Abstract

A new and distinct cultivar of Phlox plant named ‘Duephowi’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit; freely flowering habit; and large white-colored flowers.

Description

Botanical designation: Phlox maculata.
Cultivar denomination: ‘DUEPHOWI’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Phlox plant, botanically known as Phlox maculata and hereinafter referred to by the name ‘Duephowi’.
The new Phlox plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new compact Phlox plants with unique and attractive flower color.
The new Phlox plant originated from an open-pollination in Rheinberg, Germany in July, 2006 of a proprietary selection of Phlox maculata identified as code number PH-05-0110-001, not patented, as the female, or seed, parent with an unknown selection of Phlox maculata as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2009.
Asexual reproduction of the new Phlox plant by cuttings in a controlled environment in Rheinberg, Germany since May, 2009 has shown that the unique features of this new Phlox plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Phlox plant have not been observed under all possible environmental and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duephowi’. These characteristics in combination distinguish ‘Duephowi’ as a new and distinct Phlox plant:
    • 1. Compact, upright and outwardly spreading plant habit.
    • 2. Freely branching habit.
    • 3. Freely flowering habit.
    • 4. Large white-colored flowers.
Plants of the new Phlox can be compared to plants of the female parent selection. Plants of the new Phlox differ primarily from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Phlox are more compact than plants of the female parent selection.
    • 2. Plants of the new Phlox are more freely branching than plants of the female parent selection.
    • 3. Plants of the new Phlox and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.
Plants of the new Phlox can be compared to plants of the Phlox ‘PowerPhlox White Improved’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘PowerPhlox White Improved’ differed in the following characteristics:
    • 1. Plants of the new Phlox were more compact than plants of ‘PowerPhlox White Improved’.
    • 2. Plants of the new Phlox had larger flowers than plants of ‘PowerPhlox White Improved’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Phlox plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Phlox plant. The photograph is a close-up view of a typical flowering plant of ‘Duephowi’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown during the summer in 10.5-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under commercial practice. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Plants were pinched one time three weeks after planting and were 13 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
