Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER11403’.

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 ‘PER11403’.

The new Poinsettia is a naturally-occurring whole plant mutation of the Euphorbia pulcherrima Willd. cultivar 490, disclosed in U.S. Plant Pat. No. 7,825. The cultivar PER11403 was discovered and selected by the Inventor as a flowering plant within a population of plants of the parent cultivar in a controlled environment in Encinitas, Calif., on Dec. 1, 2003. The new Poinsettia was selected on the basis of its early flowering habit.

Asexual reproduction of the new Poinsettia by terminal cuttings propagated 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.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PER11403’. These characteristics in combination distinguish ‘PER11403’ as a new and distinct cultivar:

    • 1. Uniform, compact, upright and mounded plant habit.
    • 2. Strong stems.
    • 3. Dark green-colored leaves.
    • 4. Inflorescences with dark red-colored flower bracts.
    • 5. Early-season flowering; natural season flower maturity date is late November for plants grown in Encinitas, Calif.
    • 6. Excellent post-production longevity.

Plants of the new Poinsettia differ from plants of the parent, the cultivar 490, primarily in time to flower as plants of the cultivar 490 flower about 10 days later than plants of the new Poinsettia.

Plants of the new Poinsettia can be compared to plants of the cultivar Bright Red Freedom, disclosed in U.S. Plant Pat. No. 10,572. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Bright Red Freedom in the following characteristics:

    • 1. Plants of the new Poinsettia flowered about two weeks earlier than plants of the cultivar Bright Red Freedom.
    • 2. Plants of the new Poinsettia had darker red-colored flower bracts than plants of the cultivar Bright Red Freedom.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Poinsettia, showing 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 the sheet comprises a side perspective view of a typical flowering plant of ‘PER11403’ grown in a container.

The photograph at the top left of the sheet is a close-up view of typical inflorescences of ‘PER11403’.

The photograph at the top right of the sheet is a top perspective view of a typical plant of ‘PER11403’.

 DETAILED BOTANICAL DESCRIPTION

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 aforementioned photographs, following observations and averaged measurements describe plants grown in Encinitas, Calif. during the winter under commercial practice in a polyethylene-covered greenhouse with day temperatures averaging about 24° C., night temperatures averaging about 19° C. and light levels about 4,000 foot-candles. Single plants were grown in 16.5-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 19 weeks from unrooted cuttings when the photographs and the detailed botanical description were taken. 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.
