According to The Hostapedia by Mark Zilis (2009), this cultivar is the same as H. 'Ani Machi' which was originally registered by Dr. Kevin Vaughn of Massachusetts in 1983 but that registration was subsequently revoked (see comment below).

The Hostapedia by Mark Zilis (2009) states "This is a case where the plant being sold is not the same plant that was registered...Differences can be found in the foliage color, mound size, leaf size, and flowering habits (color, scape height, and time)."

On March 30, 2021, we received an email from Gayle Hartley Alley, International Registrar Genus Hosta stating: "After many years of conflict between the registered hosta 'Geisha' and the plant marketed with the same name, I am rescinding the registration on this cultivar. An updated Cumulative Index is available from the Hosta Treasury at: http://www.hostaregistrar.org/hosta_registration_lists.html . The name 'Geisha' has been removed from the index pages and now appears in Appendix B (page 78). An official notice will appear in the "Corrections and Comments" section of the Registrations 2021 booklet (distributed in spring of 2022)."

An article about H. 'Ani Machi' and H. 'Geisha' by Warren I. Pollock in The Hosta Journal (2001 Vol. 32 No. 1) states that H. 'Ani Machi' according to Mark Zillis' book The Hosta Handbook (2000)  "is the same plant that has been sold as H. 'Geisha'. It is not, however, the plant that Kevin Vaughn registered under this name in 1983." Vaughn registered a much smaller plant that what is in the trade today as H. 'Geisha'...he confirmed that what is on the market as H. 'Geisha' is not what he registered."
