Poinsettia plant named ‘PER713’

Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER7_13’, characterized by its relatively compact, uniform, upright and mounded plant habit; moderately vigorous growth habit; freely and upright to somewhat outwardly branching habit; very dark green-colored leaves; large inflorescences with golden yellow-colored flower bracts; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER7_13’.

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 ‘PER7_13’.

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 Euphorbia pulcherrima Willd. ‘PER1409’, disclosed in U.S. Plant Pat. No. 27,850. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘PER1409’ in a controlled greenhouse environment in Encinitas, Calif. on Sep. 6, 2012.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since January, 2013 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 ‘PER7_13’. These characteristics in combination distinguish ‘PER7_13’ as a new and distinct Poinsettia plant:

• • 1. Relatively compact, uniform, upright and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely and upright to somewhat outwardly branching habit.
  • 4. Very dark green-colored leaves.
  • 5. Under natural season conditions, plants flower on or about November 17 in Southern California.
  • 6. Large inflorescences with golden yellow-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, ‘PER1409’, in the following characteristics:

• • 1. Plants of the new Poinsettia are more compact than plants of ‘PER1409’.
  • 2. Plants of the new Poinsettia and ‘PER1409’ differ in fully expanded flower bract color as plants of ‘PER1409’ have light yellow and peach-colored flower bracts with dark pink-colored flecks and spots.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘PER10606’, disclosed in U.S. Plant Pat. No. 20,351. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘PER10606’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than plants of ‘PER10606’.
  • 2. Plants of the new Poinsettia were more upright than plants of ‘PER10606’.
  • 3. Plants of the new Poinsettia and ‘PER10606’ differed in flower bract color as plants of ‘PER10606’ had creamy white-colored flower bracts.
  • 4. Plants of the new Poinsettia flowered about ten days later than plants of ‘PER10606’ when grown under natural season conditions in Southern California.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘PER975’, disclosed in U.S. Plant Pat. No. 16,882. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘PER975’ in the following characteristics:

• • 1. Plants of the new Poinsettia were more compact than and not as vigorous as plants of ‘PER975’.
  • 2. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘PER975’.
  • 3. Plants of the new Poinsettia and ‘PER975’ differed in flower bract color as plants of ‘PER975’ had light pink to pale yellow-colored flower bracts.
  • 4. Plants of the new Poinsettia flowered about four days earlier than plants of ‘PER975’ when grown under natural season conditions in Southern California.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following detailed description were grown during the late autumn/early winter in quart (plants for the photographs) and 16.5-cm containers (plants used for the description) in a polyethylene-covered greenhouse in Encinitas, Calif. under natural season conditions and cultural practices typical of commercial Poinsettia production. During the production of the plants, day temperatures averaged 26° 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 19 and 25 weeks old for the quart and 16.5-cm containers, respectively, 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.
