'Zitronenfaller' is a wrong writing. The correct name should be 'Zitronenfalter'. With a "t" after the "l".
It's a german word. 'Zitrone' means lemon. 'Falter' means butterfly.
In Germany we have a butterfly, called "Zitronenfalter", because of it's color.
The latin name of 'Zitronenfalter': Gonepteryx rhamni)

So it must have been a german or austrian breeder who gave this name to that hosta.
