Some astute people here informed me I had HVX on a Key West yesterday when I wrongly believed it was color variation. Today, I removed the infected hosta. I also closely inspected my others. I found some fading on one leaf of Stained Glass. This is not near the location of the infected hosta, but did come from the same garden center last year. This hosta does get a couple hours of afternoon sun, and I am hoping it is sun or water damage., but appreciate your expertise. It is only on one leaf.
