Bob Solberg of Green Hill Farm in North Carolina registered this sport
of his H. 'Ginsu Knife' in 2002. It forms a
large size clump about 19
inches high by 3 feet wide. The leaves are narrowly ovate in
shape and have a twisted, curved tip. Whitish, slightly fragrant
flowers are borne in July.
The Hostapedia by Mark Zilis (2009), "...possess irregular ripples and tiny serrations on
relatively narrow, large leaves. As a clump it's anything but
neat and formal, but I think that adds to its allure."
