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 ‘Balbeemav’. The plants were approximately 5.5 months old. The plants were grown three plants per pot in 1.7 gallon containers for approximately 3 months in an outdoor nursery in West Chicago, Ill. Plants were given two pinches prior to transplant and one pinch one week after transplant.

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

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

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 July 2021 under natural light conditions in Naperville, Ill.

(6) The following descriptions and measurements describe approximately 5.5-month-old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown three plants per pot in 1.7 gallon containers for approximately 3 months in an outdoor nursery in West Chicago, Ill. Plants were given two pinches prior to transplant and one pinch one week after transplant. Prior to transplant plants were grown in liners in a poly-covered greenhouse in West Chicago, Ill. Greenhouse temperatures ranged from an average high of 79.5° F. (26.4° C.) to an average low of 68.5° F. (20.3° C.), and supplemental lighting was provided daily for five hours during short days. Measurements and numerical values represent averages of typical plant. Botanical classification: Monarda didyma ‘Balbeemav’.
