This cultivar is a sport of H. 'Urajiro Iwa' found in Japan. It is a small size hosta with green foliage that has a white marginal variegation. The leaves are narrowly ovate and slightly wavy.

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, the term shirofukurin or shiro fukurin as white-edge(d) or white-margin(ed). and the term urajiro as white-backed or white underside.
