Begonia plant named ‘Bela Lilacpink’

Abstract

A new and distinct cultivar of Begonia plant named ‘Bela Lilacpink’, characterized by its upright and mounded plant habit; freely branching habit; double flowers that are dark pink in color and held above and beyond the foliage; and excellent postproduction longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘Bela Lilacpink’.

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 ‘Bela Lilacpink’.

The new Begonia is a naturally-occurring whole plant mutation of the Begonia×hiemalis cultivar Bela, disclosed in U.S. Plant Pat. No. 13,655. The new Begonia was discovered and selected by the Inventor as a flowering plant from within a population of plants of the parent cultivar in a controlled greenhouse environment in Ermelo, The Netherlands in April, 2005.

Asexual reproduction of the new Begonia by cuttings taken in a controlled greenhouse environment in Ermelo, the Netherlands since June, 2005, has shown that the unique features of this new Begonia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Bela Lilacpink has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength 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 ‘Bela Lilacpink’. These characteristics in combination distinguish ‘Bela Lilacpink’ as a new and distinct Begonia:

• • 1. Upright and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Double flowers that are dark pink in color and held above and beyond the foliage.
  • 4. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the parent, the cultivar Bela, in flower color as plants of the cultivar Bela have dark pinkish red-colored flowers.

Plants of the new Begonia can also be compared to plants of the cultivar Berseba, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed primarily from plants of the cultivar Berseba in flower color as plants of the cultivar Berseba had lighter pink-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia, 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.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Bela Lilacpink’ grown in a container.

The photograph on the second sheet is a close up view of upper and lower surfaces of typical leaves (left) and upper, side and lower surfaces of typical flowers (right) of ‘Bela Lilacpink’.

DETAILED BOTANICAL DESCRIPTION

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. The aforementioned photographs and following observations and measurements describe plants grown in Ermelo, The Netherlands, under commercial practice in a glass-covered greenhouse during the winter. Average day and night temperatures were 20° C. during the first three to four weeks then lowered to an average day and night temperature of 18° C. until flowering. Four weeks after planting rooted cuttings in 13-cm containers, two five-day periods of long nyctoperiods of 16 hours were given and were separated by two days and subsequently followed by short nyctoperiods of eight hours until flowering. Plants were pinched one time about one week after planting. Plants were about 14 weeks from planting when the photographs and description were taken.
