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 light green leaves and dark lavender
flowers. This non-registered cultivar was
originated in Japan.
Mikiko Lockwood in an article on The Hosta Library titled,
A Little About Japanese Hosta Terms defines the term moegi
as light (yellowish) green or lime green and the term fukurin as margined or edged.
