Description

Botanical designation: Phlox paniculata.

Cultivar denomination: ‘DOPHLEARBLUPOP’.

CROSS-REFERENCED TO CLOSELY-RELATED APPLICATION

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. 15, 2022, application number 2022/1928. Foreign priority is not claimed to this application.

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 ‘Dophlearblupop’.

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, 2015 of a proprietary selection of Phlox paniculata identified as code number PA12-000223-001, 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, 2016.

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

• • 1. Upright and uniform plant habit.
  • 2. Vigorous growth habit and moderate growth rate.
  • 3. Freely branching habit.
  • 4. Early and freely flowering habit.
  • 5. Large white to light pink-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 plants of the new Phlox have white to light pink-colored flowers with reddish purple-colored centers whereas plants of the female parent selection have solid pink-colored flowers.

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

• • 1. Plants of the new Phlox flower earlier than plants of ‘Sweet Summer Ocean’.
  • 2. Plants of the new Phlox have smaller flowers than plants of ‘Sweet Summer Ocean’.
  • 3. Plants of the new Phlox have white to light pink-colored flowers with reddish purple-colored centers whereas plants of ‘Sweet Summer Ocean’ have bluish purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 on the first sheet (FIG. 1) is a side perspective view of typical flowering plant of ‘Dophlearblupop’ grown in a container.

The photograph on the second sheet (FIG. 2) are close-up views of typical leaves, flower buds and flowers of ‘Dophlearblupop’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring and early summer in 13-cm containers in an outdoor nursery in Straelen, Germany 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 16 weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
