A new and distinct cultivar of Phlox plant named ‘Dophloflawa’, characterized by its upright and uniform plant habit; moderately vigorous growth habit and moderate growth rate; freely branching habit; early and freely flowering habit; large red-colored flowers with reddish purple-colored centers; and good container and garden performance.

Description

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘DOPHLOFLAWA’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR & APPLICANT/ASSIGNEE

An European Community Plant Breeder's Rights application for the instant plant was filed by the Applicant/Assignee, Dümmen Group B.V. of De Lier, The Netherlands on Oct. 21, 2021, application number 2021/2620. Foreign priority is not claimed to this application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

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 ‘Dophloflawa’.

The new Phlox plant 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 early and freely-flowering Phlox plants with attractive flower color.

The new Phlox plant originated from an open-pollination in July, 2014 of a proprietary selection of Phlox paniculata identified as code number PA13-000032-002, not patented, as the female, or seed, parent with an unknown selection of Phlox paniculata 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 environment in Aalsmeer, The Netherlands in July, 2015

Asexual reproduction of the new Phlox plant by vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since March, 2016 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 have not been observed under all possible combinations of environmental conditions and cultural practices. 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 ‘Dophloflawa’. These characteristics in combination distinguish ‘Dophloflawa’ as a new and distinct Phlox plant:

- 1. Upright and uniform plant habit.
- 2. Moderately vigorous growth habit and moderate growth rate.
- 3. Freely branching habit.
- 4. Early and freely flowering habit.
- 5. Large red-colored flowers with reddish purple-colored centers.
- 6. Good container and garden performance.

Plants of the new Phlox differ from plants of the female parent selection primarily in flower color as petal lobes of plants of the new Phlox have red-colored flowers with reddish purple-colored centers whereas plants of the female parent selection have red-colored flowers with pink-colored centers.

Plants of the new Phlox can be compared to plants of Phlox paniculata ‘Sweet Summer Candy’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Sweet Summer Candy’ differ in the following characteristics:

- 1. Plants of the new Phlox have smaller flowers than plants of ‘Sweet Summer Candy’.
- 2. Plants of the new Phlox have red-colored flowers with reddish purple-colored centers whereas plants of ‘Sweet Summer Candy’ have pink-colored flowers.

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 comprises a side perspective view of typical flowering plant of ‘Dophloflawa’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the early summer in 17-cm containers initially in a glass-covered greenhouse and finished in an outdoor nursery in Aalsmeer, The Netherlands and under cultural practices typical of commercial Phlox production. During the production of the plants, day temperatures averaged 21° C. and night temperatures averaged 15° C. Plants were pinched one time one week after planting rooted young plants and were 29 weeks old when the photograph and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Second Edition, except where general terms of ordinary dictionary significance are used.
