BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the name ‘Staviski Orange’.

The new Chrysanthemum is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘Staviski Pink’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘Staviski Pink’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2007.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2008. Asexual reproduction by cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Chrysanthemum have 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 ‘Staviski Orange’. These characteristics in combination distinguish ‘Staviski Orange’ as a new and distinct Chrysanthemum cultivar:

- 1. Compact, upright, outwardly spreading and rounded plant habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Uniform and freely flowering habit.
- 4. Decorative-type inflorescences with orange-colored ray florets.

Plants of the new Chrysanthemum differ primarily from the parent, ‘Staviski Pink’, in ray floret color as plants of ‘Staviski Pink’ have light pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘Staviski Dark Pink’, disclosed in U.S. Plant patent application Ser. No. 12/653,947, and Chrysanthemum×morifolium ‘Staviski White’, disclosed in U.S. Plant patent application Ser. No. 12/653,755. Plants of the new Chrysanthemum differ primarily from plants of ‘Staviski Dark Pink’ and ‘Staviski White’ in ray floret color.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Domenico Orange’, not patented. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Domenico Orange’ in the following characteristics:

- 1. Plants of the new Chrysanthemum had lighter green-colored leaves than plants of ‘Domenico Orange’.
- 2. Plants of the new Chrysanthemum flowered later than plants of ‘Domenico Orange’.
- 3. Plants of the new Chrysanthemum had smaller inflorescences than plants of ‘Domenico Orange’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant. This photograph shows 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 Chrysanthemum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Staviski Orange’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium during the summer and autumn under conditions and practices which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged from 25° C. to 30° C. and night temperatures ranged from 15° C. to 20° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2005 Edition, except where general terms of ordinary dictionary significance are used.
