Looks like the streaked version of kikutii f. leuconota.
This stunning selection of Hosta kikutii was imported to the U.S. from Japan by Minnesota's Hosta Guru Hideko Gowen.
H. 'Hyuga Urajiro' features frosty blue spear-like leaves with yellow streaks.
The undersides of the leaves have a metalic silver coloration.
A true collector's gem.
