Abstract

A new and distinct cultivar of Begonia plant named ‘BKPBEEGW’, characterized by its broadly upright, somewhat outwardly spreading and mounded plant habit; moderately freely basal branching habit; medium-size leaves; uniform and freely flowering habit; and double flowers that are white in color on both the upper and lower surfaces.

Description

Botanical designation: Begonia hiemalis.
Cultivar denomination: ‘BKPBEEGW’.
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 ‘BKPBEEGW’.
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 is a naturally-occurring branch mutation of Begonia hiemalis ‘BKPBEEGL’, disclosed in U.S. Plant Pat. No. 23,825. The new Begonia plant was discovered and selected by the Inventor on a single flowering plant within a population of plants of ‘BKPBEEGL’ in a controlled greenhouse environment in Amstelveen, The Netherlands in October, 2010.
Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Amstelveen, The Netherlands since February, 2011 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 ‘BKPBEEGW’. These characteristics in combination distinguish ‘BKPBEEGW’ 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. Double flowers that are white in color on both the upper and lower surfaces.
Plants of the new Begonia can be compared to plants of the parent, ‘BKPBEEGL’. Plants of the new Begonia differ from plants of ‘BKPBEEGL’ primarily in flower color as plants of ‘BKPBEEGL’ have pink-colored flowers. In addition, plants of the new Begonia are not as compact as plants of ‘BKPBEEGL’.
Plants of the new Begonia can be compared to plants of the Begonia ‘Bonbon White’, not patented. In side-by-side comparisons conducted in Amstelveen, The Netherlands, plants of the new Begonia differed from plants of ‘Bonbon White’ in the following characteristics:
    • 1. Plants of the new Begonia were more compact than plants of ‘Bonbon White’.
    • 2. Plants of the new Begonia and ‘Bonbon White’ differed slightly in flower color.
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 ‘BKPBEEGW’ grown in a container.
The photograph on the second sheet is a close up view of the upper and lower surfaces of typical flower buds, flowers and leaves of ‘BKPBEEGW’.
 DETAILED BOTANICAL DESCRIPTION
Plants used for the aforementioned photographs and following observations and measurements were grown in 11-cm containers during the spring in a glass-covered greenhouse in Maasdijk, The Netherlands. During the production of the plants, day temperatures ranged from 19° C. to 20° C., night temperatures ranged from 18° C. 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.
