This particular iris has small purple streaks on the falls. If this was a registered cv I am unaware of what the name is. Could this be a sign of a virus like tulip breaking, or just poor genetics? Or is this something desirable? Thanks for your help.

I've never heard about any kind of virus or disease on iris blooms. Your plant looks fine to me.

However there is such thing us iris people call as the iris virus. (Aka: an addiction of growing iris)

We had a thread on virus diseases in irises a year or two back, but I don't recall if any of them displayed the symptoms seen in your pictures.
However, it's not uncommon for iris blooms to sometimes have darker spots/striations, usually purple. In some cultivars it is a permanent feature, in others it comes and goes without any ill effect on the plant as such, as far as I know.
There are others here on the forum, who are more knowledgable about these things, maybe they will chime in.

Last year we had a frost as some irises had buds ready to bloom.
I don't use chemicals (except antifungals) on anything, so when I see something like this, I am at a loss for what can cause it, except maybe some stress from the late frost.

This is Superstition, with unexplained and unexpected speckles. the sisters and daughters are all from the same clump, and not all of them had it.

I dunno.

Thank you all for your opinions. I am pleased to finally settle this in my mind!

I call it Confetti and I love it. At least part of the time, I believe it is genetic because some Irises are actually named in a manner that references the Confetti. I will have to see if I can find you some. Also it is consistent on some of my Irises from year to year and it never spreads to other Irises. I am not an expert on this type of stuff so I am basing this on observation.

Here are some Irises that have confetti: Birthday Confetti, Sue Zee, and Colortrak. I know I have some others. I actually have a seedling of Sue Zee and it has Confetti as well. To the best of my knowledge though, confetti is just a descriptive word used to describe the pattern they see, I don't think it is anything official. I think some people out here have been judges. Hopefully they or others in the know can weigh in.

here are some photos of the irises @greeniris mentioned:



couldn't find a photo of the 3rd iris.

Daphne, Elsa, I found the Birthday Confetti online. In the description it mentions the markings as "irregularly splotched purple." The other 2 descriptions does not address the streaking. It is consistent in my orange iris and I'm happy to know it's probably genetic. As I acquire more iris from my enabler @lovemyhouse it may have to go the way of the dodo ie: neighbors. Thank you!

Thanks Daphne for showing the pics.

Another point: One thing you can see too in some of these is that they also have the streaks or confetti for different growers, again hinting genetic. I have bought Irises for this trait as I think it is cool. Another Iris I though of with this trait is Rose Tattoo.

Honey Glazed also has this type of pattern. I like it a lot and have oodles if anyone wants.

I always thought it was weather related... Some Iris I have seem more prone to it, but don't do it every year.
Interesting article on W. R. Dykes and the streaking being mosiac virus..

This is interesting Sherry and makes me a little sad, that at least in some cases, I may love a trait caused by disease.

It is very definitely a virus,likely mosiac virus. It is in the plant and there is nothing you can do about it. Discard it or live with it, but definitely but don't send plants elsewhere unless someone insists.
