An article by Herb Benedict in
Hosta Journal (1991 Vol. 22 No. 1) states that, "The
plant that impresses me most in the fall is H. rupifraga
'Urajiro', with its
beautiful deep purple bells. It was imported from Japan by
Hideko Gowen and
obtained from Mr. Nigishi...It has 6 inch wide, very thick green leaves, a white
back and 9 pairs of veins. Robert Harris, of Stone Mountain,
Georgia, and I have
the only divisions distributed of this plant.
There is also a second plant
with the same name. It has narrower leaves, lighter colored blossoms with some
ruffling. It, too, has a white back and 9 pairs o veins...to avoid confusion
between the two, the first H. rupifraga
'Urajiro' is going to
be registered by
Hideko Gowen and Herb Benedict as Hosta 'Grand Slam'..."
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term urajiro as white-backed or white underside.

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'.
