This cultivar is a seedling of a Tardiana-type hosta and was registered in 2003 by Peter and Jean Ruh of Ohio on behalf of the originator, Heinz Klose of Staudengärtnerei Klose in Germany. It develops into a large size plant about 19 inches high by 44 inches wide with powdery, blue-green foliage. The leaves are moderately wavy, slightly corrugated and have thick substance. Pale lavender flowers in clusters bloom during in August.

According to The Hostapedia by Mark Zilis (2009), "...may be the most common of Heinz Klose's blue-leaved Tardiana introductions. It may also be the bluest and rivals the best of Eric Smith's Tardianas for foliage color and overall mound appearance. The name "blaufink" translates to 'blue finch"."
