I hate to play devil's advocate, but isn't it possible two plants across the world were given the same name legitimately, but without cross referencing with one another? I imagine before the Internet this would have been an easy mistake to make. We could list them as 'State Fair' (US Source) and 'State Fair' (German Source), use a "from" reference like we do with some species, or tack on "Tufted" to the name as Kevin suggests. Just some ideas.
