We all worry about different things. I may be naive but I've never worried a lot about HVX. I've bought from the named nurseries but also from local nurseries and occasionally from....I shudder to say it....a big box store if I see a nice healthy looking plant that I want and am certain of the cultivar I get it. I see more at the local nurseries all the time and got Risky Business and Pocketful of Sunshine this week. My problem.....so many Hosta...so little room.
