Description
Botanical designation: Helleborus niger×Helleborus lividus.
Cultivar denomination: ‘COSEH 940’.
The present invention relates to a new and distinct cultivar of Helleborus plant, botanically known as Helleborus niger×Helleborus lividus, and hereinafter referred to by the name ‘COSEH 940’.
The new Helleborus plant is a product of a planned breeding program 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 resistance to pests.
The new Helleborus plant originated from a cross-pollination conducted by the Inventor in Glandorf, Germany in December, 2006 of an unnamed proprietary seedling selection of Helleborus niger, not patented, as the female, or seed, parent with an unnamed proprietary seedling selection of Helleborus lividus, 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 November, 2008.
Asexual reproduction of the new Helleborus plant by divisions in a controlled greenhouse environment in Glandorf, Germany since February, 2009 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 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 940’. These characteristics in combination distinguish ‘COSEH 940’ as a new and distinct Helleborus plant:
-
- 1. Upright and uniformly mounded plant habit.
- 2. Uniform and freely flowering habit.
- 3. Dark green-colored leaves.
- 4. Long flowering period.
- 5. Single white to light yellow green-colored flowers that are slightly tinged with greyed purple.
- 6. Good garden performance.
Compared to plants of the parent selections, plants of the new Helleborus are more uniformly mounded and are more uniformly and freely flowering.
Plants of the new Helleborus can be compared to plants of Helleborus niger×Helleborus lividus ‘COSEH 710’, disclosed in U.S. Plant Pat. No. 21,063. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Helleborus differed from plants of ‘COSEH 710’ in leaf and flower color.
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 first sheet comprises a side perspective view of a typical flowering plant of ‘COSEH 940’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flowering plant of ‘COSEH 940’.
The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in 15-cm containers in a glass-covered greenhouse in Glandorf, Germany and under environmental conditions and cultural practices which closely approximate commercial Helleborus production. During the production of the plants, day temperatures ranged from 12° C. to 32° C. and night temperatures ranged from 3° C. to 18° C. Plants were 14 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, 2007 Edition, except where general terms of ordinary dictionary significance are used.
