This sport of H. 'Carder Blue' was
Marc Laviana of
Sunny Border Nurseries in Connecticut and
registered by him and
Alex Malloy of New York in 2001.
Marc was granted a U.S. patent for this hosta in 2005. It grows
into a medium size hosta with a height of
about 14 inches and a spread around 35 inches. This plant
produces pale lavender flowers in late July.
The Hostapedia by Mark Zilis (2009), "I doubt that 'Grand Marquee'
sported from its listed mother plant, 'Carder Blue'. 'Grand
Marquee' bears a close resemblance to 'Olympic Sunrise' and
'Touch of Class', two sports related to 'Halcyon', and does not
appear anything like 'Carder Blue'."
United States Patent: PP15961 (2005)

Marquee’, characterized by its unique variegated foliage
