This fast growing cultivar of unidentified parentage was registered by Ed Schulz of Iowa in 2011. It is a large size hosta about 26 inches high by 42 inches wide with intensely blue-green foliage. The leaves are slightly rippled, moderately wavy, broadly ovate, slightly cupped and moderately corrugated. Near white flowers with light lavender streaking in the middle interior petals bloom from June into July followed by viable seeds.

According to an article in The Hosta Journal, (2017 Vol. 48 No 1), the Ohh! stands for Old Home Hostas.
