2012 Peony Viruses

A couple of my peonies have been affected by viruses. The virus seems to affect the same peonies every year. I don't think there is anything you can really do to get rid of it. Viruses in humans are not curable by any medicine, the symptoms can be controlled or suppressed, but the immune system of the body is the only thing that can actually defeat the disease. So either the peony would have to fend it off on its own or find a way to live with it. It seems that most of the time peonies can live with a virus without the plant being too adversely impacted. Also I've noticed that several of the peonies I have planted in shade have a virus. So it seems like peonies that are stressed because they are not planted in ideal conditions are more susceptible to viruses. Those virus infected peonies that I have seem to bloom just fine and are able to increase as well. Most of the time, the foliage of the entire plant is not affected. Sometimes only a portion of the plant is diseased. I'd be curious to see if you divided the plant and threw away the infected portion if the plant would be virus free or if the virus would come back the next year. That may be an experiment for another day...
