Originated by Kenji Watanabe of Japan and registered on his behalf by Registrar, Kevin Walek in 2009, this fast growing cultivar is a seedling of H. pycnophylla × H. pycnophylla.

This large size plant grows to around 20 inches in height with a spread of 47 inches with medium green foliage. Its leaves are slightly wavy, ovate and have "cherry" red petioles.

'Kinba' bears clusters of purple, bell-shape flowers from mid-August into September on arching scapes 21 inches tall followed by viable seeds "depending on the weather".

The registration materials state: "...emerges golden yellow and upright changing to medium green as season progresses."

Mikiko Lockwood in an article on The Hosta Library titled, A Little About Japanese Hosta Terms defines the term kinba or kimba as yellow leaf.
