plant named ‘Balgerpur103’

Latin name of genus and species of plant claimed:interspecific.

Variety denomination: ‘Balgerpur103’.

The present invention relates to a new and distinct cultivar ofplant botanically known asinterspecific and hereinafter referred to by the cultivar name ‘Balgerpur103’.

The new cultivar originated in a controlled breeding program in Hem, the Netherlands during August 2018. The objective of the breeding program was the development ofcultivars that flower uniformly and have large flowers, dark, green-colored foliage, and a vigorous, low-mounded growth habit.

The newcultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is proprietarybreeding selection coded 2018-019, not patented, characterized by its single, pink-colored flowers, medium, green-colored foliage, and moderately vigorous, spreading growth habit. The male (pollen) parent of the new cultivar is‘Baby Blue’, not patented, characterized by its single, lavender-blue colored flowers, medium, green-colored foliage, vigorous, semi-upright growth habit. The new cultivar was selected as a single flowering plant within the progeny of the above stated cross-pollination during August 2019 in a controlled environment in Hem, the Netherlands.

Asexual reproduction of the new cultivar by terminal stem cuttings since August 2019 in Hem, the Netherlands and West Chicago, Illinois, has demonstrated that the new cultivar reproduces true to type with all the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balgerpur103’ as a new and distinct cultivar ofplant:

Plants of the new cultivar differ from plants of the female parent primarily by having a mounded growth habit and longer flowering period. Plants of the new cultivar differ from plants of the male parent primarily by having a mounding habit and purple-violet-colored flowers.

Of the many commercially availablecultivars, the most similar in comparison to the new cultivar isinterspecific ‘Rozanne’, U.S. Plant Pat. No. 12,175. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘Rozanne’ in at least the following characteristics:

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 April 2025 under natural light conditions in West Chicago, Illinois.

The following descriptions and measurements describe approximately nine-month-old plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in 3-quart containers for approximately six months in a double polyethylene greenhouse in Elburn, Illinois. Greenhouse temperatures were maintained at approximately 42° F. to 47° F. (5.6° C. to 8.3° C.) during the day and approximately 37° F. to 42° F. (2.8° C. to 5.0° C.) during the night. No supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
