I've only got about 50 hosta, so this is the first time I have seen this. The oddball hosta is just so varied from the main plant, makes me wonder what happened here. Are sports sometimes totally different?

Yes they are usually quite different. The next question would be is it a stable mutation? Perhaps separate it from the mother plant.

Could it be a previous plant in that spot making a comeback?

Larry it was potted until this spring, and the place I planted it previously had daylilies. My trees have really started putting out some shade.
Gary thank you, since I just planted it 6 weeks ago, I'm going to leave it and do that next spring if it comes back this way. Make a note to look for it, thank you.

Is that particular plant new to you or have you had it for awhile? They are so very different that it makes me wonder whether you somehow have two different plants mixed up together. I also would be inclined to separate the two. That might also shed light on whether you have a sport or just two plants when you see how the roots blend together.
