There is an image of this cultivar on the Hosta Library. From the photos, it appears to be a medium size hosta with light yellow foliage that develops a yellow marginal variegation that changes to green during the season. It is a sport of H. 'Piedmont Gold'. Forms near white flowers from late June into July on nearly 3 feet long scapes. It sets viable seeds.  This is part of the Goldbrook Series from Sandra Bond of Goldbrook Plants in England.

There is also a cultivar named H. 'Goodness Gracious'.
