I've had 'Moonstruck' for several years. First year, the centres of the leaves melted out big time. So I moved it to the east side of my house. It's generally done reasonably well here until recently. A couple of years ago I took a division as a special request and it pouted at me for the entire summer. This year, after a slow, wet spring, it's already melting out in June. (Mind you, all of the hostas in that spot except June are showing signs of sunburn - probably because it was so cloudy and wet for so long then the sun in June was too strong).
Anyway, I'm just about ready to pull this one from my garden completely. Has anyone found the secret to growing it well?
