This cultivar was listed on the MyHostas Database website. Originated in Japan, this non-registered cultivar is of unidentified parentage. It is a small size mutation of the wild form of H. sieboldii (aka H. albomarginata) with yellow foliage that changes to chartreuse in color later in the season.

MyHostas speculates that this is the same as H. 'Ogon Koba' or H. 'Wogon'.

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term koba as small leaf, 'Koba Gibōshi' or H. sieboldii and the term ogon or oogon as gold or yellow.
