This is a selected form of the
species H. sieboldii from
an unidentified originator in
Japan that was registered by
Kevin Walek (Hosta Registrar) in 2009
and
re-registered
with new data in
2018. It forms a semi-upright mound about 15
inches in height by 35 inches wide. The olive green leaves have
a creamy yellow to white marginal variegation and are slightly
rippled, dull on the top and bottom and are elliptic with a
tapered base. Medium purple, tubular flowers with pale lavender internal strips
bloom in August. At the time of registration, seed set was
unknown.
According to
The Hostapedia by
Mark Zilis (2009), "...listed under a variety of
names, including 'Mishima Fukurin Koba', 'Mishima Fukurin', and
H. albomarginata 'Mishima Fukurin'. The plant being sold
is the same as 'Koriyama'."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term koba as small leaf,
'Koba Gibōshi' or
H. sieboldii and the term fukurin as margined or edged.
