plant named ‘Dardoran Imp’

Abstract

A new and distinct cultivar of Begonia plant named ‘Dardoran Imp’ characterized by its compact, upright, outwardly spreading and mounded plant habit; freely branching habit; dark green-colored leaves; numerous orange-colored double flowers that are held above and beyond the foliar plane; and excellent postproduction longevity.

Description

Botanical designation: Begonia×hiemalis.

Cultivar denomination: ‘DARDORAN IMP’.

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 ‘Dardoran Imp’.

The new Begonia plant is a naturally-occurring whole plant mutation of Begonia×hiemalis ‘Dardoran’, not patented. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Dardoran’ in a controlled greenhouse environment in Ermelo, The Netherlands in July, 2008.

Asexual reproduction of the new Begonia plant by vegetative cuttings taken in a controlled greenhouse environment in Ermelo, The Netherlands since November, 2008 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 and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Dardoran Imp’. These characteristics in combination distinguish ‘Dardoran Imp’ as a new and distinct Begonia plant:

• • 1. Compact, upright, outwardly spreading and mounded plant habit.
  • 2. Freely branching habit.
  • 3. Dark green-colored leaves.
  • 4. Numerous orange-colored double flowers that are held above and beyond the foliar plane.
  • 5. Excellent postproduction longevity.

Plants of the new Begonia differ primarily from plants of the parent, ‘Dardoran’, in flower color. Plants of the new Begonia have darker orange-colored flowers than plants of ‘Dardoran’.

Plants of the new Begonia can be compared to plants of Begonia×hiemalis ‘Reina’, disclosed in U.S. Plant Pat. No. 19,336. In side-by-side comparisons conducted in Ermelo, The Netherlands, plants of the new Begonia differed primarily from plants of ‘Reina’ in flower color and form as plants of ‘Reina’ had slightly darker orange-colored flowers with fewer tepaloids.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate 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 photographs 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 on the first sheet comprises a side perspective view of a typical flowering plant of ‘Dardoran Imp’ grown in a container.

The photograph on the second sheet are close up views of the upper and lower surfaces of typical leaves (right) and upper, lateral and lower surfaces of developing and open flowers of ‘Dardoran Imp’ (left).

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 13-cm containers in a glass-covered greenhouse in Ermelo, The Netherlands and under cultural practices typical of commercial Begonia production. During the production of the plants, day temperatures averaged 20° C. and night temperatures averaged 18° C. Plants were pinched one time and were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
