What's Wrong with my Krossa Regal?

This got hit by the frost this spring. It's growing in full sun, but generally just looks sick. The second flush of leaves are looking like this:

What do the backsides of the leaves look like?

That kind of looks like what's on my Cathedral Windows. The "guys" said they thought it was sun and stress.

Hi Gesila,

Is there a bit of a mosaic pattern on some of the leaves or am I seeing things? I'm wondering if your hosta might be infected with impatiens necrotic spot virus which might explain the dead spotting. The dying edges could be from under-watering or over-watering. I don't think this is the same thing as the Cathedral Windows. I think the Cathedral Windows is just heat/drying damage - maybe there was an especially hot, dry wind one day that did a little damage there some time back and it is just now turning brown.

Sorry, but something doesn't look right with that Krossa Regal.

Chris
