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 wavy, lanceolate, green leaves and a
very wide, yellow medial
(center) variegation. It is a seedling of H. 'Atom Smasher' ×
H. 'Hi Ho Silver' and bears lavender colored
flowers. This non-registered cultivar was
