Latin name of genus and species of plant claimed: Buddleja hybrid.
Variety denomination: ‘Balchryink’.BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Buddleja plant botanically known as Buddleja hybrid and hereinafter referred to by the cultivar name ‘Balchryink’.
The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during the summer of 2018. The objective of the breeding program was the development of Buddleja cultivars having numerous inflorescences with distinctive coloration, repeat blooming, and a highly branched, compact-mounded growth habit.
The new Buddleja cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is Buzz Hot Raspberry ‘Tobud1202’, U.S. Plant Patent applied for, characterized by its deep, red-purple colored flowers having an orange center, medium green colored foliage, and moderately vigorous, compact-mounded growth habit. The male (pollen) parent of the new cultivar is unknown. The new cultivar was selected as a single flowering plant within the progeny of the above stated open-pollination during April 2019 in a controlled environment in Guadalupe, Calif.
Asexual reproduction of the new cultivar by terminal stem cuttings since April 2019 in Guadalupe, 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 ‘Balchryink’ as a new and distinct cultivar of Buddleja plant:
- 1. Light purplish-pink colored flowers;
- 2. Dark 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 in having light purplish-pink colored flowers and reduced growth vigor.
Of the many commercially available Buddleja cultivars, the most similar in comparison to the new cultivar is Buzz Purple ‘Tobudpipur’, U.S. Plant Pat. No. 22,064. However, in comparison, plants of the new cultivar differ from plants of ‘Tobudpipur’ in at least the following characteristics:
- 1. Plants of the new cultivar have smaller diameter corollas than plants of ‘Tobudpipur’; and
- 2. Plants of the new cultivar have lighter, purplish-pink colored flowers than plants of ‘Tobudpipur’.
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 ‘Balchryink’. The plants were approximately five-months old. The plants were grown for approximately 9 weeks in three-quart containers in an outdoor nursery in West Chicago, Ill. Plants were given two pinches prior to transplant and one pinch one week after transplant.
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 July 2021 under natural light conditions in Naperville, Ill.
The following descriptions and measurements describe approximately five-month-old plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown in three-quart containers for approximately 9 weeks 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 plants.
