A seedling of H. 'Whoopee', this cultivar was originated by Nancy Krul of Belle Gardens and registered by Dr. Ed Elslager (both of Michigan) in 1998. The large size (20 inches high) mound of slightly wavy, faintly corrugated leaves bears lavender flowers from mid-July into August.

According to The Hostapedia by Mark Zilis (2009), "The name represents the enthusiastic spirit exuded by the late Nancy Krul."
