Abstract: A new cultivar of Hosta named `Rainbow's End`, a sport of Hosta `Obsession`, that is characterized by its unique variegated foliage with dark green margins comprising about one third of the leaf area and centers that emerge yellow green and turn creamy white. `Rainbow's End` is a medium sized Hosta with a mounded plant habit and pale violet flowers held above the foliage in late summer.
Claim: I claim:

1. A new and distinct cultivar of Hosta plant named `Rainbow's End` as herein illustrated and described.
Description: Botanicalclassification: Hosta hybrida.

Cultivar designation: `Rainbow's End`.

BACKGROUND OF THE INVENTION

The present invention, Hosta `Rainbow's End`, relates to a new and distinct cultivar of Hosta, botanically known as a Hosta hybrida, hereinafter referred to as `Rainbow's End`.

The inventor discovered the new cultivar, `Rainbow's End`, in summer of 2000 in a tissue culture lab in Waseca, Minn. `Rainbow's End` originated as a naturally occurring sport of Hosta `Obsession` (unpatented). `Rainbow's End` is unique inhaving variegated foliage with dark green margins and creamy white centers. The parent plant `Obession` is variegated with dark green margins and medium green centers.

Asexual reproduction of the new cultivar was first accomplished by the inventor 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 `Rainbow's End` are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed in trials in Minnesota for a period of five years and represent the characteristics of the new cultivar. These attributes in combination distinguish `Rainbow's End` as a new and unique cultivarof Hosta. 1. The foliage of `Rainbow's End` is variegated with dark green margins and centers that emerge yellow-green and mature to creamy white, margin width comprises on average about one third of the leaf area. The foliage of the parent plant,`Obsession`, has dark green margins and medium green centers and variegation that is much less pronounced than that of `Rainbow's End`. 2. `Rainbow's End` is a medium sized Hosta with a mounded plant habit, reaching a height of about 28 cm (exclusiveof flower scapes) and a spread of about 53 cm in six years. 3. `Rainbow's End` blooms in late summer with pale violet flowers that arise above the foliage from mid to late August in Minnesota.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta. The photographs in the figures were taken in July of mature plants of `Rainbow's End` and `Obsession` as grown outdoors inWaseca, Minn. under the same conditions for five years.

FIG. 1 provides an overall view of the plant habit and the foliage of the new cultivar, `Rainbow's End`.

FIG. 2 provides a comparison of leaves of `Rainbow's End`; a leaf of newly emerging foliage (spring foliage) on the left and a leaf of mature foliage (summer foliage) on the right.

FIG. 3 provides a comparison between a leaf of `Rainbow's End` (shown on right) and `Obsession` (shown on left).

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 five 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.
