Abstract

A new and distinct cultivar of Poinsettia plant named ‘PER1055’, characterized by its inflorescences with bright red-colored flower bracts; dark green-colored leaves; uniform, compact, upright and mounded plant habit; early season flowering; natural season flower maturity date in late November for plants grown in Encinitas, Calif.; and excellent post-production longevity.

Description

Botanical designation: Euphorbia pulcherrima Willd.
Variety denomination: ‘PER1055’.
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 ‘PER1055’.
The new Poinsettia 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 early flowering Poinsettia cultivars having strong stems, attractive flower bract coloration, uniform plant habit and excellent post-production longevity.
The new Poinsettia originated from an open-pollination made by the Inventor in December, 1999, of two unidentified selections of Euphorbia pulcherrima Willd. The cultivar PER1055 was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Encinitas, Calif., in Dec., 2000.
Asexual reproduction of the new Poinsettia by terminal cuttings propagated in a controlled environment in Encinitas, Calif., since July, 2001, 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 ‘PER1055’. These characteristics in combination distinguish ‘PER1055’ as a new and distinct cultivar:
    • 1. Inflorescences with bright red-colored flower bracts.
    • 2. Dark green-colored leaves.
    • 3. Uniform, compact, upright and mounded plant habit.
    • 4. Early season flowering; natural season flower maturity date is late November for plants grown in Encinitas, Calif.
    • 5. Excellent post-production longevity.
Plants of the new Poinsettia can be compared to plants of the cultivar 490 (U.S. Plant Pat. No. 7,825). In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed primarily in time to flower as plants of the new Poinsettia flowered about one week later than plants of the cultivar 490. In addition, plants of the new Poinsettia had lighter-colored leaves and flower bracts than plants of the cultivar 490.
Plants of the new Poinsettia can also be compared to plants of the cultivar Angelika (U.S. Plant Pat. No. 5,492). In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia had brighter red-colored flower bracts 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 top of the sheet comprises a side perspective view of a typical flowering plant of ‘PER1055’ grown in a container.
The photograph at the bottom left of the sheet is a close-up view of typical inflorescences of ‘PER1055’.
The photograph at the bottom right of the sheet comprises a top perspective view of a typical plant of ‘PER1055’.
 DELAILED 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 autumn and 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 15 weeks from unrooted cuttings when the photographs and the detailed botanical 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.
