A sport of H. 'Choo Choo Train',
this cultivar was registered by
Shady Oaks Nursery of Minnesota in 2004 and granted a U.S. patent in 2005. The green
foliage is heavily rippled and has a gold marginal variegation. It
is a large size (22 inches high by 62 inches wide) plant that bears pale lavender flowers in July
followed by viable seeds.
The Hostapedia by Mark Zilis (2009), "Its heavily rippled character accentuates the contrast
between the medium green center and gold margin."
The New Encyclopedia of Hostas by
Grenfell (2009) states: "Good growth rate. A superb specimen plant...The
leaf emerges golden yellow, the green center appears
gradually after a few weeks."
The patent application lists the
following as similar cultivars: "The closest comparison plant is 'Journey's End’, a sibling
of 'American Icon’, which differs in having leaves with
the reverse variegation pattern to 'American Icon’;
yellow green centers and green margins. 'American Icon' can also be compared to 'Satisfaction' (not patented), a
plant of similar stature and leaf variegation pattern. 'Satisfaction' is a chimeral mutation of golden foliaged 'Piedmont Gold' (not patented). 'Satisfaction' differs
from 'American Icon' in having less ruffled leaf margins
and by emerging earlier in the spring resulting in
susceptibility to frost damage, particularly in the
Southern regions of the U.S."
United States Patent: PP17441 (2007)
