Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER6904’, characterized by its uniform, upright, outwardly spreading and mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; early season flowering response; inflorescences with dark pink-colored flower bracts; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima.
Cultivar denomination: ‘PER6904’.
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 ‘PER6904’.
The new Poinsettia is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘PER11403’, disclosed in U.S. Plant Pat. No. 18,363. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of plants ‘PER11403’ in a controlled greenhouse environment in Encinitas, Calif. on Aug. 26, 2004.
Asexual reproduction of the new Poinsettia by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since October, 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 new Poinsettia 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 ‘PER6904’. These characteristics in combination distinguish ‘PER6904’ as a new and distinct cultivar of Poinsettia:
    • 1. Uniform, upright, outwardly spreading and mounded plant habit.
    • 2. Moderately 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 seven weeks in Encinitas, Calif.
    • 6. Inflorescences with dark 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 parent, ‘PER11403’, primarily in flower bract color as plants of ‘PER11403’ have dark red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘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 ‘Peterstar Pink’ in the following characteristics:
    • 1. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Peterstar Pink’.
    • 2. Plants of the new Poinsettia flowered about three weeks earlier than plants of ‘Peterstar Pink’ under natural season conditions.
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 ‘PER6904’ grown in a container. The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘PER6904’.
 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 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. Single plants were grown in 15.25-cm pots and pinched one time. Plants were three months old when the photographs and the detailed description were taken.
