Abstract
A new and distinct cultivar of Chrysanthemum plant named ‘Vigorelli Dark Orange’, characterized by its upright, outwardly spreading and uniformly rounded plant habit; vigorous growth habit; dark green-colored leaves; uniform and freely flowering habit; and relatively large decorative-type inflorescences with ray florets that are initially dark red in color becoming dark orange and lighter orange in color with subsequent development giving the inflorescences a bi-colored appearance.
Description
BOTANICAL DESIGNATION


Chrysanthemum×morifolium


CULTIVAR DENOMINATION ‘Vigorelli Dark Orange’
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 ‘Vigorelli Dark Orange’.


The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive ray floret coloration.


The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum×morifolium ‘Vigorelli Orange’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Vigorelli Orange’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2012.


Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2013. Asexual reproduction by vegetative terminal 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 combinations of 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 ‘Vigorelli Dark Orange’. These characteristics in combination distinguish ‘Vigorelli Dark Orange’ as a new and distinct Chrysanthemum plant:

    • 1. Upright, outwardly spreading and uniformly rounded plant habit.
    • 2. Vigorous growth habit.
    • 3. Dark green-colored leaves.
    • 4. Uniform and freely flowering habit.
    • 5. Relatively large decorative-type inflorescences with ray florets that are initially dark red in color becoming dark orange and lighter orange in color with subsequent development giving the inflorescences a bi-colored appearance.


Plants of the new Chrysanthemum differ primarily from the parent, ‘Vigorelli Orange’, in the following characteristics:

    • 1. Plants of the new Chrysanthemum are not as compact as plants of ‘Vigorelli Orange’.
    • 2. Plants of the new Chrysanthemum and ‘Vigorelli Orange’ differ in ray floret color as plants of the new Chrysanthemum have darker orange-colored ray florets than plants of ‘Vigorelli Orange’.


Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum×morifolium ‘PPP COL OR07’, disclosed in U.S. Plant Pat. No. 20,355. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘PPP COL OR07’ in the following characteristics:

    • 1. Plants of the new Chrysanthemum were smaller than plants of ‘PPP COL OR07’.
    • 2. Leaves of plants of the new Chrysanthemum were brighter green in color than leaves of plants of ‘PPP COL OR07’.
    • 3. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘PPP COL OR07’.
    • 4. Plants of the new Chrysanthemum flowered later than plants of ‘PPP COL OR07’.





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 ‘Vigorelli Dark 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 spring and summer and under cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 18° C. to 21° C. and night temperatures ranged from 10° C. to 15° C. Plants were 20 weeks old when the photograph and description were taken. In the following description, color references are made to
