This is a plant that at one time was thought to be a naturally occurring botanical variety of the species H. crispula. It was then re-designated as a cultivar status probably because of lack of evidence that it came from the wild. The plant forms a large size mound whose foliage is medium green in color and slightly rippled. It bears very pale lavender flowers in July.

According to The Hostapedia by Mark Zilis (2009), "...is certainly the equal of many other large-size green-leaved cultivars. It makes an excellent background plant or large ground cover."

"An all-green form of the species, but the leaf margin is not as undulate. Aoba in Aoba Sazanami Gibōshi means green leaf, and the name indicates that a green-leaved form also exists in Japan. Maekawa considered H. kiyosumiensis to be very closely related to H. 'Crispula' but the latter has a taller scape and a much higher flower count."
