According to The Hostapedia by Mark Zilis (2009), this plant is "...not considered a legitimate cultivar; name used for at least two types of hostas, one being a green-leaved Fortunei with tall scapes, the other a large H. 'Sieboldiana'-type; treated as a synonym for H. 'Elegans' by Schmid (1991).. .The name H. fortunei 'Robusta' was used by Georg Ahrends in 1905 for the plant that eventually became H. 'Elegans'..."

In 2005, Peter and Jean Ruh registered this plant (Fortunei type) as H. 'Robust Giant'.

Seedlings of this cultivar include H. 'Neat Splash'.
