Begonia plant named ‘Bbpaola’

Abstract

A new and distinct cultivar of Begonia plant named ‘Bbpaola’, characterized by its compact, upright and mounded plant habit; freely flowering habit; double flowers with orange to red-colored tepals; and excellent flower longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘Bbpaola’.

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 ‘Bbpaola’.

The new Begonia was discovered and selected by the Inventor in a controlled environment in Glandorf, Germany in 1999, as a naturally-occurring whole plant mutation of a proprietary seedling selection of Begonia×hiemalis identified as code number C8, not patented. The new Begonia was observed as a single plant in a group of flowering plants of the parent selection.

Asexual reproduction of the new Begonia by cuttings in a controlled environment in Glandorf, Germany 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 ‘Bbpaola’ 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 ‘Bbpaola’. These characteristics in combination distinguish ‘Bbpaola’ as a new and distinct Begonia:

• • 1. Compact, upright and mounded plant habit.
  • 2. Freely flowering habit.
  • 3. Double flowers with orange to red-colored tepals.
  • 4. Excellent flower longevity.

Compared to plants of the parent selection, plants of the new Begonia have flowers with more tepals. In addition, plants of the new Begonia and the parent selection differ in tepal coloration as plants of the parent selection have darker red-colored tepals.

Plants of the new Begonia can also be compared to plants of the cultivar Monella, disclosed in U.S. Plant Pat. No. 13,153. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Begonia differed from plants of the cultivar Monella in the following characteristics:

• • 1. Plants of the new Begonia had fewer tepals per flower than plants of the cultivar Monella.
  • 2. Plants of the new Begonia and the cultivar Monella differed in tepal coloration as plants of the cultivar Monella had red and yellow bi-colored tepals.
  • 3. Plants of the new Begonia and the cultivar Monella differed in pedicel and flower bract coloration as plants of the cultivar Monella had yellow-colored pedicels and flower bracts.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia.

The photograph comprises a side perspective view of a typical flowering plant of ‘Bbpaola’ grown in a container.

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 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.
