Welcome! Pretty hosta, but I don't know off hand just what it is.
I would suggest watching it carefully next season. Take pictures of it throughout the season. Note how large it is (many hostas can look very similar but vary in size. However, in a picture w/o a size reference, it can be hard to tell). Note when it blooms and the colour of the flower. Note anything particular such as coloured flower scapes or petioles. And note whether it stays the same colour from the time it emerges - many hostas change colour a month or two later. When you get all that information, we'll be in a much better position to make and educated guess as to its ID.
