=sieboldiana 'Semperaurea'.
Produces yellow seedlings.
This is a very important plant historically, as it was the first known lutescent gold hosta, and possibly the first gold hosta of any kind. It travelled from Japan to Germany before H.'Frances Williams' was discovered. It's a gold sieboldiana type that still makes a pretty good showing in the garden. Own a piece of hosta history! Not very common, despite its age, because few examples have made it over from Germany, where its been hiding all these years.
