Originated in Japan but imported to the U.S. by Marge Soules of Indiana, this non-registered cultivar is a sport of H. kikutii caput-avis. It is a small size hosta with green foliage.

According to The Hostapedia by Mark Zilis (2009), "It may be the same as the plant I named 'Unazuki Dwarf'."

"Plant's neme is the Japanese academic name for H. kikutii caput-avis...In North America it is used as a cultivar name for a selected, small clone of H. kikutii caput-avis. The horticultural application of a Japanese academic name is technically incorrect because this name applies to all the natural populations of this taxon, not just a selected clone. For this reason I have added the importer's name to the cultivar name, as H. 'Unazuki Soules', to make this clonal cultivar name acceptable under the ICNCP."
