This species is called the "thick leaved hosta" according to The Genus Hosta by W. George Schmid (1991) ." Morphology points to interspecific hybrid origin. It is rarely available and only a few specimens exist in scientific collections and herbaria."

The Hostapedia by Mark Zilis (2009) says, "...native to Mt. Ibuki in Japan and related to H. montana... large size mound of thick substanced, green foliage...Throughout my travels in Japan, I never saw this plant and doubt that any Japanese collector I met knew about it."

The species has bright, medium green foliage that has thick texture and is ovate-oblong in shape. It bears bell-shape white flowers with purple anthers.
