This is one of those cases where
a hosta has been known for a number of years under one name but
evidence arises that it was named something else at an earlier
date. That earlier name takes precedence when it comes to plant

montana (Mount Fuji-type) was originated in

Mark Zilis of Illinois and
American Hosta Society in 2012. It is a large size plant about 22 inches
high with a spread of around 48 inches. The leaves medium green
with a yellow medial (center) variegation which has some streaks

slightly corrugated and dull on top. Pale lavender, tubular
flowers with lighter lavender margins bloom in July.

golden yellow in the center but turns green by mid-summer. It
emerges 2 or 3 weeks later in the spring than forms of H.
montana that come from other areas of Japan. This may help them
to avoid damage by late season frosts like other types from this

H. 'On Stage", with a note that 'On Stage' is the same hosta as 'Chōkō Nishiki'.
Originator of 'Chōkō Nishiki' was possibly thought to be Mr. Hisatoyo Asami of
Tokyo, a long-time member of The American Hosta Society. An inquiry to Mr.
Hisatoyo Asami determined that though he purchased the hosta around 1980, he was
not its discoverer or originator. Furthermore, Mr. Asami does not know who named
