Susan,
I have kept records of all hosta purchases I have made in the last 15 years or so. I have not bought any but one last year at Lowes. I will. keep an eye on it and lucky it is away from my other hosta. Most I have had for years and didn't buy any in the last 4 years. Didn't know about this virus and I don't know when it started hitting us. I am going to tell all my friends about this. So far I believe my plants are safe. I am scared now to purchase any hosta. I was releaved to learn that insects or deer can't spred this virus. Just us using tools and hands. Still very scary stuff.
