According to The Hostapedia by Mark Zilis (2009), this non-registered cultivar was found "...near Mt. Fuji by Kenji Watanabe, Gotemba Nursery, Gotemba City, Japan "

It forms a medium size (18 inches high by 48 inches wide) mound of bright green foliage that is smooth-textured, has a wavy margin and a thin tip. Perhaps its most distinctive trait is the light purple, double (hose in hose type) flowers produced from late July into August.

Zilis (2009) goes on to say, "...'Fujibotan' is a must for any hosta collector. It forms a very attractive mound of clear, deeply veined foliage, and its show of double flowers is simply spectacular...Though it is listed as a  H. montana type, it shows evidence of being a hybrid, possibly with H. sieboldii..."

From the Field Guide to Hostas by Mark Zilis (2014), "This may be the best double-flowered hosta cultivar in existence, in the sense that it is the most consistent double."

The Hosta Journal, (2006 Vol. 37 No. 2), contained an article in which several hostaphiles were asked to give a brief list of their favorite hosta flowers. This plant was included in that list.
