Description

Latin name of genus and species of plant claimed: Phlox paniculata.

Variety denomination: ‘Balkapopur’.

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 ‘Balkapopur’.

The new cultivar originated in a controlled breeding program in Hem, the Netherlands during August 2013. The objective of the breeding program was the development of Phlox cultivars with attractive flower coloration, increased powdery mildew resistance and a compact growth habit.

The new Phlox cultivar is the result of open-pollination within an insect-cage environment. The female (seed) parent of the new cultivar is the proprietary Phlox paniculata breeding selection coded D05, not patented, characterized by its medium purple-colored flowers, medium green-colored foliage, and moderately vigorous, compact-upright growth habit. The male (pollen) parent of the new cultivar is one of four proprietary Phlox paniculata breeding selections, not coded, not patented, characterized by having different shades of purple-colored flowers, medium green-colored foliage, and moderately vigorous, highly-branched, upright growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during July 2014 in a controlled environment in Hem, the Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings since July 2014 in Hem, the Netherlands and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balkapopur’ as a new and distinct cultivar of Phlox plant:

    • 1. Medium purple-colored flowers;
    • 2. Medium green-colored foliage; and
    • 3. Moderately vigorous, compact-upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a different shade of flower color and increased branching. Plants of the new cultivar differ from plants of the potential male parents primarily in having a different shade of flower color.

Of the many commercially available Phlox cultivars, the most similar in comparison to the new cultivar is Flame Purple ‘Barfourteen’, U.S. Plant Pat. No. 12,605. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Barfourteen’ in at least the following characteristics:

    • 1. Plants of the new cultivar have a flower color that has more purple than plants of ‘Barfourteen’;
    • 2. Plants of the new cultivar are shorter than plants of ‘Barfourteen’; and
    • 3. Plants of the new cultivar have larger diameter flowers than plants of ‘Barfourteen’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balkapopur’. The plants were approximately four months old. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balkapopur’.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘Balkapopur’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2018 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe approximately four-month old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in one-gallon containers for approximately 11 weeks in a greenhouse in Elburn, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant. Greenhouse temperatures were maintained at approximately 65° F. to 70° F. (18.3° C. to 21.1° C.) during the day and approximately 55° F. to 60° F. (12.8° C. to 15.6° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
