A few months ago I posted and said the tag said it will grow 5 feet tall with a 3 ft spread, we all discussed it and so
I replanted it elsewhere in case it grows large, anyway here it is now, not really grown a lot but did bloom, thought the
flowers would be purple not white, but I like them.

Hostas always take a few years to get to their full size. After that, they become monsters. Personally, I've found that I like the white flowers on various hostas. Most of them are a pure white and are larger than purple flowers. I think yours looks perfect where it's at. If the empty space is a bit too much for your taste, you could add some pretty annuals until the hosta grows to full size.
