Title: Poinsettia Plant Named ‘PER2010’

Applicant: Ruth Kobayashi

Filed: Concurrently with this application having U.S. Plant patent application Ser. No. 13/694,962

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 ‘PER2110’.

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 originated is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘PER1188’, disclosed in U.S. Plant Pat. No. 23,201. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘PER1188’ in a controlled greenhouse environment in Encinitas, Calif. on Sep. 22, 2009.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since January, 2010 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 ‘PER2110’. These characteristics in combination distinguish ‘PER2110’ as a new and distinct Poinsettia plant:

• • 1. Relatively compact, upright and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely and upright branching habit.
  • 4. Dark green-colored leaves.
  • 5. Early-season flowering response; under natural season conditions, plants flower in early November in Southern California.
  • 6. Large inflorescences with dark 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, ‘PER1188’, in flower bract color as plants of ‘PER1188’ have bright red-colored flower bracts with no flecking.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘PER2010’, disclosed in U.S. Plant patent application Ser. No. 13/694,962. Plants of the new Poinsettia and ‘PER2010’ differ primarily in flower bract color.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘490 Early 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 Early Pink’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than plants of ‘490 Early Pink’.
  • 2. Branching habit of plants of the new Poinsettia was more upright than branching habit of plants of ‘490 Early Pink’.
  • 3. Plants of the new Poinsettia had larger flower bracts than plants of ‘490 Early Pink’.

Plants of the new Poinsettia can also 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 primarily from plants of ‘Peterstar Pink’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than plants of ‘Peterstar Pink’.
  • 2. Branching habit of plants of the new Poinsettia was more upright than branching habit of plants of ‘Peterstar Pink’.
  • 3. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Peterstar Pink’.
  • 4. Plants of the new Poinsettia flowered about 18 days earlier than plants of ‘Peterstar Pink’ when grown under natural season conditions.
  • 5. Plants of the new Poinsettia had larger flower bracts than plants of ‘Peterstar Pink’.

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.
