Poinsettia plant named ‘PER3809A’

Abstract

A new and distinct cultivar of poinsettia plant named ‘PER3809A’, characterized by its compact, uniform, upright and mounded plant habit; vigorous growth habit; freely branching habit; medium green-colored leaves; mid-season flowering response; large inflorescences with pink-colored flower bracts; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER3809A’.

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 ‘PER3809A’.

The new Poinsettia is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘Eckalbert’, disclosed in U.S. Plant patent application Ser. No. 10/291,043, abandoned. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Eckalbert’ in a controlled greenhouse environment in Encinitas, Calif. in July, 2008.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since January, 2009 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 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 ‘PER3809A’. These characteristics in combination distinguish ‘PER3809A’ as a new and distinct Poinsettia plant:

• • 1. Compact, uniform, upright and mounded plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Medium green-colored leaves.
  • 5. Mid-season flowering response; under natural season conditions, plants flower in late November in Southern California.
  • 6. Large inflorescences with pink-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 parent, ‘Eckalbert’ in plant habit as plants of the new Poinsettia are more compact than plants of ‘Eckalbert’.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘490 Pink’, disclosed in U.S. Plant Pat. No. 8,817. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘490 Pink’ in the following characteristics:

• • 1. Plants of the new Poinsettia had lighter green-colored leaves than plants of ‘490 Pink’.
  • 2. Plants of the new Poinsettia and ‘490 Pink’ differed in flower bract color as flower bracts of plants of ‘490 Pink’ were more bluish pink in color.

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 comprises a side perspective view of a typical flowering plant of ‘PER3809A’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘PER3809A’.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following description were grown during the 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 temperatures averaged 19° C. and light levels averaged 4,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were 18 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.
