Abstract: A new and distinct cultivar of Phlox plant named `Elisabeth`, characterized by its upright plant growth habit; green and pale yellow variegated leaves; freely flowering habit; and light red purple-colored flowers.
Claim: It is claimed:

1. A new and distinct cultivar of Phlox plant named `Elisabeth`, as illustrated and described.
Description: Botanicalclassification/cultivar designation: Phlox paniculata cultivar Elisabeth.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox paniculata, and hereinafter referred to by the name `Elisabeth`.

The new Phlox is a naturally-occurring whole plant mutation of an unidentified selection of Phlox paniculata, not patented. The new Phlox was discovered by the Inventor in a controlled environment in Vinhega, The Netherlands, within a populationof plants of the unidentified selection in 1997. The new Phlox was selected on the basis of its variegated foliage and pink-colored flowers.

Asexual reproduction of the new cultivar by vegetative cuttings taken at Vinhega, The Netherlands since February, 1998, has shown that the unique features of this new Phlox are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Elisabeth have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance ingenotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Elisabeth`. These characteristics in combination distinguish `Elisabeth` as a new and distinct cultivar: 1. Upright plant growth habit. 2. Green and pale yellow variegated leaves. 3. Freely flowering habit. 4. Light red purple-colored flowers.

Plants of the new Phlox are most similar to plants of the parent selection. In side-by-side comparisons conducted in Vinhega, The Netherlands, plants of the new Phlox differed from plants of the parent selection in the following characteristics:1. Plants of the new Phlox had variegated foliage whereas plants of the parent selection had solid green-colored foliage. 2. Plants of the new Phlox and the parent selection differed in flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of `Elisabeth` grown in a container.

The photograph at the top of the second sheet is a close-up view of typical flowers of `Elisabeth`.

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

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
