Abstract

A new and distinct cultivar of Poinsettia plant named ‘Firework’, characterized by its red and sharply pointed flower bracts that are held somewhat upright; dark green leaves; compact, uniform, upright and outwardly spreading plant habit; very freely branching habit; early flowering; and excellent post-production longevity.

Description

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 ‘Firework’.
The new Poinsettia is a naturally-occurring whole plant mutation of the Euphorbia pulcherrima Willd. cultivar Red Baron, disclosed in U.S. Plant Pat. No. 10,162. The new Poinsettia was discovered and selected by the Inventor in March, 1997, in a controlled environment in Blanzac, France. Compared to plants of the parent cultivar, plants of the new Poinsettia have lighter red flower bract color.
Asexual reproduction of the new Poinsettia by terminal cuttings taken at Encinitas, Calif., 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 ‘Firework’. These characteristics in combination distinguish ‘Firework’ as a new and distinct cultivar:
1. Bright red and sharply pointed flower bracts that are held somewhat upright.
2. Dark green leaves.
3. Compact, uniform, upright and outwardly spreading plant habit.
4. Very freely branching habit.
5. Early flowering.
6. Excellent post-production longevity.
Plants of the new Poinsettia can be compared to plants of the Poinsettia cultivar Peterstar, disclosed in U.S. Plant Pat. No. 8,259. In side-by-side comparisons conducted in Encinitas, Calif., plants of the new Poinsettia differed from plants of the cultivar Peterstar in the following characteristics:
1. Plants of the new Poinsettia are taller and more uniform in plant habit than plants of the cultivar Peterstar.
2. Plants of the new Poinsettia are more freely branching than plants of the cultivar Peterstar.
3. Plants of the new Pointsettia have darker green leaves than plants of the cultivar Peterstar.
4. Plants of the new Poinsettia root more quickly than plants of the cultivar Peterstar.
5. Flower bracts of the new Poinsettia are shorter, narrower more pointed and held more upright than flower bracts of the cultivar Peterstar.
6. Flower bract color of the new Poinsettia is more crimson red than flower bract color of the cultivar Peterstar.
7. Plants of the new Poinsettia have longer post-production longevity than plants of the cultivar Peterstar.
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 actual colors of the new Poinsettia.
The photograph at the top of the first sheet comprises a side perspective view of a typical plant of ‘Firework’.
The photograph at the bottom of the first sheet comprises a top perspective view of a typical plant of ‘Firework’.
The photograph on the second sheet is a close-up view of typical bracts and leaves of ‘Firework’ (left) and ‘Peterstar’ (right).
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 following observations and measurements describe plants grown in Encinitas, Calif., under commercial practice in a glass-covered greenhouse with day temperatures about 21 to 27° C., night temperatures about 18 to 20° C., and light levels about 4,000 foot-candles. Plants were grown in 16.5-cm pots, pinched one time, and flowered under naturally lengthening nights during the fall.
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
