There is an image of this cultivar on the Hosta Library. From the photo on the HL website, it appears to be a medium to large size hosta with yellow-green leaves and yellow medial (center) variegation with pale lavender flowers on tall scapes. It is a hybrid of H. 'Xanadu Xanthippe'.  This non-registered cultivar was originated by Virginia and Brian Skaggs of Indiana.
