Abstract: A distinct cultivar of Hosta plant named `Paradise Joyce`, characterized by its variegated leaf color; relatively compact plant habit; and light lavender-colored flowers that are positioned above the foliage on strong and erect scapes.
Claim: It is claimed:

1. A new and distinct cultivar of Hosta plant named `Paradise Joyce`, as illustrated and described.

The present Invention relates to a new and distinct cultivar of Hosta plant, botanically known as Hosta hybrid, and hereinafter referred to by the culitvar name Paradise Joyce.

The new Hosta was discovered by the Inventor in a controlled environment in Ter Aar, The Netherlands, as a whole plant mutation of the Hosta hybrid cultivar Halcyon, not patented, in 1993. Plants of the cultivar Halcyon have solidblue-green-colored leaves whereas plants of the new Hosta have variegated leaves.

Asexual reproduction of the new cultivar by divisions harvested in Ter Aar, The Netherlands, has shown that the unique features of this new Hosta are stable and reproduced true to type in successive generations.


Plants of the cultivar Paradise Joyce have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, irrigation amount andfrequency, and/or fertilizer rate without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Paradise Joyce`. These characteristics in combination distinguish `Paradise Joyce` as a new and distinct cultivar:

1. Variegated leaf color.

2. Relatively compact plant habit.

3. Light lavender-colored flowers that are positioned above the foliage on strong and erect scapes.

Plants of the new Hosta can be compared to plants of the variegated Hosta hybrid June, not patented. Compared to plants of the new Hosta, plants of the cultivar June have darker and duller leaf colors.


The accompanying colored photographs illustrate the overall appearance of the new Hosta, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly fromthe color values cited in the detailed botanical description which more accurately describe the actual colors of the new Hosta.

The photograph on the first sheet comprises a side perspective view of typical flowering plants of `Paradise Joyce` grown in containers.

The photograph at the top of the second sheet is a close-up view of typcal flowers of `Paradise Joyce`.

The photograph at the bottom of the second sheet is a close-up view of the upper surface of a typical leaf of `Paradise Joyce`.


In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Plants used for the following description were about 40 weeks oldand grown in 17-cm containers under field conditions which closely approximate commercial production conditions during the spring and summer in Ter Aar, The Netherlands.
