Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER508’, characterized by its compact, uniform, upright and mounded plant habit; moderately vigorous growth habit; freely and upright branching habit; very dark green-colored leaves with sinuate margins that give the leaves a textured appearance; under natural season conditions, plants flower on or about December 5 in Southern California; large inflorescences with burgundy-colored flower bracts; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: ‘PER508’.
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 cultivar name ‘PER508’.
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 attractive flower bracts and excellent post-production longevity.
The new Poinsettia plant is a naturally-occurring whole plant mutation of a proprietary selection of Euphorbia pulcherrima Willd. ‘Eckadire’, disclosed in U.S. Plant Pat. No. 12,846. The new Poinsettia plant was discovered and selected by the Inventor from within a population of plants of the mutation parent in a controlled greenhouse environment in Encinitas, Calif. on Sep. 14, 2007.
Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since January, 2008 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘PER508’. These characteristics in combination distinguish ‘PER508’ as a new and distinct Poinsettia plant:
    • 1. Compact, uniform, upright and mounded plant habit.
    • 2. Moderately vigorous growth habit.
    • 3. Freely and upright branching habit.
    • 4. Very dark green-colored leaves with sinuate margins that give the leaves a textured appearance.
    • 5. Under natural season conditions, plants flower on or about December 5 in Southern California.
    • 6. Large inflorescences with burgundy-colored flower bracts.
    • 7. Good post-production longevity.
In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differ primarily from plants of the mutation parent, ‘Eckadire’ in the following characteristics:
    • 1. Plants of the new Poinsettia are more compact and less vigorous than plants of ‘Eckadire’.
    • 2. Plants of the new Poinsettia and ‘Eckadire’ differ in leaf texture as plants of ‘Eckadire’ have smooth, not textured, leaves.
    • 3. Plants of the new Poinsettia and ‘Eckadire’ differ in flower bract color as plants of ‘Eckadire’ have dark red-colored flower bracts.
    • 4. Plants of the new Poinsettia flower about five days later than plants of ‘Eckadire’ when grown under natural season conditions.
Plants of the new Poinsettia can 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 the following characteristics:
    • 1. Plants of the new Poinsettia were more compact and less vigorous than plants of ‘490’.
    • 2. Plants of the new Poinsettia had a more upright branching habit than plants of ‘490’.
    • 3. Plants of the new Poinsettia and ‘490’ differed in flower bract color as plants of ‘490’ had dark red-colored flower bracts.
    • 4. Plants of the new Poinsettia flowered about 17 days later than plants of ‘490’ when grown under natural season conditions.
Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Eckanezka’, disclosed in U.S. Plant Pat. No. 19,192. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘Eckanezka’ in the following characteristics:
    • 1. Plants of the new Poinsettia and ‘Eckanezka’ differed in leaf texture as plants of ‘Eckanezka’ had smooth, not textured, leaves.
    • 2. Plants of the new Poinsettia and ‘Eckanezka’ differed in flower bract color as plants of ‘Eckanezka’ had dark red-colored flower bracts.
    • 3. Plants of the new Poinsettia flowered about 15 days later than plants of ‘Eckanezka’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Poinsettia plant 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 plant.
The photograph at the bottom of the sheet is a side perspective view of a typical flowering plant of ‘PER508’ grown in a container.
The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘PER508’.
 DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following detailed description were grown during the late autumn/early winter in 16.5-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under natural season conditions and cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures averaged 25° C., night temperatures averaged 20° C. and light levels averaged 5,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were 20 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.
