Peter Ruh of Ohio registered this cultivar of unidentified parentage in 1998. It was originated by Heinz Klose of Staudengärtnerei Klose in Germany and named by Gus Krossa of Michigan in the 1960's. The medium size (15 inches high) mound of green foliage is topped by bright purple flowers in August.

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."

Similar species include H. clausa normalis.
