This is a tissue culture sport from 'June' and is quite unusual in its shape. I've found it slow growing, though it seems to be doing better in its latest location. It was new to me in 2010. Like most hostas in this family it held up well with very little slug damage right to the end of the season. Mine did not bloom in 2015. Please feel free to post your own pictures of this hosta.
