Abstract

A new and distinct cultivar of Poinsettia plant named `PER1180`, characterized by its uniform, upright, outwardly spreading and mounded plant habit; vigorous growth habit; freely branching habit; dark green-colored leaves; mid-season flowering response; inflorescences with dark orange-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima.

Cultivar denomination: `PER1180`.

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 `PER1180`.

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, 2002 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 02-3535, not patented, as the female, or seed, parent, with a proprietary Poinsettia selection identified as PE1-1, not patented, as the male, or pollen, parent. The cultivar PER1180 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Encinitas, Calif. in December, 2003. 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, 2004, 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 PER1180 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 `PER1180`. These characteristics in combination distinguish `PER1180` as a new and distinct cultivar of Poinsettia: 1. Uniform, upright, outwardly spreading and mounded plant habit. 2. Vigorous growth habit. 3. Freely branching habit. 4. Dark green-colored leaves. 5. Mid-season flowering response; under natural season conditions, plants flower in about nine weeks in Encinitas, Calif. 6. Inflorescences with dark orange-colored flower bracts. 7. Excellent post-production longevity.

In side-by-side comparisons conducted in Encinitas, Calif. plants of the new Poinsettia differed primarily from plants of the female parent selection in plant uniformity and leaf color.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of the male parent selection in flower bract shape.

Plants of the new Poinsettia can be compared to plants of the Poinsettia cultivar Eckadire, disclosed in U.S. Plant Pat. No. 12,846. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Eckadire in the following characteristics: 1. Plants of the new Poinsettia were less vigorous than plants of the cultivar Eckadire. 2. Plants of the new Poinsettia and cultivar Eckadire differed in flower bract color.

Plants of the new Poinsettia can also be compared to plants of the Poinsettia cultivar Peterstar, disclosed in U.S. Plant Pat. No. 8,259. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Peterstar in the following characteristics: 1. Plants of the new Poinsettia had darker green-colored leaves than plants of the cultivar Peterstar. 2. Plants of the new Poinsettia and the cultivar Peterstar differed in flower bract shape. 3. Plants of the new Poinsettia and cultivar Peterstar differed in flower bract color.

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 spring in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day temperatures averaged 24.degree. C., night averaged 19.degree. 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. Botanical classification: Euphorbia pulcherrima cultivar PER1180.
