Abstract

A new and distinct cultivar of Dendranthema plant named ‘Fireworks Igloo’, characterized by its upright, outwardly spreading and uniformly mounded plant habit; freely branching habit; dense and full plant form; uniform and freely flowering habit; decorative-type inflorescences; lavender-colored ray florets; and good garden performance and winter hardiness.

Description

Botanical designation: Chrysanthemum×morifolium.
Cultivar denomination: ‘FIREWORKS IGLOO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Dendranthema plant, botanically known as Chrysanthemum×morifolium, commercially grown as a perennial garden-type Dendranthema plant, and hereinafter referred to by the cultivar name ‘Fireworks Igloo’.
The objective of the breeding program is to create new perennial garden-type Dendranthema plants having uniformly mounding plant habit, inflorescences with desirable inflorescence forms, attractive floret colors and good winter hardiness and garden performance.
The new Dendranthema plant originated from a cross-pollination made by the Inventor in September, 2007, in Bogota, Colombia of a proprietary selection of Chrysanthemum×morifolium identified as code number H7486, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number H7527, not patented, as the male, or pollen, parent. The new Dendranthema plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Alva, Fla. on Oct. 30, 2008.
Asexual reproduction of the new Dendranthema plant by vegetative cuttings was first conducted in a controlled greenhouse environment in Alva, Fla. in January, 2008 and such asexual propagation has shown that the unique features of this new Dendranthema plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Dendranthema 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 ‘Fireworks Igloo’. These characteristics in combination distinguish ‘Fireworks Igloo’ as a new and distinct garden-type Dendranthema plant:
    • 1. Upright, outwardly spreading and uniformly mounded plant habit.
    • 2. Freely branching habit; dense and full plant form.
    • 3. Uniform and freely flowering habit.
    • 4. Decorative-type inflorescences with quilled-shaped ray florets.
    • 5. Lavender-colored ray florets.
    • 6. Natural season flowering occurs about September 23 in the Northern Hemisphere.
    • 7. Good garden performance and winter hardiness.
In side-by-side comparisons, plants of the new Dendranthema differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Dendranthema are larger than plants of the female parent selection.
    • 2. Plants of the new Dendranthema flower about one week later than plants of the female parent selection when grown under natural season conditions.
    • 3. Plants of the new Dendranthema have larger inflorescences than plants of the female parent selection.
    • 4. Plants of the new Dendranthema and the female parent selection differ in ray floret shape and color as plants of the female parent selection have light lavender-colored ligulate-shaped ray florets.
In side-by-side comparisons, plants of the new Dendranthema differ from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Dendranthema are rounded than and not as upright as plants of the male parent selection.
    • 2. Plants of the new Dendranthema and the male parent selection differ in ray floret color as plants of the male parent selection have coral red-colored ray florets.
Plants of the new Dendranthema can be compared to plants of Chrysanthemum×morifolium ‘Yovictoria’, disclosed in U.S. Plant Pat. No. 13,799. In side-by-side comparisons, plants of the new Dendranthema differ from plants of ‘Yovictoria’ in the following characteristics:
    • 1. Plants of the new Dendranthema are more compact than plants of ‘Yovictoria’.
    • 2. Plants of the new Dendranthema have larger inflorescences than plants of ‘Yovictoria’.
    • 3. Plants of the new Dendranthema and ‘Yovictoria’ differ in ray floret shape as plants of ‘Yovictoria’ have elongated oblong-shaped ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Dendranthema showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dendranthema plant.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Fireworks Igloo’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘Fireworks Igloo’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the early autumn in 25-cm containers in an outdoor nursery in Lancaster, Pa. and under cultural practices typical of commercial garden-type Dendranthema production. During the production of the plants, day temperatures averaged 27.8° C. and night temperatures averaged 15.6° C. Plants were 19 weeks old when the photographs and description were taken.
