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 a Elatior Begonia and hereinafter referred to by the name ‘BKPBECSA’.

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

The new Begonia plant originated from a cross-pollination made by the Inventor in September, 2006 of a proprietary selection of Begonia hiemalis identified as code number 06-289-03, 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 Amstelveen, The Netherlands in October, 2007.

Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Amstelveen, The Netherlands since February, 2008 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 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 ‘BKPBECSA’. These characteristics in combination distinguish ‘BKPBECSA’ as a new and distinct Begonia plant:

• • 1. Broadly upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Moderately freely basal branching habit.
  • 3. Medium-size leaves.
  • 4. Uniform and freely flowering habit.
  • 5. Flowers that are salmon pink in color on both the upper and lower surfaces.

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 primarily in the following characteristics:

• • 1. Leaves of plants of the new Begonia are lighter green in color than leaves of plants of the female parent selection.
  • 2. Leaves of plants of the new Begonia are glabrous whereas leaves of plants of the female parent selection are slightly pubescent.
  • 3. Plants of the new Begonia and the female parent selection differ in flower color as plants of the female parent selection have 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 have darker green-colored leaves than plants of the male parent selection.
  • 2. Plants of the new Begonia have double type flowers whereas plants of the male parent selection have single type flowers.
  • 3. Plants of the new Begonia have larger flowers than plants of the male parent selection.

Plants of the new Begonia can be compared to plants of the Begonia ‘BKPBEELA’, disclosed in U.S. Plant Patent application Ser. No. 13/507,634. Plants of the new Begonia and ‘BKPBEELA’ differ primarily in the following characteristics:

• • 1. Plants of the new Begonia flower about five days later than plants of ‘BKPBEELA’.
  • 2. Plants of the new Begonia are not as freely flowering as plants of ‘BKPBEELA’.

Plants of the new Begonia can also be compared to plants of the Begonia ‘Ceveca’, not patented. In side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Begonia differed from plants of ‘Ceveca’ in the following characteristics:

• • 1. Plants of the new Begonia were not as compact as plants of ‘Ceveca’.
  • 2. Plants of the new Begonia had lighter-colored leaves than plants of ‘Ceveca’.
  • 3. Plants of the new Begonia and ‘Ceveca’ differed in flower color as plants of ‘Ceveca’ had bright pink-colored flowers.
