There is an image of this
cultivar on the
Hosta Library. From the photo on the HL website, it appears to be a
size hosta with dark green, heart shape leaves and white medial
(center) variegation. The pattern on the variegation
shows white tissue between the green colored veins.
Hosta Library speculates that this plant is infected
with a virus.
