USPP16947P2 - Poinsettia plant named ‘PER5102’ - Google Patents

Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER5102’, characterized by its uniform, upright and mounded plant habit; small dark green-colored leaves with irregularly scalloped margins; inflorescences with small, narrow, irregularly scalloped and red-colored flower bracts; mid-season flowering; showy orange-colored cyathia clusters; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER5102’.

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 ‘PER5102’.

The new Poinsettia is a naturally-occurring whole plant mutation of the Euphorbia pulcherrima Willd. cultivar 1019, not patented. The cultivar PER5012 was discovered and selected by the Inventor as a flowering plant within a population of plants of the parent cultivar in a controlled environment in Encinitas, Calif., on Sep. 27, 2001. The new Poinsettia was selected on the basis of its “textured” flower bracts.

Asexual reproduction of the new Poinsettia by terminal cuttings propagated in a controlled environment in Encinitas, Calif., since January, 2002, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.

BRIEF SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PER5102’. These characteristics in combination distinguish ‘PER5102’ as a new and distinct cultivar:

• • 1. Uniform, upright and mounded plant habit.
  • 2. Small dark green-colored leaves with irregularly scalloped margins.
  • 3. Inflorescences with small, narrow, irregularly scalloped and red-colored flower bracts.
  • 4. Mid-season flowering; natural season flower maturity date is late-November for plants grown in Encinitas, Calif.
  • 5. Showy orange-colored cyathia clusters.
  • 6. Excellent post-production longevity.

Plants of the new Poinsettia differ from plants of the parent, the cultivar 1019, in the following characteristics:

• • 1. Plants of the new Poinsettia have smaller leaves than plants of the cultivar 1019.
  • 2. Plants of the new Poinsettia have smaller and narrower flower bracts than plants of the cultivar 1019.

Plants of the new Poinsettia can be compared to plants of the cultivar Eckaloha, disclosed in U.S. Plant Pat. No. 13,341. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Eckaloha in the following characteristics:

• • 1. Plants of the new Poinsettia and the cultivar Eckaloha differed in leaf coloration.
  • 2. Plants of the new Poinsettia and the cultivar Eckaloha differed in flower bract coloration as plants of the cultivar Eckaloha had pale yellow and pink bi-colored flower bracts.

Plants of the new Poinsettia can also be compared to plants of the cultivar 490, disclosed in U.S. Plant Pat. No. 7,825. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar 490 in the following characteristics:

• • 1. Plants of the new Poinsetta and the cultivar 490 differed in leaf coloration.
  • 2. Plants of the new Poinsettia had smaller and narrower flower bracts than plants of the cultivar 490.
  • 3. Plants of the new Poinsettia flowered about 10 days later than plants of the cultivar 490.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Poinsettia, 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

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘PER5102’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘PER5102’.

DETAILED BOTANICAL DESCRIPTION

The new Poinsettia has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and averaged measurements describe plants grown in Encinitas, Calif. during the winter under commercial practice in a polyethylene-covered greenhouse with day temperatures averaging about 24° C., night temperatures averaging about 19° C. and light levels about 4,000 foot-candles. Single plants were grown in 16.5-cm pots and pinched once. Plants were flowered under natural season short day/long night conditions. Plants were about 21 weeks from unrooted cuttings when the photographs and the detailed botanical description were taken.
