Abstract

A new and distinct cultivar of Phlox plant named ‘Bartwentynine’, characterized by its upright and compact plant habit; freely branching growth habit; white-colored flowers; freely flowering habit; and good garden performance.

Description

Bontanical designation: Phlox paniculata.
Cultivar denomination: ‘Bartwentynine’.
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 cultivar name Bartwentynine.
The new Phlox is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to create new compact pot-type Phlox cultivars with numerous flowers with attractive leaf and flower coloration.
The new Phlox originated from a cross-pollination made by the Inventor in Aalsmeer, The Netherlands of two unnamed selections of Phlox paniculata, not patented. The new Phlox was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands.
Asexual reproduction of the new cultivar by terminal cuttings in Aalsmeer, The Netherlands, 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 Bartwentynine have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, daylength, and fertility level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bartwentynine’. These characteristics in combination distinguish ‘Bartwentynine’ as a new and distinct cultivar:
    • 1. Upright and compact plant habit.
    • 2. Freely branching growth habit.
    • 3. White-colored flowers.
    • 4. Freely flowering habit.
    • 5. Good garden performance.
Plants of the new Phlox differ from plants of the female and male parent selections in flower coloration. In addition, plants of the new Phlox are more compact than plants of the male parent selection.
Plants of the new Phlox can be compared to plants of the Phlox paniculata cultivar Barten, disclosed in U.S. Plant Pat. No. 11,802. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Phlox differed from plants of the cultivar Barten primarily in flower color as plants of the cultivar Barten had lavender-colored flowers.
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 slightly from the color values cited in the detailed botanical description which more accurately describe the actual colors of the new Phlox.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bartwentynine’ grown in a container.
The photograph on the second sheet is a close-up view of typical flowers of ‘Bartwentynine’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown in Aalsmeer, The Netherlands, in a glass-covered greenhouse and under commercial production practices during the summer. Plants were about three months old when the photographs and description were taken. During the production of the plants, day temperatures ranged from 18 to 28° C. and night temperatures ranged from 10 to 18° C. 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.
