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 ‘PER2109’.

The new Poinsettia plant originated is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘490’, disclosed in U.S. Plant Pat. No. 7,825. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘490’ in a controlled greenhouse environment in Encinitas, Calif. in December, 2006.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since December, 2007 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 ‘PER2109’. These characteristics in combination distinguish ‘PER2109’ 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. Dark green-colored leaves.
  • 5. Mid-season flowering response; under natural season conditions, plants flower in late November in Southern California.
  • 6. Large inflorescences with dusty pink-colored flower bracts covered with light red-colored random speckles and splotches.
  • 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, ‘490’, in flower bract color as plants of ‘490’ have dark red-colored flower bracts with no flecking. In addition, plants of the new Poinsettia are more compact than and not as vigorous as plants of ‘490’.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘PER2009’, disclosed in U.S. Plant patent application Ser. No. 13/694,964. Plants of the new Poinsettia and ‘PER2009’ differ primarily in flower bract color.

Plants of the new Poinsettia can also be compared to plants of the Euphorbia pulcherrima Willd. ‘3-91’, disclosed in U.S. Plant Pat. No. 9,602. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘3-91’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than and not as vigorous as plants of ‘3-91’.
  • 2. Leaves of plants of the new Poinsettia were darker green in color than leaves of plants of ‘3-91’.
  • 3. Plants of the new Poinsettia flowered about one week earlier than plants of ‘3-91’ when grown under natural season conditions.
  • 4. Plants of the new Poinsettia and ‘3-91’ differed in leaf and flower bract shape.

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 24° C., night temperatures averaged 18° 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 17 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.
