Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1232’, characterized by its uniform, upright and mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; mid-season flowering response; under natural season conditions, plants flower in about nine weeks in Southern California; large inflorescences with upright dark red-colored flower bracts; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: ‘PER1232’.
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 ‘PER1232’.
The new Poinsettia plant is a product of a planned breeding program conducted by the Inventor in Encinitas, Calif. The objective of the breeding program is to create new uniform Poinsettia plants having large inflorescences with red-colored flower bracts, mid-season flowering habit and excellent post-production longevity.
The new Poinsettia plant originated from a cross-pollination made by the Inventor in December, 2004 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number 04-4847, not patented, as the female, or seed, parent, with Euphorbia pulcherrima Willd. ‘PER1090’, disclosed in U.S. Plant Pat. No. 18,203, as the male, or pollen, parent. The new Poinsettia plant 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, 2005.
Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since July, 2006, has shown that the unique features of this new Poinsettia plant are stable and reproduced true to type in successive generations of asexual reproduction.
SUMMARY OF THE INVENTION
Plants of the new Poinsettia have 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 ‘PER1232’. These characteristics in combination distinguish ‘PER1232’ as a new and distinct cultivar of Poinsettia plant:
    • 1. Uniform, upright and mounded plant habit.
    • 2. Moderately 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 Southern California.
    • 6. Large inflorescences with upright dark red-colored flower bracts.
    • 7. Good 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 flower bract color as plants of the female parent selection had lighter 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, ‘PER1090’, in the following characteristics:
    • 1. Plants of the new Poinsettia were not as vigorous as plants of ‘PER1090’.
    • 2. Flower bracts of plants of the new Poinsettia were darker red in color than flower bracts of plants of ‘PER1090’.
    • 3. Plants of the new Poinsettia flowered five days later than plants of ‘PER1090’ when grown under natural season conditions.
Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘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 ‘Peterstar’ in the following characteristics:
    • 1. Leaves of plants of the new Poinsettia were darker green in color than leaves of plants of ‘Peterstar’.
    • 2. Flower bracts of plants of the new Poinsettia were darker red in color than flower bracts of plants of ‘Peterstar’.
    • 3. Plants of the new Poinsettia flowered about six days later than plants of ‘Peterstar’ when grown under natural season conditions.
Plants of the new Poinsettia can also be compared to plants of the Euphorbia pulcherrima Willd. ‘490’, disclosed in U.S. Plant Pat. No. 7,825. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘490’ in time to flower as plants of the new Poinsettia flowered about 13 days later than plants of ‘490’ when grown under natural season conditions.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Poinsettia plant. 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 plant.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘PER1232’ grown in a container.
The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘PER1232’.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following description describe plants grown in during the autumn and early winter in 15-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under natural season conditions and cultural practices which approximate those 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. Plants were pinched one time and were 19 weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
