The Genus Hosta by W. George Schmid (1991), this species is called "the small size hosta" and "The
epithet intermedia used in the synonyms for this taxon indicates
its taxonomic position between
H. sieboldii and
although it is much closer to the former. It is seldom seen in
The Hostapedia by
Mark Zilis (2009) describes this species as "...native to Honshu
high...wide mound of narrow, green foliage...slightly shiny on
top, whitish shiny on the underside...purple flowers...from late
August to mid-Septembers...a little known species, even to avid
collectors...For many years a gold-leaved 'Subcrocea'-type
plant was incorrectly grown under this name..."
Similar hostas include
H. longissima and Hosta
sieboldii forma spathulata. The species name was once
used as the incorrect name for H. 'Kabitan'.
