Originated in Japan, this non-registered cultivar is a sport of H. kikutii polyneuron.  It is a small size hosta with green foliage that has a white marginal variegation.

According to The Hostapedia by Mark Zilis (2009), "The cultivar name indicates that this plant was found on Shikoku Island in Japan, but I can see no obvious difference from 'Shirofukurin Sudare'..."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term shirofukurin or shiro fukurin as white-edge(d) or white-margin(ed).
