Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1120’, characterized by its uniform, upright, outwardly spreading and mounded plant habit; vigorous growth habit; freely branching habit; dark green-colored leaves; early season flowering response; inflorescences with hot cherry pink-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima.
Cultivar denomination: ‘PER1120’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Poinsettia plant, botanically known as Euphorbia pulcherrima Willd., and hereinafter referred to by the name ‘PER1120’.
The new Poinsettia a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new Poinsettia cultivars having flower bracts with desirable colors, uniform plant habit and excellent post-production longevity.
The new Poinsettia originated from a cross-pollination made by the Inventor in December, 2001 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number Z-7, not patented, as the female, or seed, parent, with a proprietary Poinsettia selection identified as X-47, not patented, as the male, or pollen, parent. The cultivar PER1090 wad discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Encinitas, Calif. in December, 2002. The selection of this plant was based on its attractive flower bract colors and good plant form and substance.
Asexual reproduction of the new Poinsettia by terminal vegetative cuttings in a controlled environment in Encinitas, Calif. since January, 2003, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
The cultivar PER1120 has not been observed under all possible environmental 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 ‘PER1120’. These characteristics in combination distinguish ‘PER1120’ as a new and distinct cultivar of Poinsettia:
    • 1. Uniform, upright, outwardly spreading and mounted plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Dark green-colored leaves.
    • 5. Early season flowering response; under natural season conditions, plants flower in about 8.5 weeks in Encinitas, California.
    • 6. Inflorescences with hot cherry pink-colored flower bracts.
    • 7. Excellent post-production longevity.
In side-by-side comparisons conducted in Encinitas, Calif. plants of the new Poinsettia differed from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Poinsettia flower earlier than plants of the female parent selection.
    • 2. Plants of the new Poinsettia and the female parent selection differ in flower bract color as plants of the female parent selection have light red-colored flower bracts.
In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Poinsettia are more vigorous than plants of the male parent section.
    • 2. Plants of the new Poinsettia have darker green-colored leaves than plants of the male parent selection.
    • 3. Plants of the new Poinsettia and the male parent selection differ in flower bract color as plants of the male parent selection have bright red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the Poinsettia cultivar Peterstar Pink, disclosed in U.S. Plant Pat. No. 9,879. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Peterstar Pink in the following characteristics:
    • 1. Plants of the new Poinsettia were more vigorous than plants of the cultivar Peterstar Pink.
    • 2. Plants of the new Poinsettia had darker green-colored leaves than plants of the cultivar Peterstar Pink.
    • 3. Plants of the new Poinsettia and cultivar Peterstar Pink differed in flower bract color.
Plants of the new Poinsettia can also be compared to plants of the Poinsettia cultivar 490 Pink, Disclosed in U.S. Plant Pat. No. 8,817. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar 490 Pink in the following characteristics:
    • 1. Plants of the new Poinsettia were more vigorous than plants of the cultivar 490 Pink.
    • 2. Plants of the new Poinsettia flowered later than plants of the cultivar 490 Pink.
    • 3. Plants of the new Poinsettia and cultivar 490 Pink differed in flower bract color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Poinsettia. These photographs show 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 Poinsettia.
The photograph at the bottom of sheet comprises a side perspective view of a typical flowering plant of ‘PER1120’ grown in a container.
The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘PER1120’.
 DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Plants used in the aforementioned photographs and the following observations and measurements describe plants grown in Encinitas, Calif. during the winter in a polyethylene-covered greenhouse and under conditions and practices which approximate these generally used in commercial Poinsettia production. During the production of the plants, day temperatures averaged 24° C., night averaged 19° C. and light levels were about 4,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 16.5-cm pots and pinched one time. Plants were about 14 weeks old when the photographs and the detailed description were taken.
