Zuzu said in another thread that her carmella was from ru, but has shown no signs of virus.
Last year, I read about lily virus and was inspired to move my tiger lilies to a different garden to be away from my regular lilies. (These are the actual tiger lilies with the little bulbs along the stem not the orange ditch lilies that people call tiger lilies). Tiger lilies can carry the virus and not show symptoms. Lots of "experts" strongly recommended that they be away from oriental lilies. My tiger lily was a "rescue" from an abandoned garden by a fire damaged building barely surviving under piles of lumber and debris. All my other lilies look fine (albeit crowded because they multiplied over the winter). Very few people garden around here. I haven't seen any other lilies in town. I don't think that lily virus is a concern in my garden unless I buy new lilies from a disreputable vendor. It seems that lily virus can be spread by pollinators or garden tools. I have a couple tiger lilies popping up again in the original garden bed near the coral carefree celebration rose. I think they will look nice together, so I am leaving them there this year!
From what I have read, hosta virus seems to be the most easily spread. It also seems to seriously weaken the plant. Two women were talking about hosta virus at the local Lowe's and pointing out plants to the manager - buyer beware, I guess. I didn't get a look at the plants or a chance to talk to the ladies, was in a hurry that day. I only have a few hostas including a huge green variety (perhaps sum and substance) plotting world domination. Have to admire any plant that can grow in deep shade under black walnut trees with little care, but roses are much sexier.
I have only seen pictures of rmv, not the real thing. Most pictures show the yellowing of the leaves, but one site showed "broomstick" growth where the rose foilage was very deformed. Do you encounter mostly the discolored leaves?
