This is one of those cases where there are two hostas with the same name. Neither is registered with The American Hosta Society. The first one to be registered would become the "official" hosta of that name and the other would have to be renamed.

Originated in Japan, this non-registered cultivar is of unidentified parentage. It is a small size hosta with green foliage that has a white marginal variegation. The leaves are narrowly ovate and heavily rippled. It resembles H. 'Ginko Craig' and has a fast growth rate.
