Poinsettia plant named ‘PER16806’

Abstract

A new and distinct cultivar of poinsettia plant named ‘PER16806’, characterized by its uniform, upright, outwardly spreading and mounded plant habit; moderately vigorous growth habit; freely branching habit; dark green-colored leaves; early season flowering response; inflorescences with pink-colored flower bracts with dark pink-colored speckles; and good post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.

Cultivar denomination: ‘PER16806’.

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 ‘PER16806’.

The new Poinsettia plant is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘490’, disclosed in U.S. Plant Pat. No. 7,825. The new Poinsettia was discovered and selected by the Inventor as a single plant from within a population of plants ‘490’ in a controlled greenhouse environment in Forest Hills, Md. in November, 2005.

Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Forest Hills, Md. since January, 2006, 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. The phenotype may vary somewhat with variations in environment 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 ‘PER16806’. These characteristics in combination distinguish ‘PER16806’ as a new and distinct cultivar of Poinsettia:

• • 1. Uniform, upright, outwardly spreading and mounded plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit.
  • 4. Dark green-colored leaves.
  • 5. Early season flowering response; under natural season conditions, plants flower in about 7.5 weeks in Encinitas, Calif.
  • 6. Inflorescences with light pink-colored flower bracts covered with dark pink-colored speckles.
  • 7. Good post-production longevity.

In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the parent, ‘490’, primarily in flower bract color as plants of ‘490’ have dark red-colored flower bracts.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Amazone’, disclosed in U.S. Plant Pat. No. 12,604. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of ‘Amazone’ in the following characteristics:

• • 1. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Amazone’.
  • 2. Plants of the new Poinsettia flowered earlier than plants of ‘Amazone’ under natural season conditions.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Poinsettia. These photographs show 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 ‘PER16806’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘PER16806’.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and the following observations and measurements describe plants grown in Encinitas, Calif. during the autumn and winter in a polyethylene-covered greenhouse and under conditions and practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day temperatures averaged 24° C., night averaged 19° C. and light levels were about 4,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Single plants were grown in 15.25-cm pots and pinched one time. Plants had been growing for 17 weeks when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
