Abstract
A new and distinct cultivar of Poinsettia plant named ‘Stargazer White’, characterized by its uniform, strong, upright and mounded plant habit; freely branching habit; dark green-colored leaves; early flowering response; large inflorescences with creamy white-colored flower bracts; and excellent post-production longevity.
Description
Botanical designation: Euphorbia pulcherrima Willd.
Cultivar denomination: ‘STARGAZER WHITE’.
Referenced to related applications: Title: Poinsettia Plant Named ‘Stargazer Marble’. Applicant: Niels Arts. Plant patent application Ser. No. 12/214,231.
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 ‘Stargazer White’.
The new Poinsettia is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ‘Stargazer’, disclosed in U.S. Plant Pat. No. 17,022. The new Poinsettia was discovered and selected by the Inventor as a flowering plant within a population of plants of ‘Stargazer’ in a controlled greenhouse environment in Aalsmeer, The Netherlands in May, 2004.
Asexual reproduction of the new Poinsettia by terminal vegetative cuttings propagated in a controlled greenhouse environment in Aalsmeer, The Netherlands since July, 2004, has shown that the unique features of this new Poinsettia are stable and reproduced true to type in successive generations of asexual reproduction.
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 ‘Stargazer White’. These characteristics in combination distinguish ‘Stargazer White’ as a new and distinct cultivar of Poinsettia:
-
- 1. Uniform, strong, upright and mounded plant habit.
- 2. Freely branching habit.
- 3. Dark green-colored leaves.
- 4. Early flowering response.
- 5. Large inflorescences with creamy white-colored flower bracts.
- 6. Excellent post-production longevity.
In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Poinsettia differed from plants of ‘Stargazer’ primarily in flower bract color as plants of ‘Stargazer’ have dark red-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of the Euphorbia pulcherrima Willd. ‘Stargazer Marble’, disclosed in a U.S. Plant patent application Ser. No. 12/214,231. Plants of the new Poinsettia and ‘Stargazer Marble’ differ primarily in flower bract color as plants of ‘Stargazer Marble’ have creamy white and pink bi-colored flower bracts.
Plants of the new Poinsettia can be compared to plants of Euphorbia pulcherrima Willd. ‘Fiscor’, disclosed in U.S. Plant Pat. No. 9,364. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Poinsettia differed from plants of ‘Fiscor’ in the following characteristics:
-
- 1. Plants of the new Poinsettia were stronger than plants of ‘Fiscor’.
- 2. Plants of the new Poinsettia and ‘Fiscor’ differed in flower bract color as plants of ‘Fiscor’ have red-colored flower bracts.
- 3. Plants of the new Poinsettia had longer postproduction longevity than plants of ‘Fiscor’.
- 4. Plants of the new Poinsettia were more cold tolerant than plants of ‘Fiscor’.
The accompanying photograph illustrates the overall appearance of the new Poinsettia. The photograph shows 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 typical flowering plant of ‘Stargazer White’.
Plants used for the aforementioned photograph and following observations and measurements were grown in 13-cm containers in De Kwakel, The Netherlands during the autumn and winter in a glass-covered greenhouse and under conditions and cultural practices which approximate those generally used in commercial Poinsettia production. During the first ten weeks of production of the plants, day and night temperatures averaged 20° C. and during the finishing production phase, day and night temperatures averaged 17° C. Light levels throughout the entire production period were about 200 Watts per square meter. Plants were pinched one time and were forced into flower under short day/long night photoperiodic conditions. Plants were 18 weeks from planting when the photograph and the detailed 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.
