This cultivar is a sport of
H. kikutii caput-avis from Japan. It has shiny foliage that arches and gives a drooping
appearance. The lavender flowers are borne from
mid-August into September on long drooping scapes.
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term nakafu as medio-variegated.
