The Hosta that so far appear to be doing the very best are
Earth Angel
Wide Brim
Ivory Queen
Sum and substance
Diana remembered
Minuteman
And 1 Liberty
Twilight
Moonstruck
All of these are receiving solid shade or sprinkled shade with the exception of Diana who is receiving more sun.
The ones struggling are
Loyalist and 1 Liberty
Most like this is a location problem.
