Abstract
A new and distinct cultivar of Euphorbia plant named ‘Bonpr 974BK’, characterized by its upright and mounded plant habit; moderately vigorous growth habit; freely branching habit; large inflorescences with white-colored flower bracts; and good post-production longevity.
Description
Botanical designation: Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra,
Cultivar denomination: ‘BONPR 974BK’.
The present invention relates to a new and distinct cultivar of Euphorbia plant, an interspecific hybrid botanically known as Euphorbia pulcherrimaWilld. ex Klotzsch X Euphorbia cornastra, and hereinafter referred to by the cultivar name ‘Bonpr 974BK’.
The new Euphorbia plant is a naturally-occurring whole plant mutation of Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra ‘Bonpri 974’, disclosed in U.S. Plant Pat. No. 27,689. The new Euphorbia plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Bonpri 974 ’ in a controlled greenhouse environment in Maasdijk, The Netherlands in November, 2019.
Asexual reproduction of the new Euphorbia plant by terminal vegetative cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since August, 2020 has shown that the unique features of this new Euphorbia plant are stable and reproduced true to type in successive generations of asexual reproduction.
Plants of the new Euphorbia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Bonpr 974BK’. These characteristics in combination distinguish ‘Bonpr 974BK’ as a new and distinct Euphorbia plant:
-
- 1. Upright and mounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Freely branching habit.
- 4. Large inflorescences with white-colored flower bracts.
- 5. Good post-production longevity.
Plants of the new Euphorbia differ primarily from plants of the mutation parent, Bonpri 974’ in plant and growth habit. Plants of the new Euphorbia flower are larger and more vigorous than and not as compact as plants of ‘Bonpri 974’. In addition, plants of the new Euphorbia have larger leaves than plants of ‘Bonpri 974’.
Plants of the new Euphorbia can be compared to plants of the Euphorbia pulcherrima Willd. ex Klotzsch X Euphorbia cornastra ‘Bonpri 635’, disclosed in U.S. Plant Pat. No. 25,116. In side-by-side comparisons, plants of the new Euphorbia differ primarily from plants of ‘Bonpri 635’ in the following characteristics:
-
- 1. Plants of the new Euphorbia are taller than plants of ‘Bonpri 635’.
- 2. Plants of the new Euphorbia have larger flower bracts than plants of ‘Bonpri 635’.
- 3. Plants of the new Euphorbia and ‘Bonpri 635’ differ in flower bract color as flower bracts of plants of the new Euphorbia are white in color whereas flower bracts of plants of ‘Bonpri 635’ are white in color with red purple-colored venation and occasional random spots.
The accompanying photographs illustrate the overall appearance of the new Euphorbia plant 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 Euphorbia plant.
The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘Bonpr 974BK’ grown in a container.
The photograph on the second sheet (FIG. 2 ) is a close-up view of a typical flowering plant of ‘Bonpr 974BK’.
Plants used in the aforementioned photographs and described herewith in detail were grown during the autumn and early winter in 10.5-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Euphorbia production. During the production of the plants, day temperatures averaged 23° C. and night temperatures averaged 13° C. Plants were six months old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
