The Genus Hosta by W. George Schmid (1991), says that  this plant is called the "Fuji Hosta". It inhabits wet bottom lands of mountain valleys in its native Japan." Morphologically midway between Hosta sieboldii and H. rectifolia, it has very long, winged petioles and beautiful, purple striped, bell-shaped flowers. The species epithet comes from callianthus = with beautiful flowers."

The Hostapedia by Mark Zilis (2009) says, "...native to Honshu Island in Japan... medium-size mound of green foliage with purple flowers from mid-August to September...similar to H. rohdeifolia..."

This is a medium size hosta about 16 inches high by 16 inches wide with dark green foliage. It bears purple, bell-shaped flowers with yellowish anthers from August into September.
