This cultivar from Japan was originated by Dr. Fumio Maekawa and registered by The American Hosta Society on his behalf in 1987 as a sport of H. 'Tokudama'. It is a medium size plant with blue-green foliage that has a gold colored medial (center) variegation. The leaves are heavily corrugated and broadly ovate. It bears near white flowers in dense clusters from late June into July.

According to The Hostapedia by Mark Zilis (2009), "Over the years I have seen a few specimens labeled as such and have even propagated them, but they appear no different from 'Tokudama Aureonebulosa'. In fact the juvenile form of the latter can easily be described as yellow in the center with a narrow, green margin, so I do not believe that the name 'Tokudama Flavoplanta' (or H. tokudama flavo-planta) can be correctly ascribed to any plant."
 

An article about H. tokudama 'Flavoplanata'  by Warren I. Pollock in The Hosta Journal (1985 Vol. 16) states that, "Prof. Dress states that the "planata" part of this epithet is not Latin; that is, there is no such word or form in Latin, so far as he can determine."
