Viraraghavan Roses
Comments (5)There were two found plants of Anna Olivier here in Santa Cruz, and their growth was completely different. One was in a shady area, had one trunk-like cane growing 6 or 7 feet tall, with small branches off it. The plant I grew from it is about 4 feet high and very open and spreading. The other found plant was like a five foot gumdrop, lots of small branches, a fairly dense plant. From my experience, I'd say you can get it to grow any way you want, but it will be denser with more sun....See Morequestion about rose mosaid virus
Comments (14)seil z6b MI stated: "With everything else there is to worry about out there right now RMV is low on the list for me. It's not the Grim Reaper some other things are." H.Kuska comment. That is fine for you, but I feel ( from my experience in two zone 5 rose clubs) that it is very possible that many new cool climate gardners purchased one or more virused roses only to find them decline and die in about 5 years. And then they gave up and went to other plants. The following is what Help-Me-Find states on the subject: "Symptoms of RMV can include bright yellow banding, yellow netting, unequal leaf margins and leaf distortion, less winter hardiness than virus-free specimens, diminished flower production, reduced plant size and reduced vigor. Strains of viruses differ in their virulence. Infection by some strains is almost symptomless." H.Kuska comment. Please notice the "can include" and "less winter hardiness than virus-free specimens". From what I have presented about the temperature dependence of the roses immune system, I expect that warmer climates will have less of a problem than colder climates. http://www.helpmefind.com/rose/gl.php?n=293 Apparently there are now 11 known viruses. I would not be surprised to find that more northern virused roses have died due to being weakened and then not able to withstand cold winters than the number of deaths from rosette virus. Since there are different strains of even the same virus and since there are expected to be different immune system efficiencies in each hybrid, there will always be examples of some virused roses living well in northern climates. ....See MoreRose Mosiac Virus @ K&M Roses
Comments (12)Frank- No, you don't have to start all over. What variety did you get from Mr. Mills, if you don't mind me asking? Not everything I've ordered has been infected, so you might be ok. Even if, by chance, the one you ordered does have it, it shouldn't be a problem for you as far as the disease spreading. I just read an article published on the ARS by Malcom Manners stating that the only way of transmission is through grafting. Some people go to the extreme and dig the plant up and burn it. I don't see any point in this as I've never had it spread from one rose to another. The biggest problem for me is that they just don't grow like a normal rose. Much less vigor, flower size distortion, color distortion, and winter tenderness. Also very hard to exhibit an RMV rose unless it isn't showing. Even then you run the risk of someone taking your rose home from the show to root it. My advice: keep it until you find a clean version of it. It may still throw off some nice flowers and grow ok for you. Then again, it may be lackluster. Either way though, DON"T start over! Good luck with your new rose garden!! Kentucky Rose- Yea, the roses had it upon arrival. I didn't plant them in the ground. I ended up planting them in pots until I can get replacements for them. I didn't want to take up good spots in the ground for sick plants so I just potted them up. They are growing, just slower than the rest. I have exhibited a rose with RMV one time. I actually won Princess with her at the Tenarky Districts last year, in fact. The Variety is Bugatti (do not buy it from Mr. Mills!) and it's one of the few that doesn't seem to show symptoms much. But, like I said before, it just generally lacked vigor and I was always wondering how much better she really should be. Just seems kind of pointless to me. I had thought about just paying Mr. Mills and being done with him but the more I thought about it the more it angered me. How many people does he get this over on and how many people just say to hell with it and just pay him? Not doing it this time. Last time I gave him nearly 550 dollars just to have roses I already paid for show symptoms halfway through the season. Half the first ordered showed immediately, and the other half started showing up throughout the summer. I decided he wasn't taking me to the cleaners this time around....See MoreFirst report of rose rosette disease caused by Rose rosette virus on K
