BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘G20ARL11OR’.
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 withy unique and attractive ray floret coloration.
The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum X morifolium ‘Arluno Pink’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a single plant from within a population of plants of ‘Arluno Pink’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2015.
Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2016. 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
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G20ARL11OR’. These characteristics in combination distinguish ‘G20ARL11OR’ as a new and distinct Chrysanthemum plant:
- 1. Upright, outwardly spreading and uniformly rounded plant habit; moderately vigorous growth habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Dark green-colored leaves.
- 4. Uniform and freely flowering habit.
- 5. Long flowering period.
- 6. Decorative-type inflorescences with ray florets that are greyed red in color.
Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘Arluno Pink’. Plants of the new Chrysanthemum differ primarily from plants of ‘Arluno Pink’ in the following characteristics:
- 1. Plants of the new Chrysanthemum are more uniform than plants of ‘Arluno Pink’.
- 2. Ray florets of plants of the new Chrysanthemum are greyed red in color whereas ray florets of plants of ‘Arluno Pink’ are light red purple in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘Arluno Dark Pink’, disclosed in U.S. Plant patent application Ser. No. 15/732,901. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Arluno Dark Pink’ in ray floret color as ray florets of plants of the new Chrysanthemum are greyed red in color whereas ray florets of plants of ‘Arluno Dark Pink’ are light red purple in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘GED18ARL2Y’, disclosed in U.S. Plant patent application Ser. No. 15/732,906. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘GED18ARL2Y’ in ray floret color as ray florets of plants of the new Chrysanthemum are greyed red in color whereas ray florets of plants of ‘GED18ARL2Y’ are bright yellow in color.
Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum X morifolium ‘GED18ARL6V’, disclosed in U.S. Plant patent application Ser. No. 15/732,907. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘GED18ARL6V’ in ray floret color as ray florets of plants of the new Chrysanthemum are greyed red in color whereas ray florets of plants of ‘GED18ARL6V’ are dark red purple in color.
Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘Amiko Bronze’, disclosed in U.S. Plant Pat. No. 24,201. In side by side comparison, plants of the new Chrysanthemum differ primarily from plants of ‘Amiko Bronze’ in the following characteristics:
- 1. Plants of the new Chrysanthemum are more uniformly rounded than plants of ‘Amiko Bronze’.
- 2. Leaves of plants of the new Chrysanthemum are darker green in color than leaves of plants of ‘Amiko Bronze’.
- 3. Plants of the new Chrysanthemum flower about one week later than plants of ‘Amiko Bronze’.
- 4. Plants of the new Chrysanthemum have slightly smaller inflorescences than plants of ‘Amiko Bronze’.
- 5. Ray florets of plants of the new Chrysanthemum are greyed red in color whereas ray florets of plants of ‘Amiko Bronze’ are greyed orange in color.
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. The photograph comprises a side perspective view of a typical flowering plant of ‘G20ARL11OR’ 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 cultural practices generally used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007, Fifth Edition, except where general terms of ordinary dictionary significance are used.
