Originated in Japan but registered in 2005 by Peter and Jean Ruh of Ohio and re-registered with new data in 2018, this slow growing cultivar is a seedling of H. 'Yakushima Mizu'. It is a miniature size hosta that grows to only 3 inches in height with a spread of around 7 inches.

The medium green foliage has a yellow marginal variegation which changes to white later in the season. Its leaves are deeply wavy, lanceolate, slightly cupped, slightly twisted and slightly shiny on top with short petioles. Lavender flowers with white edges bloom on 9 inch tall scapes from mid-August into September on scapes up to 9 inches tall.

According to the registration materials: "...flat growth, white edges, miniature...margin begins yellow, turns white..."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term mizu as water, 'Mizu Gibōshi' or H. longissima and the term fukurin as margined or edged.
