I did a little research on your mutant hosta and found a couple of pictures you might want to look over.

Sometimes hostas are classified as plantain lilies - and after a search I found a couple that had similar leaf stalks to yours... Maybe this information will lead you in the right direction.

Here is a link that might be useful: Francee Plantain lily

They are one in the same. I have seen hostas that do that, but they usually start out with normal leaves from the bottom, then shoot up, I'm not sure why.
