There is an image of this
cultivar on the
Hosta Library. From the photo on the HL website, it appears to be a large
size hosta with green leaves and a creamy yellow medial
(center) variegation. This non-registered cultivar was
and Greenhouse in Georgia.
We could not find anything on a nursery of this name but
there is a Sunny Hill Greenhouses & Nursery in Georgia.
