This non-registered hosta from Japan is a form of H. ventricosa. The leaves emerge gold in the spring but turn green as the season progresses (viridescent). The purple, bell-shaped flowers are borne in July.

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term murasaki as purple and the term ogon or oogon as gold or yellow.
