  A
tetraploid sport of H. 'Abba Dabba Do', this cultivar was
originated by
Tony Avent of Plant Delights Nursery in North Carolina and registered
by Hans Hansen of Minnesota in 2004.
It was given a U.S. Patent in 2006. Forms a
large size plant about 22 inch high mound which is
about 48 inches wide. The leaves are twisted, ovate and heart
shaped. Pale lavender flowers bloom from late June
into July.
According to
The Hostapedia by Mark Zilis (2009), "Plants Delight Nursery listed
this as being a
tetraploid form of 'Abba Dabba Do'."
The New Encyclopedia of Hostas by
Diana
Grenfell (2009) states: "Thrives in hotter climates...Leaves with heavier
substance and wider margins than its parent. The
eye-catching wide, even band of golden-yellow
variegation with only slight feathering into the
green base color."
The patent application lists the
following as similar cultivars: "The variegation pattern is
similar to the parent plant 'Abba Dabba
Do’, however the
margins of 'Atlantis' are significantly wider. 'Atlantis' has a similar leaf variegation pattern to 'Satisfaction' (unpatented) and H. montana ‘Aureo
Marginata'. In comparison to 'Atlantis’,
the leaves of 'Satisfaction' are broader, more
heart-shaped, and lack the terminal twist at the leaf
apex. 'Aureo
Marginata' differs from 'Atlantis' in having a more mounded, less
upright plant habit, leaf blades that curve more
downward and leaf blades that lack the twist at the
apex."
