Description

Botanical designation: Begonia x hiemalis.

Cultivar denomination: ‘DOBEGMOTWOHOPI’.

STATEMENT REGARDING PRIOR DISCLOSURES BY INVENTOR and APPLICANT/ASSIGNEE

The Inventor and Applicant/Assignee assert that no sales, offers for sale or public distribution of the instant plant 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 disclosures 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 Begonia plant, botanically known as Begonia x hiemalis, commercially referred to as an Elatior Begonia and hereinafter referred to by the name ‘Dobegmotwohopi’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the breeding program was to develop new freely flowering Begonia plants with strong branches and large double-type flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor during the autumn of 2018 of a proprietary selection of Begonia x hiemalis identified as code number BG15-000801-001, not patented, as the female, or seed, parent with a proprietary selection of Begonia x hiemalis identified as code number BG-1463, not patented, as the male or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in De Lier, The Netherlands during the spring of 2019.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in De Lier, The Netherlands since the autumn of 2019 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment 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 ‘Dobegmotwohopi’. These characteristics in combination distinguish ‘Dobegmotwohopi’ as a new and distinct Begonia plant:

• • 1. Relatively compact, upright and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Strong branching habit.
  • 4. Dark green-colored leaves.
  • 5. Freely and continuously flowering habit.
  • 6. Medium to large double-type flowers that are vivid purplish pink in color.

Plants of the new Begonia can be compared to plants of the female parent selection. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

• • 1. Leaves of plants of the new Begonia are dark green in color whereas leaves of plants of the female parent selection are dark brown in color.
  • 2. Leaves of plants of the new Begonia are glossier than leaves of plants of the female parent selection.
  • 3. Flowers of plants of the new Begonia are vivid purplish pink in color whereas flowers of plants of the female parent selection are soft orange/salmon in color.

Plants of the new Begonia can be compared to plants of the male parent selection. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Begonia are more freely branching than plants of the male parent selection.
  • 2. Leaves of plants of the new Begonia are darker green in color than leaves of plants of the male parent selection.
  • 3. Plants of the new Begonia have larger flowers than plants of the male parent selection.
  • 4. Flowers of plants of the new Begonia are vivid purplish pink in color whereas flowers of plants of the male parent selection are peachy pink in color.

Plants of the new Begonia can be compared to plants of Begonia x hiemalis ‘Dobegmotwosal’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Begonia differ primarily from plants of ‘Dobegmotwosal’ in the following characteristics:

• • 1. Plants of the new Begonia have smaller leaves than plants of ‘Dobegmotwosal’.
  • 2. Flowers of plants of the new Begonia are vivid purplish pink in color whereas flowers of plants of ‘Dobegmotwosal’ are salmon pink in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

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

The photograph is a side perspective view of a typical flowering plant of ‘Dobegmotwohopi’ grown in a container.
