Abstract

A new and distinct cultivar of Dendranthema plant named ‘Ice Pink 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; bright red purple-colored ray florets; natural season flowering occurs about September 22 to 26 in Pennsylvania; and good garden performance and winter hardiness.

Description

Botanical designation: Chrysanthemum X morifolium.
Cultivar denomination: ‘ICE PINK IGLOO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Dendranthema plant, botanically known as Chrysanthemum X morifolium, commercially grown as a perennial garden-type Dendranthema plant, and hereinafter referred to by the cultivar name ‘Ice Pink Igloo’.
The new Dendranthema is the product of a planned breeding program conducted by the Inventor in Bogota, Colombia and Smoketown, Pa. 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 ray and disc floret shapes and colors, winter hardiness and good garden performance.
The new Dendranthema plant originated from a cross-pollination made by the Inventor in 2009 in Bogota, Colombia, of a proprietary seedling selection of Chrysanthemum X morifolium identified as code number H0695, not patented, as the female, or seed, parent with Chrysanthemum X morifolium ‘Cool Yoigloo’, disclosed in U.S. Plant Pat. No. 20,225, 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 Smoketown, Pa. on Sep. 25, 2013.
Asexual reproduction of the new Dendranthema plant by terminal vegetative cuttings was first conducted in a controlled greenhouse environment in Smoketown, Pa. in February, 2014 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 ‘Ice Pink Igloo’. These characteristics in combination distinguish ‘Ice Pink 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.
    • 5. Bright red purple-colored ray florets.
    • 6. Natural season flowering occurring about September 22 to 26 in Pennsylvania.
    • 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 primarily in ray floret color as plants of the female parent selection have bronze-colored ray florets. In addition, plants of the new Dendranthema are more outwardly spreading and flower later than plants of the female parent selection.
In side-by-side comparisons, plants of the new Dendranthema differ primarily from plants of the male parent, ‘Cool Yoigloo’, in the following characteristics:
    • 1. Plants of the new Dendranthema are larger and more outwardly spreading than plants of ‘Cool Yoigloo’.
    • 2. Inflorescences of plants of the new Dendranthema have fewer disc florets than inflorescences of plants of ‘Cool Yoigloo’.
    • 3. Inflorescences of plants of the new Dendranthema have better keeping quality than inflorescences of plants of ‘Cool Yoigloo’.
Plants of the new Dendranthema can be compared to plants of Chrysanthemum X morifolium ‘Dainty Pink Igloo’, disclosed in U.S. Plant Pat. No. 29,174. In side-by-side comparisons, plants of the new Dendranthema differ from plants of ‘Dainty Pink Igloo’ in the following characteristics:
    • 1. Plants of the new Dendranthema are larger and more outwardly spreading than plants of ‘Dainty Pink Igloo’.
    • 2. Plants of the new Dendranthema flower later than plants of ‘Dainty Pink Igloo’.
    • 3. Inflorescences of plants of the new Dendranthema are larger than inflorescences of plants of ‘Dainty Pink Igloo’.
    • 4. Plants of the new Dendranthema and ‘Dainty Pink Igloo’ differ in ray flower color as plants of ‘Dainty Pink Igloo’ have lighter-colored ray florets.
    • 5. Inflorescences of plants of the new Dendranthema have fewer disc florets than inflorescences of plants of ‘Dainty Pink Igloo’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS

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 is a side perspective view of a typical flowering plant of ‘Ice Pink Igloo’ grown in a container.
The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘Ice Pink Igloo’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations and measurements describe plants grown during the late summer and early autumn in 20-cm containers under full sunlight conditions in an outdoor nursery in Hermitage, Pa. and under cultural practices typical of commercial garden-type Dendranthema production.
