Dr. Kevin Vaughn of Massachusetts, this non-registered cultivar is a sport of H. 'Formal
Attire'. This large size (26 inches high), has green
foliage with a white medial (center) variegation and
produces pale lavender flowers in mid-August.
The Hostapedia by Mark Zilis (2009), "...presumably white-centered, green-margined foliage...may no longer exist."
