Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER1549’.

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 ‘PER1549’.

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 from a cross-pollination made by the Inventor in December, 2013 of a proprietary selection of Euphorbia pulcherrima Willd. identified as code number EZ09-000144-046, not patented, as the female, or seed, parent, with a proprietary selection of Euphorbia pulcherrima Willd. identified as code number EZ11-000125-043, not patented, as the male, or pollen, parent. The new Poinsettia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Encinitas, Calif. in December, 2014.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since July, 2015 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 ‘PER1549’. These characteristics in combination distinguish ‘PER1549’ as a new and distinct Poinsettia plant:

• • 1. Moderately compact, uniform, upright and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely and upright to somewhat outwardly branching habit.
  • 4. Dark green-colored leaves.
  • 5. Under natural season conditions, plants flower on or about November 25 in Southern California.
  • 6. Large inflorescences with bright yellow to yellow orange-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 female parent selection in flower bract color as plants of the new Poinsettia have bright yellow to yellow orange-colored flower bracts whereas plants of the female parent selection have light to golden yellow flower bracts with dark pink-colored flecks.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differ primarily from plants of the male parent selection in the following characteristics:

• • 1. Plants of the new Poinsettia are more compact than and not as vigorous as plants of the male parent selection.
  • 2. Plants of the new Poinsettia have darker green-colored leaves than plants of the male parent selection.
  • 3. Plants of the new Poinsettia have bright yellow to yellow orange-colored flower bracts whereas plants of the male parent selection have white to light yellow-colored flower bracts.

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, plants of the new Poinsettia differ primarily from plants of ‘PER975’ in the following characteristics:

• • 1. Plants of the new Poinsettia are more compact than and not as vigorous as plants of ‘PER975’.
  • 2. Plants of the new Poinsettia have darker green-colored leaves than plants of ‘PER975’.
  • 3. Plants of the new Poinsettia have bright yellow to yellow orange-colored flower bracts whereas plants of ‘PER975’ have pink to pale yellow-colored flower bracts.
  • 4. Plants of the new Poinsettia flower about four days later than plants of ‘PER975’ when grown under natural season conditions in Southern California.

Plants of the new Poinsettia can also be compared to plants of the Euphorbia pulcherrima Willd. ‘PER1409’, disclosed in U.S. Plant Pat. No. 27,850. In side-by-side comparisons, plants of the new Poinsettia differ primarily from plants of ‘PER1409’ in the following characteristics:

• • 1. Plants of the new Poinsettia are more compact than plants of ‘PER1409’.
  • 2. Plants of the new Poinsettia have bright yellow to yellow orange-colored flower bracts whereas plants of ‘PER1409’ have light yellow and peach-colored flower bracts with dark pink-colored flecks and spots.
  • 3. Plants of the new Poinsettia flower about eight days later than plants of ‘PER1409’ when grown under natural season conditions in Southern California.

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 on the first sheet is a side to top perspective view of a typical flowering plant of ‘PER1549’ grown in a 16.5-cm container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘PER1549’ grown in a 16.5-cm container.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and in the following detailed description were grown during the late autumn and early winter in 16.5-cm (plants used for the photographs and description) and 20-cm containers (plants used for the description only) 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 ranging from 4,500 to 5,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. A single plant was grown in the 16.5-cm containers and it was pinched one time. Four plants were grown in the 20-cm containers and they were not pinched. Plants were 23 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, 2017 Edition, except where general terms of ordinary dictionary significance are used.
