BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially referred to as Elatior Begonia and hereinafter referred to by the name ‘BKPBECRM’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program was to develop new freely branching and freely flowering Begonia plants with attractive flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in March, 2013 of a proprietary selection of Begonia×hiemalis identified as code number 6900484, not patented, as the female, or seed, parent with a proprietary selection of Begonia×hiemalis identified as code number 6500604, 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 Maasdijk, The Netherlands in November, 2013.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since February, 2014 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 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 ‘BKPBECRM’. These characteristics in combination distinguish ‘BKPBECRM’ as a new and distinct Begonia plant:

- 1. Broadly upright to outwardly spreading and mounded plant habit.
- 2. Sturdy plants with freely basal branching habit.
- 3. Dark green-colored leaves.
- 4. Uniform and freely flowering habit.
- 5. Single-type female flowers and fully double male flowers that are dark red in color.

Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

- 1. Plants of the new Begonia and the female parent selection differ in leaf texture as plants of the female parent selection have pubescent leaves.
- 2. Plants of the new Begonia and the female parent selection differ in flower color as plants of the female parent selection have orange yellow-colored flowers.

Plants of the new Begonia can be compared to plants of the male parent selection. Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

- 1. Plants of the new Begonia and the male parent selection differ in flower form as plants of the male parent selection only have single-type flowers.
- 2. Plants of the new Begonia and the male parent selection differ in flower color as plants of the male parent selection have pale pink-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia×hiemalis ‘BKPBECLR’, disclosed in a U.S. Plant patent application Ser. No. 14/999,404 filed concurrently. Plants of the new Begonia differ from plants of ‘BKPBECLR’ in the following characteristics:

- 1. Plants of the new Begonia are shorter than plants of ‘BKPBECLR’.
- 2. Plants of the new Begonia and ‘BKPBECLR’ differ in leaf color as plants of ‘BKPBECLR’ have very dark-colored leaves.
- 3. Male flowers of plants of the new Begonia have more tepaloids than male flowers of plants of ‘BKPBECLR’.

Plants of the new Begonia can also be compared to plants of the Begonia×hiemalis ‘Baladin’, not patented. In side-by-side comparisons, plants of the new Begonia differ from plants of ‘Baladin’ in the following characteristics:

- 1. Plants of the new Begonia are more vigorous than plants of ‘Baladin’.
- 2. Plants of the new Begonia are more freely branching than plants of ‘Baladin’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘BKPBECRM’ grown in a container.

The photograph on the second sheet are close-up views of upper and lower surfaces of typical fully developed male flowers and leaves of ‘BKPBECRM’.
