Foreign priority is not claimed to this European Community Plant Breeder's Rights application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida and hereinafter referred to by the name ‘BKDAMOR’.

The new Dahlia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new freely branching container Dahlia plants with large inflorescences and attractive ray floret coloration.

The new Dahlia plant originated from an open-pollination in September, 2014 in Maasdijk, The Netherlands of a proprietary selection of Dahlia hybrida identified as code number 12-0032-06, as the female, or seed, parent with an unknown selection of Dahlia hybrida as the male, or pollen, parent. The new Dahlia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in December, 2014.

Asexual reproduction of the new Dahlia plant by terminal cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since March, 2016 has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Dahlia have not been observed under all possible combinations of environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BKDAMOR’. These characteristics in combination distinguish ‘BKDAMOR’ as a new and distinct Dahlia plant:

• • 1. Upright to somewhat outwardly spreading and sturdy plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense and bushy growth habit.
  • 4. Dark green-colored leaves.
  • 5. Freely flowering habit.
  • 6. Decorative type inflorescences with orange-colored ray florets.
  • 7. Good garden performance.

Plants of the new Dahlia differ primarily from plants of the female parent selection in inflorescence size as plants of the new Dahlia have slightly larger inflorescences than plants of the female parent selection. In addition, ray florets of plants of the new Dahlia are darker orange in color than ray florets of plants of the female parent selection.

Plants of the new Dahlia can be compared to plants of Dahlia hybrida ‘Baldahanni’, not patented. In side-by-side comparisons, plants of the new Dahlia differ primarily from plants of ‘Baldahanni’ in inflorescence size as plants of the new Dahlia have larger inflorescences than plants of ‘Baldahanni’. In addition, ray florets of plants of the new Dahlia are not as bright orange in color as ray florets of plants of ‘Baldahanni’.

Plants of the new Dahlia can also be compared to plants of Dahlia hybrida ‘Dahlietta Linda’, not patented. In side-by-side comparisons, plants of the new Dahlia differ primarily from plants of ‘Dahlietta Linda’ in inflorescence size as plants of the new Dahlia have larger inflorescences than plants of ‘Dahlietta Linda’. In addition, ray florets of plants of the new Dahlia are more orange than and not as yellow as ray florets of plants of ‘Dahlietta Linda’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Dahlia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia plant.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical inflorescence of ‘BKDAMOR’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and the following observations and measurements describe plants grown during the autumn and winter in 11-cm containers in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial Dahlia production. During the production of the plants, day and night temperatures ranged from 17° C. to 19° C. Plants were pinched one time and were nine weeks from planting rooted cuttings when the photographs and description were taken.
