Abstract

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

Description

Botanical designation: Begonia×hiemalis.
Cultivar denomination: ‘ELEKTRA WHITE’.
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 ‘Elektra White’.
The new Begonia is a naturally-occurring whole plant mutation of the Begonia×hiemalis cultivar Elektra Pink, disclosed in U.S. Plant Pat. No. 18,967. 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 environment in Ermelo, The Netherlands or Jun. 9, 2004.
Asexual reproduction of the new Begonia by cuttings taken in a controlled environment in Ermelo, the Netherlands since November, 2004, 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 Elektra White 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 ‘Elektra White’. These characteristics in combination distinguish ‘Elektra White’ as a new and distinct Begonia:
    • 1. Upright and mounded plant habit.
    • 2. Freely branching habit.
    • 3. Double flowers that are white 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 Elektra Pink, in flower color as plants of the cultivar Elektra Pink have dark pink-colored flowers.
Plants of the new Begonia can also be compared to plants of the cultivar White Netja, not patented. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed from plants of the cultivar White Netja in the following characteristics:
    • 1. Plants of the new Begonia had narrower leaves than plants of the cultivar White Netja.
    • 2. Flowers of plants of the new Begonia were more double than flowers of plants of the cultivar White Netja
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 at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Elektra White’ grown in a container.
The photograph at the bottom of the sheet is a close up view of lower (left) and upper (right) surfaces of typical leaves and flowers of ‘Elektra White’.
 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 spring and summer. Average day and night temperatures were about 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 12-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 twelve weeks from planting when the photographs and description were taken.
  • Botanical classification: Begonia×hiemalis cultivar Elektra White.
  • Commercial classification: Elatior Begonia.
  • Parentage: Naturally-occurring whole plant mutation of the Begonia×hiemalis cultivar Elektra Pink, disclosed in U.S. Plant Pat. No. 18,967.
