'Wishing Well' is prized for holding its beautiful blue color long into the season, even when planted in 2/3 day of sun. Its huge leaves emerge slowly, exhibiting a unique cupped, rippled, and corrugated texture. They unfold slowly as they mature. Since they are of thick substance, the leaves are more slug resistant. Wishing Well has a good growth rate compared to some other large blues. The near-white flowers begin to appear in midsummer and last into late summer.
