Where does H. 'Blue Hawaii' get its fragrance
I noticed this hosta on the fragrant flowered hosta list. I do not have it, but I was checking out its parentage/lineage in MYHOSTAS.BE and also at Wade & Gatton's shopping list.
I cannot figure where the fragrance comes from. It is described as "lightly fragrant."
Are not all fragrant hosta from the plantaginea line?
Or maybe some other hosta species has fragrance?
Any help here and a picture as well, would be appreciated.
