Abstract
A new and distinct cultivar of Poinsettia plant named ‘Winterfest White’, characterized by its uniform plant growth habit; dark green-colored leaves with green-colored petioles; mid-season flowering habit; inflorescences with white-colored flower bracts; and excellent post-production longevity.
Description
Euphorbia pulcherrima Willd. cultivar Winterfest White.
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 ‘Winterfest White’.
The new Poinsettia is a product of a planned breeding program conducted by the Inventor in Lompoc, Calif. The objective of the breeding program is to create new Poinsettia cultivars with uniform plant habit and attractive flower bract coloration.
The new Poinsettia is a induced mutation of the Euphorbia pulcherrima Willd. cultivar Winterfest Marble, not patented. The new Poinsettia was discovered and selected by the Inventor as a single plant within a population of irradiated plants of the cultivar Winterfest Marble in a controlled environment in Lompoc, Calif. The selection of this plant was based on its attractive flower bract coloration and uniform plant habit.
Asexual reproduction of the new Poinsettia by vegetative terminal cuttings taken at Lompoc, Calif., has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Winterfest White’. These characteristics in combination distinguish ‘Winterfest White’ as a new and distinct cultivar:
1. Uniform plant growth habit.
2. Dark green-colored leaves with green-colored petioles.
3. Mid-season flowering habit.
4. Inflorescences with white-colored flower bracts.
5. Excellent post-production longevity.
Plants of the new Poinsettia differ primarily from plants of the parent cultivar in flower bract coloration as plants of the cultivar Winterfest Marble have pink and white bi-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the cultivar 490 White, disclosed in U.S. Plant Pat. No. 8,772. In side-by-side comparisons conducted in Lompoc, Calif., plants of the new Poinsettia differed from plants of the cultivar 490 White in the following characteristics:
1. Plants of the new Poinsettia were taller and not as outwardly spreading as plants of the cultivar 490 White.
2. Plants of the new Poinsettia flowered about 7 to 10 days later than plants of the cultivar 490 White under controlled photoperiod conditions.
3. Plants of the new Poinsettia had more cyathia per corymb than plants of the cultivar 490 White.
The accompanying colored photograph illustrates 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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Poinsettia. The photograph comprises a top perspective view of a single flowering plant of ‘Winterfest White’ grown in a container.
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 photograph and, following observations and measurements describe plants grown in Lompoc, Calif. during the fall and winter under commercial practice in a fiberglass-covered greenhouse with night temperatures about 16° C. and light levels about 3,000 to 4,000 foot-candles. Single plants were grown in 15-cm pots, pinched once, and flowered under controlled short day/long night conditions. Plants were about 17 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.
