Begonia plant named `BKPBEWFER`

Abstract

A new and distinct cultivar of Begonia plant named `BKPBEWFER`, characterized by its outwardly spreading to pendulous and mounded plant habit; freely basal branching habit; freely and continuously flowering habit; long flowering period; plants flower throughout the summer in The Netherlands; and single male and female flowers that are bright red in color.

Description

Botanical designation: Begonia pendula.times.Begonia boliviensis.

Cultivar denomination: `BKPBEWFER`.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia pendula.times.Begonia boliviensis and hereinafter referred to by the name `BKPBEWFER`.

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 hanging Begonia plants with freely branching and flowering habit, good summer performance and long flowering period.

The new Begonia plant originated from a cross-pollination made by the Inventor in March, 2010 of a proprietary selection of Begonia pendula identified as code number 06-290-32, not patented, as the female, or seed, parent with a proprietary selection of Begonia boliviensis identified as code number 07-002, 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 July, 2010.

Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since October, 2010 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 `BKPBEWFER`. These characteristics in combination distinguish `BKPBEWFER` as a new and distinct Begonia plant: 1. Outwardly spreading to pendulous and mounded plant habit. 2. Freely basal branching habit. 3. Freely and continuously flowering habit. 4. Long flowering period; plants flower throughout the summer in The Netherlands. 5. Single male and female flowers that are bright 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 have single flowers whereas plants of the female parent selection have double flowers. 2. Plants of the new Begonia and the female parent selection differ in flower color as plants of the female parent selection have white-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-colored leaves than plants of the male parent selection. 2. Plants of the new Begonia and the male parent selection differ 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 Begonia pendula.times.Begonia boliviensis `Encanto Orange`, disclosed in U.S. Plant Pat. No. 20,898. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Begonia differed primarily from plants of `Encanto Orange` in the following characteristics: 1. Plants of the new Begonia had darker-colored leaves than plants of `Encanto Orange`. 2. Plants of the new Begonia and `Encanto Orange` differed in flower color as plants of `Encanto Orange` had bright orange-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia hybrid `Sunjirared`, disclosed in U.S. Plant patent application Ser. No. 13/385,537. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Begonia differed primarily from plants of `Sunjirared` in the following characteristics: 1. Plants of the new Begonia were bushier than and not as compact as plants of `Sunjirared`. 2. Flowers of plants of the new Begonia had more rounded tepal apices than flowers of plants of `Sunjirared`.
