This non-registered cultivar is a white margined sport of H. 'Snow Mound' that was found by
Summers of Delaware in the late 1960s. It grows into a medium size (11 inches high) mound and puts on pure white flowers in August.
The Hostapedia by Mark Zilis (2009), "With a better name, this plant would have seem much
greater popularity. It offers an attractive show of white
flowers in August over a dense mound of white-edged foliage."
Similar cultivars include H. 'Carrie Ann' and H. 'Louisa'.
