Nomenclature changes recommended in the 1991 book The Genus Hosta by W. George Schmid and accepted by The American Hosta Society would update names as follows: H. x tardiana is now the Tardiana Group.

Not so. There is at least one exception: Eric Smith's 'Hadspen Honey'. According to an April 5, 1978 letter that Smith wrote to Alex J. Summers who was then living in Roslyn, New York, "H. 'Hadspen Honey' is a sport from the golden-edged H. 'Sieboldiana'," that is, from Hosta 'Frances Williams'."
