This large size (21 inches high) cultivar of unidentified parentage has slightly cupped, wavy foliage. It bears very light lavender flowers in July. It was registered in 1987 jointly by The American Hosta Society and Dr. Nils Hylander of Sweden.

According to The Hostapedia by Mark Zilis (2009), "Though being around for over fifty years, 'Fortunei Rugosa' is unknown to most hosta collectors. It differs from other Fortunei types by its unruliness and heavy corrugation and would be a useful breeding plant."
