Latin name of genus and species of plant claimed: Calibrachoa hybrida.
Variety denomination: ‘Balcongarlu’.
The present invention relates to a new and distinct cultivar of Calibrachoa plant botanically known as Calibrachoa hybrida and hereinafter referred to by the cultivar name ‘Balcongarlu’.
The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during March 2014. The objective of the breeding program was the development of Calibrachoa cultivars with unique flower coloration and compact, mounded growth habit.
The new Calibrachoa cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Calibrachoa hybrida breeding selection coded PN10110-1, not patented, characterized by its medium pink-colored flowers, medium green-colored foliage, low growth vigor, and compact-mounded growth habit. The male (pollen) parent of the new cultivar is the proprietary Calibrachoa hybrida breeding selection coded PN10645-2, not patented, characterized by its medium purple-colored flowers, medium green-colored foliage, and moderately vigorous, mounded growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during August 2014 in a controlled environment in Arroyo Grande, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since August 2014 in Arroyo Grande, Calif. and West Chicago, 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.
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcongarlu’ as a new and distinct cultivar of Calibrachoa plant:
-
- 1. Medium violet-colored flowers;
- 2. Medium green-colored foliage;
- 3. Low growth vigor; and
- 4. Compact-mounded growth habit.
Plants of the new cultivar differ from plants of the female parent primarily in flower color. Plants of the new cultivar differ from plants of the male parent primarily in having a compact growth habit.
Of the many commercially available Calibrachoa cultivars, the most similar in comparison to the new cultivar is CALIPETITE Blue ‘SAKCAL106’, not patented, U.S. Plant patent application Ser. No. 13/815,966 now abandoned. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘SAKCAL106’ in at least the following characteristics:
-
- 1. Plants of the new cultivar are taller than plants of ‘SAKCAL106’;
- 2. Plants of the new cultivar have flowers with a darker-colored throat opening than ‘SAKCAL106’; and
- 3. Plants of the new cultivar have narrower leaves than plants of ‘SAKCAL106’.
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 ‘Balcongarlu’. The plants were grown in 4.5-inch pots for 9 weeks in a greenhouse in West Chicago, Ill. Plants were given one pinch one week after transplant.
FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balcongarlu’.
FIG. 2 illustrates a close-up view of an individual flower of ‘Balcongarlu’.
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 February 2017 under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe 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 West Chicago, Ill. in 4.5-inch pots for 9 weeks utilizing a soilless growth medium. Plants were given one pinch one week after transplant. Greenhouse temperatures were maintained at approximately 66° F. to 70° F. (19° C. to 21° C.) during the day and approximately 58° F. to 62° F. (14° C. to 17° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
