Peter Ruh of Ohio registered this upright cultivar of unidentified parentage in 1997 and modified in 2022.  It was originated by Heinz Klose of Staudengärtnerei Klose in Germany and named by Gus Krossa of Michigan in the 1960's.

The fast growing medium size (17 inches high by 20 inches wide) mound of light green foliage. The leaves are slightly rippled and have pink petioles with the color extending up into the leaf. Deep purple flowers bloom from July into August on scapes up to 26 inches tall followed by seeds in purplish pods.

 The registration materials state: "2022 Correction to Originator."

According to The Hostapedia by Mark Zilis (2009), "It is a derivation of Hosta clausa, except for the fact that the flowers fully open and it readily forms seed pods. Pete named this plant for Gus Krossa's hometown in Michigan."

This plant was once known as "Klose Seedling HK-10".

Similar hostas include H. clausa normalis.
