Description

Botanical designation: Phlox subulata.

Cultivar denomination: ‘DOPHLOSPRIBL’.

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 Aug. 12, 2020, application number 2020/1896. 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 exemption 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 subulata and hereinafter referred to by the name ‘Dophlospribl’.

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 freely-flowering Phlox plants with large attractive flowers.

The new Phlox plant originated from a cross-pollination made by the Inventor in April, 2010 in Aalsmeer, The Netherlands, of an unnamed proprietary selection of Phlox subulata, not patented, as the female, or seed, parent with an unnamed proprietary selection of Phlox subulata, not patented, as the male, or pollen, parent. The new Phlox plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Aalsmeer, The Netherlands in April, 2011.

Asexual reproduction of the new Phlox plant by vegetative cuttings in a controlled environment in Aalsmeer, The Netherlands since June, 2011 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 ‘Dophlospribl’. These characteristics in combination distinguish ‘Dophlospribl’ as a new and distinct Phlox plant:

- 1. Outwardly spreading to creeping and mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely flowering habit.
- 4. Large light violet-colored flowers with deep violet-colored centers.
- 5. Good garden performance.

Plants of the new Phlox differ primarily from plants of the parent selections in plant and flowering habit as plants of the new Phlox are more uniform and more freely flowering than plants of the parent selections.

Plants of the new Phlox can be compared to plants of Phlox subulata ‘Coral Eyes’, not patented. In side-by-side comparisons, plants of the new Phlox and ‘Coral Eyes’ differ in the following characteristics:

- 1. Plants of the new Phlox flower later than plants of ‘Coral Eyes’.
- 2. Plants of the new Phlox and ‘Coral Eyes’ differ in flower color as plants of the new Phlox have light violet-colored flowers with deep violet-colored centers whereas plants of ‘Coral Eyes’ have pink-colored flowers with dark pink-colored centers.

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 ‘Dophlospribl’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown during the spring 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 two weeks after planting rooted young plants and plants were 45 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.
