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

Originated by Dan Wols of Illinois, this non-registered cultivar is of unidentified parentage. It is a large size, H. 'Sieboldiana'-type hosta with bright yellow foliage. The broadly ovate leaves are moderately corrugated, slightly cupped and are slightly upright in form.
