The following map gives an approximation of where the Hosta species grow naturally. If you want more detailed maps, please refer to pages 308 to 315 in The Genus HOSTA by W. George Schmid (1991),.


When W. George Schmid created the map shown here in 1991, there were 43 accepted hosta species. In 2010, Schmid decided that H. sieboldiana was actually not a species found in the wilds so it was reclassified as a cultivar, H. 'Sieboldiana'. This change was then accepted by The American Hosta Society. So, the location for #34 on the map is incorrect.
