Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Amiko Bronze’, characterized by its upright, outwardly spreading and rounded plant habit; freely branching habit; dense and full plant habit; uniform, early and freely flowering habit; decorative-type inflorescences with bronze-colored ray florets; and excellent garden performance.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘AMIKO BRONZE’.

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 ‘Amiko Bronze’.

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 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 ‘PPP AMIK 09’, disclosed in U.S. Plant Pat. No. 21,453. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘PPP AMIK 09’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2010.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2011. 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 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 ‘Amiko Bronze’. These characteristics in combination distinguish ‘Amiko Bronze’ as a new and distinct Chrysanthemum plant:

- 1. Upright, outwardly spreading and rounded plant habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Uniform, early and freely flowering habit.
- 4. Decorative-type inflorescences with bronze-colored ray florets.
- 5. Excellent garden performance.

Plants of the new Chrysanthemum differ primarily from the parent, ‘PPP AMIK 09’, primarily in ray floret color as plants of ‘PPP AMIK 09’ have violet-colored ray florets.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Gedi Three Pora’, disclosed in U.S. Plant Pat. No. 17,067. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Gedi Three Pora’ in the following characteristics:

- 1. Plants of the new Chrysanthemum were more compact than plants of ‘Gedi Three Pora’.
- 2. Plants of the new Chrysanthemum had lighter green-colored leaves than plants of ‘Gedi Three Pora’.
- 3. Plants of the new Chrysanthemum had larger inflorescences than plants of ‘Gedi Three Pora’.

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 ‘Amiko Bronze’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers during the late summer and early autumn in an outdoor nursery in Oostnieuwkerke, Belgium and under cultural 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 detailed 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.
