants have a lot to face going into winter. Its hard enough on the healthy roses! I plan on keeping them just as they are until they look sickly. They have
brought me years of pleasure so I will have a hard time
parting with them. I don't believe they pose any danger
to surrounding roses.
Sorry about your Maria Stern. So far mine has not shown
any signs, but I would not be too surprised if its just
a matter of time.

Dutch Gardens! I should have known better after reading Dave's Garden Watchdog about them. Not the best. Next time I'm going with Pickering Nurseries for her.

But prepare for the possibility that there may not be any un-virused stock.
Like Celeste, you may find that the virused plants may still serve you well for a long time.

What a shame! You have gorgeous roses! I will keep her for now, maybe replace her at Pickering Roses next spring. If she makes it through winter. Maybe I didn't get the "real" Maria Stern! You never know unless you go through a reputable place. I now know about Dave's Watchdog and won't even consider Dutch Gardens again! Just a bad as J & P!

I just thought of another question. If, she doesn't make it through winter, can a different rose be planted in same spot? I know about the "sickness" diease, but if I replace the soil would the virus have spread there and infect the new one?

Rose Mosaic Virus is a collective name for a group of viruses that infect roses with mosaic symptoms. The most common one, PNRSV, is a temperature sensitive virus. In your zone, I would be concerned about it spreading to your other roses. There is another on going thread that will give you the background on this subject, see:

Here is a link that might be useful: Another RMV thread

If you dig a BIG hole, and replace ALL of the soil -- making sure not to leave behind dead feeder roots, you should be fine.
