Description
Botanical designation: Helleborus niger X Helleborus x hybridus.
Cultivar denomination: ‘COSEH 5800’.
An European Community Plant Breeder's Rights application for the instant plant was filed by the Inventor/Applicant, Mr. Josef Heuger of Glandorf, Germany, on Nov. 30, 2020, application number 2020/3088. Foreign priority is not claimed to this application.
The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor or Applicant. Inventor/Applicant claims a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.
The present invention relates to a new and distinct cultivar of Helleborus plant, botanically known as Helleborus niger X Helleborus x hybridus and hereinafter referred to by the name ‘COSEH 5800’.
The new Helleborus plant is a product of a planned breeding program conducted by the Inventor in Glandorf, Germany. The objective of the breeding program was to create new uniform Helleborus plants with unique and attractive plant habit, leaf and flower coloration and tolerance to biotic and abiotic stress.
The new Helleborus plant originated from a cross-pollination conducted by the Inventor in Glandorf, Germany in January, 2012 of a proprietary selection of Helleborus niger identified as code number P780, not patented, as the female, or seed, parent and an unnamed selection of Helleborus x hybridus, not patented, as the male, or pollen, parent. The new Helleborus plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Glandorf, Germany in December, 2013.
Asexual reproduction of the new Helleborus plant by in vitro axillary meristem culture in a controlled environment in Glandorf, Germany since April, 2014 has shown that the unique features of this new Helleborus plant are stable and reproduced true to type in successive generations.
Plants of the new Helleborus 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 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 ‘COSEH 5800’. These characteristics in combination distinguish ‘COSEH 5800’ as a new and distinct Helleborus plant:
-
- 1. Upright to slightly outwardly spreading and mounded plant habit.
- 2. Moderately vigorous growth habit.
- 3. Dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Large purplish red to reddish purple-colored flowers.
- 6. Good garden performance.
Plants of the new Helleborus differ from plants of the female parent selection in the following characteristics:
-
- 1. Leaves of plants of the new Helleborus are lighter green in color than leaves of plants of the female parent selection.
- 2. Flowers of plants of the new Helleborus are purplish red to reddish purple in color whereas flowers of plants of the female parent selection are white in color.
Plants of the new Helleborus differ from plants of the male parent selection in the following characteristics:
-
- 1. Leaf margins of plants of the new Helleborus are not as deeply serrate as leaf margins of plants of the male parent selection.
- 2. Flowers of plants of the new Helleborus are purplish red to reddish purple in color whereas flowers of plants of the male parent selection are reddish in color.
Plants of the new Helleborus can also be compared to plants of Helleborus niger X Helleborus x hybridus ‘LEM 100’, disclosed in U.S. Plant Pat. No. 25,646. In side-by-side comparisons, plants of the new Helleborus differ primarily from plants of ‘LEM 100’ in plant and growth habit as plants of the new Helleborus are more vigorous than and not as compact as plants of ‘LEM 100’.
The accompanying colored photographs illustrate the overall appearance of the new Helleborus 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 Helleborus plant.
The photograph on the left side of the photographic sheet (FIG. 1 ) is a side perspective view of a typical flowering plant of ‘COSEH 5800’ grown in a container.
The photograph on the right side of the photographic sheet (FIG. 2 ) is a close-up view of a typical flower of ‘COSEH 5800’.
The aforementioned photographs and following observations, measurements and values describe plants grown during late autumn and winter in 17-cm containers in a glass-covered greenhouse in Glandorf, Germany and under cultural practices typical of commercial Helleborus production. During the production of the plants, day temperatures ranged from 12° C. to 32° C. and night temperatures ranged from 5° C. to 12° C. Plants were eleven 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.
