This cultivar was registered by Bob Kuk of Kuk's Forest in Ohio in 1990 as a sport of H. 'Josephine'. It grows into a large size (20 inches high) mound with shiny, dark green foliage that is slightly corrugated and has good substance. Tall scapes (33 inches tall) produce pale purple flowers in late July and into August.

According to The Hostapedia by Mark Zilis (2009), this cultivar "...has always been one of my favorite green-leaved cultivars. It offers shiny, dark green foliage, attractive flowers, and a good growth rate. Leave space for it in your garden."

An article by Warren I. Pollock in The Hosta Journal (1997 Vol. 28 No. 2) states that, "Bob Kuk named this plant for his mother...H. 'Josephine' is relatively unstable. It sports to two different hostas. One has leaves that are all green that he named 'Joseph' after Joe Duale, his stepfather...The other sport he named 'Queen Josephine'...it has green leaves with a wide margin, yellow when it emerges and then becoming creamy white. There is often some slight streaking of the margin toward the midrib...Both 'Joseph' and 'Queen Josephine' are exceptional in that they have very shiny, glossy leaves."
