Title: Chrysanthemum Plant Named ‘G24MAG14RE’

U.S. patent application Ser. No. 19/006,053

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium, typically grown as a garden Chrysanthemum and hereinafter referred to by the name ‘G24MAG11OR’.

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 inflorescence form and ray floret coloration.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum x morifolium ‘G22MAG13BR’, disclosed in U.S. Plant Pat. No. 33,666. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘G22MAG13BR’ grown in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September 2022.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in March 2023. 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 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 ‘G24MAG11OR’. These characteristics in combination distinguish ‘G24MAG11OR’ 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; flexible stems.
- 3. Medium green-colored leaves.
- 4. Uniform and freely flowering habit.
- 5. Long flowering period.
- 6. Decorative-type inflorescences with ray florets that are reddish orange in color.
- 7. Excellent garden performance.

Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘G22MAG13BR’. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘G22MAG13BR’ in ray floret color as inflorescences of the new Chrysanthemum have reddish orange-colored ray florets whereas inflorescences of plants of ‘G22MAG13BR’ have reddish bronze-colored ray florets. In addition, plants of the new Chrysanthemum are stronger and more vigorous than plants of ‘G22MAG13BR’.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum x morifolium, ‘G24MAG14RE’, disclosed in a U.S. Plant Patent application filed concurrently. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘G24MAG14RE’ in ray floret color as inflorescences of the new Chrysanthemum have reddish orange-colored ray florets whereas inflorescences of plants of ‘G24MAG14RE’ have dark red-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum x morifolium ‘Magnus Violet’, disclosed in U.S. Plant Pat. No. 23,964. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Magnus Violet’ in ray floret color as inflorescences of plants of the new Chrysanthemum have reddish orange-colored ray florets whereas inflorescences of plants of ‘Magnus Violet’ have purple-colored ray florets.

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 ‘G24MAG11OR’ 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 under natural daylengths and employing cultural practices typically used in commercial garden 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 the detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
