HVX Example photos. Known "Infected" pics only, Part 2

Am continuing this from part 1 now that some of us are beginning to find infected plants in our gardens.

Largosmom started part 1 with these words

The picture above and the next couple are from my infected Mountain Snow. It only unfurled in the last two days and Chris from Hallson' s said, "Yes, that is Hosta Virus X. The lighter color is right along and radiating out from the veins.

Sorry :("

Another leaf

wow, sorry to see that.
Thanks for showing us what to watch out for.
Guess i need to go do an inspection myself.

My 'Stained Glass' and 'Guacamole' looked terrible early this year, they both frost heaved. They are also both from the same garden center, planted at the same time last summer. New leaves grew out on Guac and it looking a lot better, but I have some serious concerns about SG.

ic_conifers - please post pictures of them on a separate thread here on DG and also on Hallson's HVX forum and if they are confirmed as infected, then post them on this thread as well. The Hallson forum is at: http://www.perennialnursery.com/forums/viewforum.php?f=63 You have to sign up to post, but it's free and Chris is likely the best expert on HVX in the business.

Viola, I won't post them here unless they are confirmed, I will post them in a separate thread.

Elizabeth

this is one I found in our RV Park.... you all said it was infected, and i never posted a photo.

OMG Tee! which Hosta is this?

I haven't had HVX on any of mine yet. I hope it never happens, I guess I'm just lucky. early on I bought some from the box stores. but then I saw what could happen and stopped buying from them and have limited my buying to one catalog nursery. Jim

Oh yes ... for sure Tee! I am glad its not in your yard.
Jim thats a really good Idea, buy all your stuff from one nursery! I use the same cuation with my growers. I dont use but three and one of them do all the TCs around, so I find them above reproach.If something special come up that I cant live without, I would go to Jim's in Dubuque, if he dont have it ... nobody does.

I can't buy all my stuff from one nursery, I like too many different things : ) There really is no one nursery that has all the hostas that I have in my yard. There are hosta breeders within two hours of my house that have 4,000+ cultivars, but they don't have in-stock everything that I want.

ic_conifers, I'm wondering how many really would pass the 10 foot rule? I try to stick to that. there are soo many look alikes that are registered now days. I even find it hard to cull out simular ones of my hybrids. I keep saying, well, maybe I should give it another year. then another. I have over 20 Skylight X Empress Wu crosses. only 3 are impressive. I hope I don't have that problem if I ever have a plant with HVX. a very good friend of mine had a gold standard with the virus, and wouldn't dig it up. I told her that if she got rid of it, I would give her a new one. so she did, Jim

Ahem! We need to keep this particular thread mostly for pictures of plants to have confirmed HVX. Too much other chatter and it won't be as useful.

It was rather cold and wet when the hostas were emerging this year; one week in particular we had close to 5" of rain, which I think contributed to some of them looking a bit distorted.

Anyway, I tested five hostas this spring with the Agdia strips. Two hostas tested positive for HVX, Blue Umbrellas and Earth Angel. The nursery where I purchased Earth Angel just last year took took the situation very seriously. The owner even asked me to bring her some test strips to test a few, which we did. Samples from both her suppliers (reputable tissue culture labs) checked out clean. We narrowed it down to possible cross contamination in her greenhouse, so she is ordering lots of strips and going to do batch testing on her stock.

Here is 'Earth Angel' showing the the collapsed tissue.

The collapsed tissue stands out even more on Blue Umbrellas:

Sorry for the chatter Ann : )

Sandy, do all of the leaves look like that on your Earth Angel and Blue Umbrellas, or just a few?

Thanks,
Elizabeth

Elizabeth, No, only one or two leaves .....

Here's the whole plant of 'Earth Angel'

.... and 'Blue Umbrellas'

Sandy, was Blue Umbrellas new last year, too? I'm trying to get a sense of how soon, on average, a plant will exhibit symptoms assuming it is infected when you bought it. So far I've had two cases that showed signs at the start of their third season in my garden. Really sorry about your latest ones.

Thanks Noreaster. I bought 'Blue Umbrellas' from her in '06. She said her original stock came from the Dutch (field-grown), pre-HVX awareness.

Sandy

Sandy, are you sure those plants in the pics have HVX? I don't see the same blotchiness as the other pics show. yours are just mishapen leaves. but I'm just an observer not an expert. Jim

Jim - Sandy tested them with the Agdia strips. I saw the plants as well. They are infected.
Ann

If you look at her first two pics, you can see the areas of collapsed tissue. With both my cases of HVX on Halcyon and Wolverine, they had the collapsed tissue, but none of the trademark blotchiness or ink bleed effect.

Whereas my Gypgy Rose http://davesgarden.com/community/forums/p.php?pid=3762764 and Mountain Snow (above in this thread) had no collapsed tissue at all. And my Lakeside Looking Glass last year mostly just looked really sick http://davesgarden.com/community/forums/p.php?pid=5123796

Interesting that two of the plants above were purchased in 2006 as were some of Sandy's. That might have been the peak of getting infected plants from reliable nurseries.

I think Chris at Hallson's mentioned in one of his posts on the HVX part of his forum that a plant had to be infected for quite a while to display the collapsed tissue...so maybe it is an advanced symptom and the ink bleed earlier? I imagine different cultivars just display the virus differently, as well.

I remember your Looking Glass, Ann...that sure was a weird looking case of it.

I'll see if I can find that post on Hallsons..maybe I remembered it wrong.

Sandy, Viola Ann, Noreaster, thanks for the explanation, now I'll know what to look for, other than the colors blotching, Jim

bump again

Gold Standard after growing this way for about 4 years (taken last year).

And this year, before being destroyed...

Not my plant but photo taken from a brochure from Iowa State University entitled Hosta Diseases and Pests. You can read it here. http://www.extension.iastate.edu/Publications/SUL14.pdf

it's time this thread was bumped up to be current.

This is my choo-choo train what do you think?

Regal Splendor... not a very good photo..

gardenlady123 - this is a thread for pictures of plants that are CONFIRMED to have HVX. The Choo-Choo Train certainly looks suspicious, but it would be best to have it confirmed elsewhere.

Sorry I forgot. I am upset about how it looks. Will post elsewhere. Thanks.

General question about Hosta Virus X: Does it spread to other plants beyond hostas?

In other words, if your hostas become infected does it also have a negative effect on the plants around it or is it at least contained to the hostas?
