Pandora's Box hasn't been a problem for me so far. I've had it for several years and it's done well. Now watch...this is the year it won't come back! Nougat does keep its color throughout the season, but it looked like it was getting some solid leaves last year. I'll have to watch it this spring. I moved all of my minis and small hostas into a new bed last year so I'm waiting to see what likes the new location. I hope all of them do!
