Abstract

A new and distinct cultivar of Petunia plant named ‘Balcushite’, characterized by its white-colored flowers, dark green-colored foliage, and vigorous, mounded-spreading growth habit, is disclosed.

Description

Latin name of genus and species of plant claimed: Petunia x hybrida.
Variety denomination: ‘Balcushite’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Petunia plant botanically known as Petunia x hybrida and hereinafter referred to by the cultivar name ‘Balcushite’.
The new cultivar originated in a controlled breeding program in Arroyo Grande, Calif. during July 2015. The objective of the breeding program was the development of Petunia cultivars with single-type flowers, unique flower coloration and patterns, and vigorous, mounded-spreading growth habit.
The new Petunia cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is SUPERTUNIA White ‘KL 1117’, U.S. Plant Pat. No. 25,485, characterized by its white-colored flowers, medium green-colored foliage, and vigorous, mounding and outwardly spreading growth habit. The male (pollen) parent of the new cultivar is SUN SPUN White ‘Balspunwhi’, not patented, characterized by its white-colored flowers, dark green-colored foliage, low growth vigor and compact-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 April 2016 in a controlled environment in Arroyo Grande, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since April 2016 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.
SUMMARY OF THE INVENTION
The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcushite’ as a new and distinct cultivar of Petunia plant:
    • 1. White-colored flowers;
    • 2. Dark green-colored foliage; and
    • 3. Vigorous, mounded-spreading growth habit.
Plants of the new cultivar differ from plants of the female parent primarily in having darker green-colored foliage and larger petals with length measured from tube opening. Plants of the new cultivar differ from plants of the male parent primarily in having larger plant width and greater growth vigor.
Of the many commercially available Petunia cultivars, the most similar in comparison to the new cultivar is SUPERTUNIA VISTA Silverberry ‘USTUNI60-01M’ U.S. Plant Pat. No. 20,903. However, in side-by-side comparisons, plants of the new cultivar differ from plants of ‘USTUNI60-01M’ in at least the following characteristics:
    • 1. Plants of the new cultivar have a green-colored petal venation that is different from the red-purple colored petal venation in plants of ‘USTUNI60-01M’; and
    • 2. Plants of the new cultivar have larger diameter corollas than plants of ‘USTUNI60-01M’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
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 ‘Balcushite’. The plants were approximately 3.5 months old and grown in 6-inch pots for approximately 10 weeks in a greenhouse in West Chicago, Ill. Plants were given one pinch at transplant.
FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘Balcushite’.
FIG. 2 illustrates a close-up view of an individual flower of ‘Balcushite’.
DETAILED BOTANICAL DESCRIPTION
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 2019 under natural light conditions in West Chicago, Ill.
The following descriptions and measurements describe approximately 3.5-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 West Chicago, Ill. in 6-inch pots for approximately 10 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 67° F. to 72° F. (19° C. to 22° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Supplemental lighting was used. Measurements and numerical values represent averages of typical plants.
