There is an image of this
cultivar on the
Hosta Library. From the photo on the HL website, it appears to be a
miniature
size hosta with slightly twisted, dark green leaves of
thick substance. There appears to be some red dotting on
the short petioles. This non-registered cultivar was
originated by
Sakata of Japan.
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term iwa as rock, Iwa Gibōshi or
H. longipes.
