There is an image of this
cultivar on the
Hosta Library. From the photo on the HL website, it appears to be a small
size hosta with dark green leaves and a patterned creamy
(center) variegation. It is a sport of H.
'Thunderbolt' and bears near white flowers from mid-June
into July. This slow growing, non-registered cultivar was
Dr. Ullrich Fischer of Germany.
