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 differ slightly from the color values cited in the detailed description, which accurately describes the colors of Balkapopink. The plants were approximately four months old. The plants were grown in one-gallon containers for approximately 12 weeks in a greenhouse in Elburn, Ill. Plants were given two pinches, one at one week before transplant and one two weeks after transplant.

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

(3) FIG. 2 illustrates a close-up view of an individual inflorescence of Balkapopink.

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 RHS 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.
