The mighty hosta is no super hero, but its nemesis Hosta virus X sure is. Hosta virus X (HVX) is a rather new disease of hosta that has become a regular visitor to the Plant Diagnostic Laboratory. We get samples of hosta with the disease once or twice every summer, usually from a nursery, and we just got this year’s supply.
