Abstract: A new cultivar of Hosta named `Paradise Island`, a sport of Hosta `Fire Island`, that is characterized by its unique variegated foliage with bright yellow to yellow- centers and dark green margins, its red petioles and red markings extending into the leaf blade and its lavender flowers present in early to mid summer.
Claim: It is claimed:

1. A new and distinct cultivar of Hosta plant named `Paradise Island` as herein illustrated and described.
Description: Botanicalclassification: Hosta hybrida.

Cultivar designation: `Paradise Island`.

BACKGROUND OF THE INVENTION

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

The Inventor discovered the new cultivar, `Paradise Island`, in a container in his nursery in August of 2003 in Ter Aar, The Netherlands. `Paradise Island` originated as a naturally occurring chimeral mutation of Hosta `Fire Island`(unpatented).

Asexual reproduction of the new cultivar was first accomplished under the direction of the Inventor utilizing in vitro propagation in Reeuwijk, The Netherlands in September of 2005. Asexual reproduction of the new cultivar by division and tissueculture has shown that the unique features of `Paradise Island` 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 `Paradise Island` as a new and uniquecultivar of Hosta. 1. `Paradise Island` exhibits foliage that is variegated with bright yellow centers and dark green margins. As the season progresses, the centers become yellow-green in color with the margins remaining dark green. 2. `ParadiseIsland` exhibits upright held red leaf petioles with the red coloration extending into the leaf blade. 3. `Paradise Island` blooms in early to mid summer with lavender flowers.

The parent plant, Hosta `Fire Island`, has foliage that non-variegated with yellow to yellow-green foliage and red petioles. The closest comparison plant is `Eye Declare`, which has similar leaf variegation and coloration but `Eye Declare`differs in having petioles and leaf blades that are green and lack the red coloration as observed with `Paradise Island`.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Hosta, `Paradise Island`. The photographs were taken of 1 year old plants as grown as grown outdoors in Ter Aar, The Netherlands.

FIG. 1 provides an overall view of the foliage and plant habit of the new cultivar.

The photograph in FIG. 2 provides a close-up view of a newly emerged leaf and petiole while the photograph in FIG. 3 provides a close-up view of a mature leaf and petiole.

The photograph in FIG. 4 provides a close-up of the new Hosta's flowers and buds.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and the color values cited in the Detailed Botanical Description most accurately describe the colors of the new Hosta.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of one year-old plants of the new cultivar as grown outdoors in Ter Aar, The Netherlands. Plants used for data collection were grown under average day temperatures of 10.degree. to 25.degree. C. andaverage night temperatures of 3.degree. to 14.degree. C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The colordetermination 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 dictionary significance are used.
