This small size cultivar is
"probably" a sport of
H. longipes from Japan which was originated by a
Kichigoro Suzuki. Its ovate foliage is green with yellow medial
(center) variegation and has rich red petioles. Leaves are very shiny underneath, slightly wavy and
have heart shaped bases. It has dense clusters of pale purple flowers
with purple anthers borne on
20 to 30 inch scapes in August into September.
The Hostapedia by Mark Zilis (2009), "...I am quite impressed with this cultivar. The
variegation is striking and the rich red petioles add to
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term
-gawa or -kawa as river and the term iwa as rock, Iwa Giboshi or
H. longipes and the term nishiki as brocade (rich-colored woven fabric) i.e.
something colorful and beautiful.
