Description

Botanical designation: Begonia hiemalis.

Cultivar denomination: ‘LYDIA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia hiemalis, commercially referred to as a Elatior Begonia and hereinafter referred to by the name ‘LYDIA’.

The new Begonia plant is a naturally-occurring whole plant mutation of Begonia hiemalis ‘Nadine’, disclosed in U.S. Plant patent application Ser. No. 10/008,292 (abandoned). The new Begonia plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘Nadine’ in a controlled greenhouse environment in Heinenoord, The Netherlands in March, 2010.

Asexual reproduction of the new Begonia plant by tip cuttings in a controlled greenhouse environment in Amstelveen, The Netherlands since February, 2011 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 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 ‘LYDIA’. These characteristics in combination distinguish ‘LYDIA’ as a new and distinct Begonia plant:

    • 1. Upright, somewhat outwardly spreading and mounded plant habit.
    • 2. Basal branching habit.
    • 3. Dark green-colored leaves.
    • 4. Uniform and freely flowering habit.
    • 5. Double flowers that are yellow and orange in color.

Plants of the new Begonia can be compared to plants of the mutation parent, ‘Nadine’. Plants of the new Begonia differ primarily from plants of ‘Nadine’ in the following characteristics:

    • 1. Plants of the new Begonia are more compact and denser than plants of ‘Nadine’.
    • 2. Flowers of plants of the new Begonia are double whereas flowers of plants of ‘Nadine’ are single.

Plants of the new Begonia can be compared to plants of the Begonia ‘BBEVA’, disclosed in U.S. Plant Pat. No. 16,053. In side-by-side comparisons conducted in ‘s-Gravenzande, The Netherlands, plants of the new Begonia differed from plants of ‘BBEVA’ in the following characteristics:

    • 1. Plants of the new Begonia were larger than and not as compact as plants of ‘BBEVA’.
    • 2. Flowers of plants of the new Begonia had fewer tepals than flowers of plants of ‘BBEVA’.

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 ‘LYDIA’ grown in a container.

The photograph on the second sheet are close up views of typical flower buds, flowers and leaves of ‘LYDIA’.

DETAILED BOTANICAL DESCRIPTIONS

Plants used for the aforementioned photographs and following observations and measurements were grown in 13-cm containers during the summer in a glass-covered greenhouse in ‘s-Gravenzande, The Netherlands. During the production of the plants, day temperatures ranged from 20° to 21° C., night temperatures ranged from 19° to 20° C. and light levels averaged 7,000 lux. Plants were eleven weeks old when the photographs and the 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.
