This is a plant that at one time was thought to be a naturally
occurring variety of the species
H. crispula. It was then
re-designated as a cultivar. 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.
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."
