cultivar of unidentified parentage was registered by
Dr. Ralph (Herb) Benedict of Michigan in 1983. It forms a small
size, somewhat upright mound of
twisted, wavy foliage that comes to a pointed tip. The medium
lavender colored flowers bloom in very late August.
The Hostapedia by
Mark Zilis (2009), "...appears to be the same plant
as 'Hamada Contorted' and both come close to 'Koryu'...impressed
with its odd, twisted foliage and "green-on-green" variegation."
An article about Fall Bloomers by
Herb Benedict and
Jim Wilkins in
Hosta Journal (1991 Vol. 22 No. 1) states that, "Here
are some of the fall blooming plants we grow...(listed in the order of bloom
times in Michigan).
|1) H. kikutii
||A medium size plant densely flowering

Nomenclature changes recommended in the
1991 book The
Genus Hosta by W. George Schmid and accepted by The American Hosta Society would update names as follows:
H. tortifrons is now H. 'Tortifrons'
and H. tardiflora is H. 'Tardiflora'.
An article about H. 'Koryu' by Warren I. Pollock in
Hosta Journal (2001 Vol. 32 No. 2) states that, "Tony (Avent) goes on to explain: "This very distinctive collector's plant, a
H. longipes (selection or hybrid) which is highly coveted in Japan, was originally
discovered by Dr. Shuichi Hirao. This is the same plant the
Benedict named H. 'Fused Veins', after not being able to determine the true
