Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: ‘PER14606’.
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 ‘PER14606’.
The new Poinsettia plant is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘Eckakeem’, disclosed in U.S. Plant Pat. No. 13,838. The new Poinsettia plant was discovered and selected by the Inventor as a flowering plant from within a population of plants of ‘Eckakeem’ in a controlled greenhouse environment in Stratford-upon-Avon, Warwickshire, United Kingdom in August, 2005.
Asexual reproduction of the new Poinsettia plant by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since June, 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 ‘PER14606’. These characteristics in combination distinguish ‘PER14606’ as a new and distinct cultivar of Poinsettia plant:
- 1.. Uniform, upright and mounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Green and pale yellow variegated leaves.
- 5. Mid-season flowering response; under natural season conditions, plants flower in about nine weeks in Southern California.
- 6. Large inflorescences with red-colored flower bracts.
- 7. Good post-production longevity.
In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of the parent, ‘Eckakeem’, in the following characteristics:
- 1. Plants of the new Poinsettia were more compact than plants of ‘Eckakeem’.
- 2. Leaves of plants of the new Poinsettia were green and pale yellow variegated whereas leaves of plants of ‘Eckakeem’ were dark green in color.
Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Eckansley’, disclosed in U.S. Plant Pat. No. 11,889. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘Eckansley’ in the following characteristics:
- 1. Plants of the new Poinsettia were more vigorous than and not as compact as plants of ‘Eckansley’.
- 2. Plants of the new Poinsettia were more freely branching than plants of ‘Eckansley’.
- 3. Plants of the new Poinsettia had stronger lateral branches than plants of ‘Eckansley’.
- 4. The leaf variegation contrast of plants of the new Poinsettia was greater than the leaf variegation contrast of plants of ‘Eckansley’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Poinsettia plant. The 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 plant.
The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘PER14606’ grown in a container.
The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘PER14606’.
DETAILED BOTANICAL DESCRIPTION
Plants used in the aforementioned photographs and in the following description describe plants grown in during the winter in 15-cm containers in a polyethylene-covered greenhouse in Encinitas, Calif. and under natural season conditions and cultural practices which approximate those generally used in commercial Poinsettia production. During the production of the plants, day temperatures averaged 25° C., night averaged 17° C. and light levels were about 4,000 foot-candles. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time and were 18 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, 2007 Edition, except where general terms of ordinary dictionary significance are used.
