The Hostapedia by
Mark Zilis (2009) says, "...native to Honshu Island,
high...slightly shiny, medium green foliage...very shiny
underside...pale lavender flowers...early to late August...This
is one of the lesser known Hosta species."
The Genus Hosta by W. George Schmid (1991), this large size (20 inches high by
26 to 36 inches wide) species was first named and described
Dr. Fumio Maekawa. It is related to
Hosta kiyosumiensis and has
slightly rippled, smooth textured, dark green foliage. Pale
purple flowers with purple dotted anthers
bloom from June into July followed by viable seeds.
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Increases rapidly. Rarely seen in cultivation...An
extraordinarily thick scape, which tends to droop toward the end
of the flowering period."
