Description

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

(1) 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 may differ slightly from the color values cited in the detailed description, which accurately describes the colors of Balcabros20. The plants were approximately 8 months old and grown in 3-gallon containers in an outdoor nursery environment in West Chicago, Ill. for approximately 5 months. Treatments are described below in the Detailed Botanical Description.

(2) FIG. 1 illustrates a side view of the overall growth and flowering habit of Balcabros20.

(3) FIG. 2 illustrates a close-up view of an individual flower of Balcabros20.

DETAILED BOTANICAL DESCRIPTION

(4) 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.

(5) 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 October 2018 under natural light conditions in West Chicago, Ill.

(6) The following descriptions and measurements describe plants produced from cuttings from stock under conditions comparable to those used in commercial practice. The plants were approximately 8 months old and grown in 3-gallon containers in an outdoor nursery environment in West Chicago, Ill. for approximately 5 months. Plants were given two pinches, the first at 3 weeks after cuttings were stuck and a second approximately 3 weeks later. Plants were treated with plant growth regulators of Daminozide at 2500 ppm and Chlormequat chloride at 750 ppm approximately 4 weeks after cuttings were stuck. Measurements and numerical values represent averages of typical plants. Botanical classification: Calibrachoa x hybrida Balcabros20.
