We suspect that the top two images are of the plant with the Hosta nakaiana background while the bottom one is probably from Hosta gracillima. The flower could be from either one.

This is one of those cases where there are two hostas with the same name. Neither are currently registered with The American Hosta Society. The first one to be registered would become the "official" hosta of that name and the others would have to be renamed.

This is an old, non-registered cultivar that is found in two forms in the nursery trade. One form has H. nakaiana in its background and forms a mound about 10 inches high with a spread of 30 inches. It has ovate shaped, slightly wavy foliage that has a smooth texture and average substance. The pale purple flowers bloom starting in late June.

According to The Hosta Handbook by Mark Zilis (2000), "The more commonly grown form is related to H. nakaiana and described here."

Hosta Helper will call this plant 'Rock Princess' (Larger Type)

According to The Hosta Handbook by Mark Zilis (2000), "The other is a H. gracillima derivative and makes a smaller mound of foliage and blooms several weeks later."

Hosta Helper will call this plant 'Rock Princess' (Smaller Type)
