Abstract

A new and distinct cultivar of Begonia plant named ‘Bbtosca’, characterized by its medium-sized, upright and mounded plant habit; double flowers with orange-colored tepals; and excellent flower longevity.

Description

Botanical designation: Begonia×hiemalis.
Cultivar denomination: ‘Bbtosca’.
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 ‘Bbtosca’.
The new Begonia was discovered and selected by the Inventor in a controlled environment in Odense, Denmark in April, 1999, as a naturally-occurring whole plant mutation of Begonia×hiemalis ‘Batik’, not patented. The new Begonia was observed as a single plant in a group of flowering plants of the parent cultivar.
Asexual reproduction of the new Begonia by cuttings in a controlled environment in Odense, Denmark since 2000, 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 ‘Bbtosca’ 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 ‘Bbtosca’. These characteristics in combination distinguish ‘Bbtosca’ as a new and distinct Begonia:
    • 1. Medium-sized, upright and mounded plant habit.
    • 2. Double flowers with orange-colored tepals.
    • 3. Excellent flower longevity.
Plants of the new Begonia can be compared to plants of the parent, the cultivar Batik. Plants of the new Begonia differ primarily from plants of the cultivar Batik in the following characteristics:
    • 1. Plants of the new Begonia are more vigorous than plants of the cultivar Batik.
    • 2. Plants of the new Begonia have more tepals per flower than plants of the cultivar Batik.
    • 3. Plants of the new Begonia and the cultivar Batik differ in tepal color as plants of the cultivar Batik have orange red-colored tepals.
Plants of the new Begonia can also be compared to plants of the cultivar Bente, not patented. However flower color of plants of the new Begonia is lighter orange than flower color of plants of the cultivar Bente.
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 ‘Bbtosca’.
The photograph on the second sheet is a close-up view of a typical flower of ‘Bbtosca’.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photograph and following observations and measurements describe plants grown in Aalsmeer, The Netherlands during the spring and summer, and grown under conditions typical of commercial practice in a glass-covered greenhouse. During the production of the plants, day and night temperatures ranged from 15 to 20° C. and light levels were about 18,000 lux. Plants used for the photograph and the description were grown in 13-cm containers and were about three months old when the photograph and description were taken.
  • Botanical classification: Begonia×hiemalis cultivar Bbtosca.
  • Commercial classification: Elatior Begonia.
  • Parentage: Naturally-occurring whole plant mutation of Begonia×hiemalis cultivar Batik, not patented.

  • Flower description:
      • Flowering habit.—Double flowers with about 10 to 20 tepals per flower; flowers arranged in axillary cymes; about five to six open flowers per cyme; numerous cymes in flower simultaneously; about 25 to 30 open flowers per plant. Flowers positioned above and beyond the foliage and face upright to outwardly. Flowers not fragrant.
      • Natural flowering season.—Under natural daylight conditions, plants flower from spring until the fall. Flower initiation and development is induced by long day/short night conditions. Flowering continuous under photoinductive conditions.
