Abstract

A new and distinct cultivar of Begonia plant named ‘BKPBEEFR’, characterized by its upright to outwardly spreading and mounded plant habit; freely basal branching habit; dark green-colored leaves; uniform and freely flowering habit; and double flowers with tepals and tepaloids that are bright pink in color with slightly fringed margins.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘BKPBEEFR’.

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 ‘BKPBEEFR’.

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 double flowers.

The new Begonia plant originated from a cross-pollination made by the Inventor in September, 2011 of a proprietary selection of Begonia×hiemalis identified as code number 6500161, 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 April, 2012.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since August, 2012 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 ‘BKPBEEFR’. These characteristics in combination distinguish ‘BKPBEEFR’ as a new and distinct Begonia plant:

- 1. Upright to outwardly spreading and mounded plant habit.
- 2. Freely basal branching habit.
- 3. Dark green-colored leaves.
- 4. Uniform and freely flowering habit.
- 5. Double flowers with tepals and tepaloids that are bright pink in color with slightly fringed margins.

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 double flowers whereas plants of the female parent selection have single flowers.
- 2. Flower tepals and tepaloids of plants of the new Begonia are bright pink in color whereas flower tepals of plants of the female parent selection are salmon in color.

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 larger flowers than plants of the male parent selection.
- 3. Flower tepals and tepaloids of plants of the new Begonia are bright pink in color whereas flower tepals and tepaloids of plants of the male parent selection are pale pink in color.

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

- 1. Plants of the new Begonia are bushier than and not as compact as plants of ‘Berseko’.
- 2. Tepals and tepaloids of plants of the new Begonia are more fringed than tepals and tepaloids of plants of ‘Berseko’.

Plants of the new Begonia can be compared to plants of the Begonia×hiemalis ‘Elektra Pink’, disclosed in U.S. Plant Pat. No. 18,967. In side-by-side comparisons conducted in Maasdijk, The Netherlands, plants of the new Begonia differ from plants of ‘Elektra Pink’ in the following characteristics:

- 1. Plants of the new Begonia are bushier than and not as compact as plants of ‘Elektra Pink’.
- 2. Tepals and tepaloids of plants of the new Begonia are less fringed than tepals and tepaloids of plants of ‘Elektra Pink’.

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 ‘BKPBEEFR’ grown in a container.

The photograph on the second sheet are close-up views of upper and lower surfaces of typical flowers and leaves of ‘BKPBEEFR’ and at the left center of the photograph is a close-up view of typical flower buds with pedicels.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were grown in 12-cm containers during the winter in a glass-covered greenhouse in Maasdijk, The Netherlands. During the production of the plants, day temperatures ranged from 19° to 20° C., night temperatures ranged from 18° to 19° C. and light levels averaged 6,000 lux. Plants were eleven weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
