Abstract
A new and distinct cultivar of Helleborus plant named ‘EPB 32’, characterized by its upright and mounding plant habit; uniform, continuous and freely flowering habit; relatively large dark purple-colored flowers that are held above the foliar plane on relatively long peduncles; and good garden performance.
Description
Botanical designation: Helleborus×hybridus.
Cultivar denomination: ‘EPB 32’.
The present invention relates to a new and distinct cultivar of Helleborus plant, botanically known as Helleborus×hybridus and hereinafter referred to by the name ‘EPB 32’.
The new Helleborus plant is a product of a planned breeding program conducted by the Inventors in Devon, United Kingdom. The objective of the breeding program was to create new freely-flowering Helleborus plants with strong peduncles that hold numerous attractive flowers above the foliar plane.
The new Helleborus plant originated from a cross-pollination conducted by the Inventors in Devon, United Kingdom on Jan. 23, 2008 of a proprietary seedling selection of Helleborus×hybridus identified as code designation BGE-8855, as the female, or seed, parent, not patented, with a proprietary seedling selection of Helleborus×hybridus identified as code designation EDB-469, as the male, or pollen, parent, not patented. The new Helleborus plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Devon, United Kingdom on Feb. 16, 2010.
Asexual reproduction of the new Helleborus plant by tissue culture in a controlled greenhouse environment in Roelofarendsveen, The Netherlands since Apr. 10, 2013, 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 of the new Helleborus plant may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype of the new Helleborus plant.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘EPB 32’. These characteristics in combination distinguish ‘EPB 32’ as a new and distinct Helleborus plant:
-
- 1. Upright and mounding plant habit.
- 2. Uniform, continuous and freely flowering habit.
- 3. Relatively large dark purple-colored flowers that are held above the foliar plane on relatively long peduncles.
- 4. 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 shorter than plants of the female parent selection.
- 2. Plants of the new Helleborus and the female parent selection differ in flower color as plants of the female parent selection have lighter purple-colored flowers.
Plants of the new Helleborus differ from plants of the male parent selection in the following characteristics:
-
- 1. Plants of the new Helleborus are shorter than plants of the male parent selection.
- 2. Plants of the new Helleborus and the male parent selection differ in flower color as plants of the male parent selection have lighter purple-colored flowers.
Plants of the new Helleborus can be compared to plants of Helleborus×hybridus ‘ABCRD02’, disclosed in U.S. Plant Pat. No. 24,720. In side-by-side comparisons conducted in Devon, United Kingdom, plants of the new Helleborus differed from plants of ‘ABCRD02’ in the following characteristics:
-
- 1. Plants of the new Helleborus were broader than plants of ‘ABCRD02’.
- 2. Leaves of plants of the new Helleborus were smaller and lighter green in color than leaves of plants of ‘ABCRD02’.
- 3. Plants of the new Helleborus were more freely flowering than plants of ‘ABCRD02’.
- 4. Plants of the new Helleborus and ‘ABCRD02’ differed in flower color as plants of ‘ABCRD02’ had lighter 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 is a side perspective view of a typical flowering plant of ‘EPB 32’ grown in a container.
The photograph on the second sheet is a close-up view of a typical flower of ‘EPB 32’.
The aforementioned photographs and following observations, measurements and values describe plants grown during the winter in three-liter containers in an outdoor nursery in Boijl, The Netherlands and under cultural practices typical of commercial Helleborus production. During the production of the plants, day temperatures ranged from 0° C. to 10° C. and night temperatures ranged from −15° C. to 0° C. Plants were one year old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
