The spread of Hosta Virus X seems to be reaching epidemic proportions. Here is an update:
I've decided to make this an announcement so that it doesn't get lost.
The number of virused plants that are coming over from Holland is staggering at this point. But it is not isolated to just Dutch plants, as some US wholesale growers have it too.
I can confirm that the following plants have tested positive for HVX either from plants we got or from other results from other people's plants or from other reported results. We have destroyed all plants that either had or were suspected of having the virus here at the nursery and have tested all of our remaining stock of any of these plants.
Birchwood Parky's Gold
El Nino (from 2004, the 2003 plants tested negative)
Sum & Substance
This does NOT mean that every plant of these varieties out there carries the virus.
We will be getting every single Dutch plant here tested and will randomly test our own stock, domestic stock, and absolutely anything that looks suspicious.
Hang in there with us
This spring we purchased plant stock of Hosta 'Goldrush' from Darwin Plants, Holland, and several of them came up with a spotted and mottled appearance.
So we put them aside until they could be tested. I sent leaves off to the University of Minnesota and just as I suspected they are infected with HVX.
I spoke with a forum member who knows someone else who received Goldrush from Darwin's and they too showed the mottled appearance, so anyone who has purchased this variety should be on the lookout.
Here is a picture of Hosta 'Goldrush' with HVX.
Since these plants were not ever divided or propagated here at the nursery I am confident that we did not spread it to our own plant stock. Also, whenever I divide plants I disinfect my tools with alcohol both before and after making any cuts. That disinfecting step is getting more and more important with the fast spread of this virus.
I sure hope that these wholesale growers get their act together. If not the government agencies regulating and inspecting them should shut them down, in my opinion
