Description

Botanical designation: Euphorbia pulcherrima.

Cultivar denomination: ‘PER10606’.

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 ‘PER10606’.

The new Poinsettia is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘7-05’, not patented. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of plants ‘7-05’ in a controlled greenhouse environment in Encinitas, Calif. on Dec. 2, 2005.

Asexual reproduction of the new Poinsettia by terminal vegetative cuttings in a controlled greenhouse environment in Encinitas, Calif. since February, 2006, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

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 following traits have been repeatedly observed and are determined to be the unique characteristics of ‘PER10606’. These characteristics in combination distinguish ‘PER10606’ as a new and distinct cultivar of Poinsettia:

    • 1. Uniform, upright 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 seven weeks in Encinitas, Calif.
    • 6. Inflorescences with creamy white-colored flower bracts.
    • 7. Excellent post-production longevity.

In side-by-side comparisons conducted in Encinitas, Calif. plants of the new Poinsettia differed from plants of the parent, ‘7-05’, primarily in flower bract color as plants of ‘7-05’ have light pink and creamy white bi-colored flower bracts.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Peterstar White’, disclosed in U.S. Plant Pat. No. 9,878. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of ‘Peterstar White’ in the following characteristics:

    • 1. Plants of the new Poinsettia had darker green-colored leaves than plants of ‘Peterstar White’.
    • 2. Plants of the new Poinsettia flowered about three weeks earlier than plants of ‘Peterstar White’ under natural season conditions.
    • 3. Plants of the new Poinsettia and ‘Peterstar White’ differed slightly in flower bract color.

Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘490 White’, disclosed in U.S. Plant Pat. No. 8,772. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily from plants of ‘490 White’ in time to flower as plants of the new Poinsettia flowered about eleven days earlier than plants of ‘490 White’ 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 sheet comprises a side perspective view of a typical flowering plant of ‘PER10606’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical inflorescences of ‘PER10606’.

DETAILED BOTANICAL DESCRIPTION

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. Plants used in the aforementioned photographs and the following observations and measurements describe plants grown in Encinitas, Calif. during the 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 were three months old when the photographs and the detailed description were taken.
