According to The Hostapedia by Mark Zilis (2009), "H. kikutii 'Prunose' = H. kikutii leuconata "

An article by Dr. Ben J.M. Zonneveld in The Hosta Journal (1996 Vol. 27 No. 2) states that, "...I found in the garden of Hideko Gowen,..I also found a seedling of H. 'Salute' (a H. rupifraga × H. kikutii prunosa cross or, is H. 'Blue Cadet' also involved?). It had a total of eight scapes in bud...The peculiar thing was that there was just a single crown with about eight leaves. Surely a plant to give some attention."
