BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia×hiemalis, commercially known as Elatior Begonia, and hereinafter referred to by the name ‘BBDRASUN’.

The new Begonia plant is a naturally-occurring whole plant mutation of the Begonia×hiemalis cultivar BBDRA, disclosed in U.S. Plant Pat. No. 19,700. The new Begonia was discovered and selected by the Inventor from within a population of plants of ‘BBDRA’ in a controlled greenhouse environment in Rijsenhout, The Netherlands during the spring of 2007.

Asexual reproduction of the new Begonia plant by terminal cuttings in a controlled greenhouse environment in Rijsenhout, the Netherlands since the autumn of 2007, 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. The phenotype may vary somewhat with variations in cultural practices and environment 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 ‘BBDRASUN’. These characteristics in combination distinguish ‘BBDRASUN’ as a new and distinct Begonia plant:

    • 1. Upright and mounded plant habit.
    • 2. Freely branching habit.
    • 3. Numerous double flowers that are yellow and pink in color.
    • 4. Good postproduction longevity.

Plants of the new Begonia differ primarily from plants of the parent, ‘BBDRA’, primarily in flower color as plants of ‘BBDRA’ have light red-colored flowers. In addition, flower of plants of ‘BBDRA’ appear to be more “filled” than flowers of the new Begonia.

Plants of the new Begonia differ primarily from plants of Begonia×hiemalis ‘BBDRASOPI’, disclosed in a U.S. Plant patent application No. 12/807,247, and plants of Begonia×hiemalis ‘BBDRAWHIBLU’, disclosed in U.S. Plant patent application No. 12/807,246, in flower color as plants of ‘BBDRASOPI’ and pink-colored flowers and plants of ‘BBDRAWHIBLU’ have white and pink-colored flowers.

Plants of the new Begonia can be compared to plants of Begonia×hiemalis ‘BBTAM’, disclosed in U.S. Plant Pat. No. 19,800. In side-by-side comparisons conducted in Rijsenhout, The Netherlands, plants of the new Begonia differed from plants of ‘BBTAM’ primarily in flower color as plants of ‘BBTAM’ had salmon pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph 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 comprises a side perspective view of a typical flowering plant of ‘BBDRASUN’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photograph and following observations and measurements were grown during the spring and summer in 13-cm containers in a shaded glass-covered greenhouse in Rijsenhout, The Netherlands and grown under typical Begonia production practices. During the production of the plants day and night temperatures ranged from 15° C. to 20° C. and maximum light levels were 18,000 lux. Plants were twelve weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
