Abstract

A new and distinct cultivar of Chrysanthemum plant named ‘Pomona Purple’, characterized by its uniform, upright, outwardly spreading and rounded plant habit; moderately vigorous to vigorous growth habit; freely branching habit; dense and full plant habit; uniform and freely flowering habit; large decorative-type inflorescences with dark purple violet-colored ray florets; and excellent garden performance.

Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘POMONA PURPLE’.

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 ‘Pomona Purple’.

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 originated from a cross-pollination made by the Inventor in Oostnieuwkerke, Belgium in September, 2004 of Chrysanthemum×morifolium ‘Peacock’, not patented, as the female, or seed, parent with Chrysanthemum×morifolium ‘Movado Purple’, not patented. The new Chrysanthemum plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Oostnieuwkerke, Belgium in September, 2005.

Asexual reproduction of the new Chrysanthemum plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2006. 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 ‘Pomona Purple’. These characteristics in combination distinguish ‘Pomona Purple’ as a new and distinct Chrysanthemum plant:

- 1. Uniform, upright, outwardly spreading and rounded plant habit; moderately vigorous to vigorous growth habit.
- 2. Freely branching habit; dense and full plant habit.
- 3. Uniform and freely flowering habit.
- 4. Large decorative-type inflorescences with dark purple violet-colored ray florets.
- 5. Excellent garden performance.

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

- 1. Plants of the new Chrysanthemum are more rounded than and not as upright as plants of ‘Peacock’.
- 2. Plants of the new Chrysanthemum are flexible and not brittle like plants of ‘Peacock’.
- 3. Ray florets of plants of the new Chrysanthemum are lighter in color than ray florets of plants of ‘Peacock’.

Plants of the new Chrysanthemum differ primarily from the male parent, ‘Movado Purple’, in the following characteristics:

- 1. Plants of the new Chrysanthemum are not as vigorous as plants of ‘Movado Purple’.
- 2. Ray florets of plants of the new Chrysanthemum are lighter in color than ray florets of plants of ‘Movado Purple’.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum×morifolium ‘Megan’, disclosed in U.S. Plant Pat. No. 8,756. In side-by-side comparisons conducted in Oostnieuwkerke, Belgium, plants of the new Chrysanthemum differed from plants of ‘Megan’ in the following characteristics:

- 1. Plants of the new Chrysanthemum were more rounded than and not as upright as plants of ‘Megan’.
- 2. Plants of the new Chrysanthemum were flexible and not brittle like plants of ‘Megan’.
- 3. Plants of the new Chrysanthemum had smaller inflorescences than plants of ‘Megan’.

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 ‘Pomona Purple’ 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.
