Apparently, plum pox actually can be transmitted through seeds:
But these apricot seedlings didn't actually get the disease, even though they came from infected trees:
In other species, for other viruses, seeds are generally a safe way too get virus-free plants. I know, for instance, that lilies are often grown from seed to avoid viruses that infect vegetatively-propagated plants. Of course, that might not be relevant to this virus.
" PPV was introduced into several European countries via
infected nursery stock or infected buds grafted onto
healthy trees. This is the only known method of long-distance
This one little apricot seedling of mine looks perfectly healthy.
I guess everyone has to make up their own minds about whether or not they want to risk planting these. Let me know if you'd still like seeds.

Great point Scott: is there any way we can tell if the plant has Plum Pox while it is still growing inside the house/quarantined before planting it outside where it could infect local stone fruits?
Sarah, if you search the web you will find many pictures of the leaf damage, if it is as obvious as the samples they show in the pictures it seems pretty easy to detect. It is also good to look at the map of the world to see where it is present:
I have grown out a few prunus seeds from overseas but only from the non-red countries. Afghanistan is not red but the government is so fractured there it may be just a lack of information; Iran next door is red. Overall I feel its best to be very conservative on this disease, it has overrun Chile and it could do the same in the US.
