This cultivar
which has been on the market for a long time in
Japan was originated by
Dr. Fumio Maekawa but registered by
Kevin Walek (Hosta Registrar) on his behalf in 2009. It is a sport of
H. sieboldii which grows into a
small size plant only 8 inches high and 22 inches wide with
medium green colored foliage that has a white marginal variegation. The leaves
are slightly rippled, ovate and dull on top. Pale to medium lavender, tubular
flowers bloom from August into September. It sets seeds but the viability was
not known at the time of registration.
According to
The Hostapedia by Mark Zilis (2009), "According to
Kenji Watanabe (1985),
the names Chishima Gibōshi and Shirofukurin Chishima Gibōshi
have been incorrectly used for Hosta 'Bunchōkō'."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term shirofukurin or shiro fukurin as white-edge(d) or
white-margin(ed).
An article by Warren I. Pollock in
The
Hosta Journal (1991 Vol. 22 No. 1) states that, "The
name on the label was 'Bunchuko', but according to
W. George Schmid it should be
'Bunchoko'. This hosta looks like 'Ginko Craig'...H. 'Bunchoko' has dark purple
blooms much darker and more handsome than 'Ginko Craig'...I confirmed this
difference with our still blooming 'Ginko Craig' and also 'Princess of Karafuto'
which is a 'Ginko Craig' look-alike."
