Abstract: A new cultivar of Hosta named `Atlantis`, a sport of Hosta `Abba Dabba Do`, that is characterized by its unique variegated foliage with green centers and wide yellow-green margins comprising about on third of the leaf area. `Atlantis` is a large Hosta with an upright, mounded habit, a vigorous growth rate, and lavender flowers held on upright scapes in mid summer.
Claim: We claim:

1. A new and distinct cultivar of Hosta plant named `Atlantis` as herein illustrated and described.
Description: Botanicalclassification: Hosta sp.

Cultivar designation: `Atlantis`.

BACKGROUND OF THE INVENTION

The present invention, Hosta `Atlantis`, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta hybrid, hereinafter referred to as `Atlantis`.

The inventors discovered the new cultivar, `Atlantis`, in summer of 1998 in a cultivated growing area in Waseca, Minn. `Atlantis` originated as a naturally occurring chimeral mutation of Hosta `Abba Dabba Do` (unpatented). The parent plant,Hosta, `Abba Dabba Do`, is a variegated mutation of the gold foliaged cultivar, Hosta `Sun Power` (unpatented). `Atlantis` is unique in having wide yellow-green margins surrounding green centers. 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` arebroader, 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.

Asexual reproduction of the new cultivar was first accomplished by the inventors utilizing in vitro propagation in Waseca, Minn. in fall of 2002. Asexual reproduction of the new cultivar by division and tissue culture has shown that the uniquefeatures of `Atlantis` are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed in trials in North Carolina and Minnesota for a period of six years and represent the characteristics of the new cultivar. These attributes in combination distinguish `Atlantis` as a new andunique cultivar of Hosta. 1. The foliage of `Atlantis` is variegated with yellow-green margins and green centers. The margins of `Atlantis` comprise about one third of the leaf area, the margins are much wider than the parent plant, `Abba Dabba Do`. 2. The plant habit of `Atlantis` is upright and mounding. 3. `Atlantis` reaches a height of about 77 cm, exclusive of flower scapes, and a spread of about 178 cm in six years. 4. `Atlantis` has large leaves with undulating margins with a twist atthe leaf apex. 5. `Atlantis` blooms in mid summer with pale lavender flowers that arise above the foliage.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs were taken of mature plants of `Atlantis` and `Abba Dabba Do` as grown outdoor in Waseca, Minn. under the sameconditions for six years.

FIG. 1 was taken in June and provides an overall view of the foliage and plant habit of the new cultivar, `Atlantis`.

The photograph in FIG. 2 was taken in August and provides a comparison between a leaf of `Atlantis` (shown on left) and `Abba Dabba Do` (shown on right) as grown in light shade.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and combined with the color values cited in the detailed botanical description accurately describe the colors of the new Hosta.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 6 year-old plants of the new cultivar as grown outdoors in Waseca, Minn. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has notbeen tested under all possible environmental conditions. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionarysignificance are used. Botanical classification: `Atlantis` is a cultivar of Hosta of hybrid origin. Parentage: Naturally occurring chimeral mutation of Hosta `Abba Dabba Do` (not patented). General description: Blooming period.--About 3 to 4 weeksfrom early July to early August. Plant habit.--Herbaceous perennial, clump-forming, upright and mounded foliage of large size.
