Registered by Liberty Hyde Bailey of Michigan and The American Hosta Society in 1987, this cultivar is of unknown origination and unidentified parentage but it assumed that H. 'Fortunei' is in its genetic background.

This is a large size hosta about 25 inches high by 48 inches wide with dark green foliage. It bears lavender flowers on scapes about 40 inches tall.

According to The Hostapedia by Mark Zilis (2009), "The name H. fortunei 'Aoki' was registered by the AHS in 1987 for leaf show purposes (Eisel 1988, p. 60). When Hosta fortunei was no longer recognized as a species (Schmid 1991, p.50), the name H. 'Fortunei Aoki' was proposed for this plant (ibid, pp. 51 & 159). This was an awkward combination of a Latin specific epithet (fortunei) and a fancy name (Aoki). Instead, H. 'Aoki' makes more sense as a stand-alone name."
