Beautiful, thank you for sharing.
Goofy, it looks like you are growing them in your garden. I am curious under which climate you live (as you have mediterranean spiecies).

Cool, you don't see Dact. iberica in culture that much.

I think your Dact. maculata variegata is catching too much sunlight.

If this is a virus, is it still safe to keep the infected plants with other healthy plants?

It would be relatievly safe if you observe stringent saniatary conditions and rigorous insect control. A virus can move from plant to palnt by physical contact or by tranfer in water or insect vectors. If an insect bites an infected plant and then bites an uninfected plant the virus may be transferred. Likewise if water that has been standing on an infected plant where virus particles have been shed is splashed onto another plant that has an open wound the new plant may become infected. It is best practice to destroy infected plants but if you have something that is rare or hard to find you might want to just quarantine the plant. There appears to be some disagreement whether or not a virus will be transferred in the seed of an infected plant. Also, there is always the chance that another plant may actually be suseptable to a particular virus. Tobacco Mosaic Virus (TMV) infects tobacco, tomatoes and several other species but there have been a number of tomato varietes developed that are TMV resistant.

Interesting. Once I've seen a Platanthera bifolia variegata in nature. It had yellow lines on its leaves. I also believe that this is rather due to a mutation than a virus. I've never seen P bifolia infected or damaged in any way. They are all 100% healthy, but I don't know how they do it. Smile

hey,
in the past, there were many discussions in various forums
about "Dactylorhiza is virus infected or not".

this is, what I found these days in the SRGC forum from Mr. Jeff Hutchins:

...........Variegated Dactylorhiza has been around in a number of nurseries for over 30 years. It first appeared in a nursery in South Yorkshire, and as far as I understand, has only been increased by tuber multiplication. Having got fed up with various judges challenging me,
I got two plants virus tested and both were negative.
If it was a virus, all the populations would have died out long since. As a commercial grower with a large population of Dactylorhizas, I would never keep plants that could cause financial ruin............

as I think, it is also a virus, which makes the cherries red Wink

so what..........
dont worry, EAT CHERRIES Smile

cheers

2 negative virus tests kind off ends the discussion Laughing

There's a lot of conflicting info on the web regarding variegation. I've come across a lot of variegated plants in the wild, you almost always see surrounding plants (even from different families) with the same characteristics. So in those cases it's a pathogen. If goofy's plant was affected by a virus he should've seen it jump to nearby plants, his specimen isn't what you would call a 'mild' form of variegation.

Theres another easy way to find out the truth, and you don't need expensive genetic testing. Take a badly affected leaf from the variegated plant and smash it to get a paste, then cut the stem of a normal plant and put the paste on the wound. If the normal plant stays unchanged the next season, you surely have no virus involved.
...Otherwise you will find a fast way to get more nice variegated plants. Twisted Evil
