Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘STAVISKI YELLOW’.

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 Yellow’.

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 October, 2008.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2009. 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 and cultural 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 Yellow’. These characteristics in combination distinguish ‘Staviski Yellow’ as a new and distinct Chrysanthemum plant:

    • 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. Small decorative-type inflorescences with yellow-colored ray florets.
    • 5. Excellent garden performance.

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 also be compared to plants of Chrysanthemum×morifolium ‘PPP TER Y05’, disclosed in U.S. Plant Pat. No. 16,959. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘PPP TER Y05’ in the following characteristics:

    • 1. Plants of the new Chrysanthemum were more rounded and uniform than and not as upright and open as plants of ‘PPP TER Y05’.
    • 2. Plants of the new Chrysanthemum were not as brittle as plants of ‘PPP TER Y05’.
    • 3. Inflorescences of plants of the new Chrysanthemum were smaller than inflorescences of plants of ‘PPP TER Y05’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant 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 Chrysanthemum plant.

The photograph comprises a side perspective view of a typical flowering plant of ‘Staviski Yellow’ 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 and under conditions and practices which approximate those generally used in commercial Chrysanthemum 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.
