Botanical designation: Osteospermum ecklonis.
Cultivar denomination: ‘Sunny Christian’.
BACKGROUND OF THE INVENTIONThe present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Sunny Christian’.
The new Osteospermum is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the program is to create and develop new Osteospermum cultivars with compact and uniformly mounded plant habit, freely flowering habit and attractive inflorescence coloration.
The new Osteospermum originated from a cross-pollination by the Inventor in May, 2004 of a proprietary selection of Osteospermum ecklonis identified as code number 10.501.02, not patented, as the female, or seed, parent with the Osteospermum ecklonis cultivar Sunny Serena, disclosed in U.S. Plant Pat. No. 15,693, as the male, or pollen, parent. The new Osteospermum was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Odense, Denmark in June, 2005.
Asexual reproduction of the new Osteospermum by terminal cuttings in a controlled environment in Odense, Denmark since January, 2007, has shown that the unique features of this new Osteospermum are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe cultivar Sunny Christian 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 ‘Sunny Christian’. These characteristics in combination distinguish ‘Sunny Christian’ as a new and distinct cultivar of Osteospermum:
-
- 1. Compact and mounded plant habit.
- 2. Freely branching growth habit.
- 3. Freely flowering habit.
- 4. Daisy-type inflorescences with oblanceolate-shaped ray florets that are blush white in color with light brown and brown-striped lower surfaces.
- 5. Good garden performance.
Plants of the new Osteospermum differ from plants of the female parent selection in the following characteristics:
-
- 1. Upper surfaces of ray florets of plants of the new Osteospermum are blush white in color whereas upper surfaces of ray florets of plants of the female parent selection are white in color.
- 2. Lower surfaces of ray florets of plants of the new Osteospermum are light brown and brown-striped whereas lower surfaces of ray florets of plants of the female parent selection are bright yellow in color.
Plants of the new Osteospermum differ from plants of the male parent, the cultivar Sunny Serena, in the following characteristics:
-
- 1. Upper surfaces of ray florets of plants of the new Osteospermum are blush white in color whereas upper surfaces of ray florets of plants of the cultivar Sunny Serena are salmon in color.
- 2. Lower surfaces of ray florets of plants of the new Osteospermum are light brown and brown-striped whereas lower surfaces of ray florets of plants of the cultivar Sunny Serena are brownish salmon in color.
Plants of the new Osteospermum can be compared to plants of the Osteospermum cultivar Sunny Henry, disclosed in U.S. Plant Pat. No. 16,251. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of the cultivar Sunny Henry primarily in the lower surface color of the ray florets as lower surfaces of ray florets of plants of the cultivar Sunny Henry were bright yellow in color. In addition, plants of the new Osteospermum had larger inflorescences than plants of the cultivar Sunny Henry.
The accompanying photographs illustrate the overall appearance of the new Osteospermum. This photographs shows 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 Osteospermum.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunny Christian’.
The photograph at the bottom of the sheet is a close-up view of a typical inflorescence of ‘Sunny Christian’.
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, following observations and measurements describe plants grown in Odense, Denmark during the spring in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 14° C. to 20° C., night temperatures averaged 14° C. and light levels ranged from 200 to 800 watts per square meter. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were about 15 weeks old when the photographs and description were taken.
