This is a green leaved,
tissue culture sport of H. 'Masquerade' that was introduced by
Mark Zilis of Illinois and Q&Z Nursery in 2003. It forms a medium size (11 inches high)
mound and displays deep purple flowers from late June into July.
The Hostapedia by Mark Zilis (2009), this cultivar "...makes a much
better garden plant than the white-centered 'Masquerade'. It can
be used as a low ground cover or edger. Much to my surprise, it
also exhibits good sun tolerance."
Similar cultivars include H. 'Alpine Dream', H. 'Pearl
Buttons' and H. 'Venessa'.
Q&Z Nursery closed in the fall of 2014.
An article by Warren I. Pollock in
Hosta Journal (2009 Vol. 40 No. 1) states that, "It
turns out the green sport of 'Masquerade' was registered twice and with two
different names. In 1999
Van Wade...registered this sport as 'Vanessa'...Mark Zilis...informed me that he registered it as 'Munchkin' in 2003."
