Title: Helleborus Plant Named ‘COSEH 6600’
Inventor/Applicant: Josef Heuger
Filed: Concurrently with the instant application U.S. Plant patent application Ser. No. 16/873,637)
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 Jun. 6, 2019, application number 2019/1387. 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 exemption 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 x ballardiae X Helleborus x hybridus and hereinafter referred to by the name ‘COSEH 6400’.
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 December, 2012 of a proprietary selection of Helleborus x ballardiae identified as code number P839, not patented, as the female, or seed patent 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 January, 2015.
Asexual reproduction of the new Helleborus plant by in vitro axillary meristem culture in a controlled environment in Glandorf, Germany since March, 2015 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 6400’. These characteristics in combination distinguish ‘COSEH 6400’ as a new and distinct Helleborus plant:
-
- 1. Upright to slightly outwardly spreading and mounded plant habit.
- 2. Vigorous growth habit.
- 3. Dark green-colored leaves.
- 4. Freely flowering habit.
- 5. Light yellow green-colored flowers with greyed purple-colored margins.
- 6. Good garden performance.
Plants of the new Helleborus differ from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Helleborus are more vigorous than plants of the female parent selection.
- 2. Plants of the new Helleborus flower later than plants of the female parent selection.
Plants of the new Helleborus differ from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Helleborus are more vigorous than plants of the male parent selection.
- 2. Flowers of plants of the new Helleborus are light yellow green in color with greyed purple-colored margins whereas flowers of plants of the male parent selection are cream and brown in color.
Plants of the new Helleborus can be compared to plants of Helleborus x ballardiae X Helleborus x hybridus ‘COSEH 6500’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Helleborus differ primarily from plants of ‘COSEH 6500’ in plant and growth habit as plants of the new Helleborus are taller and more vigorous than plants of ‘COSEH 6500’.
Plants of the new Helleborus can be compared to plants of Helleborus x ballardiae X Helleborus x hybridus ‘COSEH 6600’, disclosed in a U.S. Plant Patent application filed concurrently. Plants of the new Helleborus differ primarily from plants of ‘COSEH 6600’ in flower color as plants of the new Helleborus have light yellow green-colored flowers with greyed purple-colored margins whereas plants of ‘COSEH 6600’ have greyed purple to greyed red-colored flowers. In addition, plants of the new Helleborus are taller and more vigorous than plants of ‘COSEH 6600’.
Plants of the new Helleborus can also be compared to plants of Helleborus x hybridus ‘ABCRD01’ (U.S. Plant Pat. No. 24,149) also known as trade name ‘Penny's Pink’. In side-by-side comparisons, plants of the new Helleborus differ primarily from plants of ‘Penny's Pink’ in the following characteristics:
-
- 1. Plants of the new Helleborus have dark green-colored leaves without distinct venation whereas plants of ‘Penny's Pink’ have green-colored leaves with distinct venation.
- 2. Plants of the new Helleborus differ from plants of ‘Penny's Pink’ in flower color as plants of the new Helleborus have light yellow green-colored flowers with greyed purple-colored margins whereas plants of ‘Penny's Pink’ have greyed purple-colored flowers.
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 (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘COSEH 6400’ grown in a container.
The photograph on the second sheet (FIG. 2 of 2) is a close-up view of a typical flower of ‘COSEH 6400’.
The aforementioned photographs and following observations, measurements and values describe plants grown during March 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 four 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.
