This cultivar is a seedling of H. sieboldii 'Naugoku' which was registered by Ran Lydell of Cooks Nursery and Eagle Bay Gardens in New York in 2000. The small size hosta grows to about 9 inches in height with a spread of around 30 inches with medium to dark green foliage. Deep purple flowers in clusters bloom from late September into October.
