There is an image of this
cultivar on the
Hosta Library. From the (low quality) photo, it appears to be a large
size hosta with dark blue-green leaves and some leaves
have creamy yellow to white streaked variegation. This non-registered cultivar was
Wade of Wade and Gatton Nursery (Closed 2019) of Ohio.
by the single photo on the website, it is not apparent
as to how this plant gets its name. All the leaf edges
on that plant are blue-green...or, at least that's how
they look to me.
