plant named ‘BKBEWFAFSP’

Abstract

A new and distinct cultivar of Begonia plant named ‘BKBEWFAFSP’, characterized by its upright, outwardly spreading to pendulous plant habit; moderately freely basal branching habit; medium-size leaves; freely and continuously flowering habit; flowers that are light pink in color with darker pink-colored margins; long flowering period; and good garden performance.

Description

Botanical designation: Begonia pendula.

Cultivar denomination: ‘BKBEWFAFSP’.

BACKGROUND OF THE INVENTION

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

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 hanging basket Begonia plants with good summer performance and long flowering period.

The new Begonia plant originated from a cross-pollination made by the Inventor in March, 2007 of a proprietary selection of Begonia pendula identified as code number 07-002-04, not patented, as the female, or seed, parent with a proprietary selection of Begonia pendula identified as code number 06-276-08, 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 April, 2008.

Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Amstelveen, The Netherlands since May, 2009 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 ‘BKBEWFAFSP’. These characteristics in combination distinguish ‘BKBEWFAFSP’ as a new and distinct Begonia plant:

• • 1. Upright, outwardly spreading to pendulous plant habit.
  • 2. Moderately freely basal branching habit.
  • 3. Medium-size leaves.
  • 4. Freely and continuously flowering habit.
  • 5. Flowers that are light pink in color with darker pink-colored margins.
  • 6. Long flowering period; plants flower throughout the summer in The Netherlands.

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 have darker green-colored leaves than plants of the female parent selection.
  • 2. Leaves of plants of the new Begonia are slightly pubescent whereas leaves of plants of the female parent selection are glabrous.
  • 3. Plants of the new Begonia and the female parent selection differ in flower color as plants of the female parent selection have pale orange-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 flower color as plants of the male parent selection have white-colored flowers.

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

• • 1. Plants of the new Begonia had semi-double type flowers whereas plants of ‘Rainbow Falls’ had double type flowers.
  • 2. Plants of the new Begonia and ‘Rainbow Falls’ differed in flower color as plants of ‘Rainbow Falls’ had yellow and pink-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia ‘BKBEWPF’, disclosed in U.S. Plant Pat. No. 23,138. In side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Begonia differed from plants of ‘BKBEWPF’ in the following characteristics:

• • 1. Plants of the new Begonia were more compact than plants of ‘BKBEWPF’.
  • 2. Flowers of plants of the new Begonia had fewer tepaloids than flowers of plants of ‘BKBEWPF’.
