Abstract
A new and distinct cultivar of Helleborus plant named ‘HGC Green Corsican’, characterized by its compact and mounded plant habit; dark green-colored leaves; and white-colored flowers.
Description
Botanical classification/cultivar designation: Helleborus niger×H. argutifolius cultivar HGC Green Corsican.
The present Invention relates to a new and distinct cultivar of Helleborus plant, botanically known as Helleborus niger×H. argutifolius, and hereinafter referred to by the cultivar name HGC Green Corsican.
The new Helleborus 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 Helleborus cultivars with a good plant habit, that flower for a long period of time, and have attractive flower coloration.
The new Helleborus originated from a cross-pollination made by the Inventor in January, 1999 in Glandorf, Germany of an unnamed seedling of Helleborus niger, not patented, as the female, or seed, parent with an unnamed seedling of Helleborus argutifolius, not patented, as the male, or pollen, parent. The new Helleborus was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Glandorf, Germany.
Asexual reproduction of the new cultivar by divisions at Glandorf, Germany since March, 2001, has shown that the unique features of this new Helleborus are stable and reproduced true to type in successive generations.
Plants of the cultivar HGC Green Corsican have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light level without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘HGC Green Corsican’. These characteristics in combination distinguish ‘HGC Green Corsican’ as a new and distinct cultivar of Helleborus:
-
- 1. Compact and mounded plant habit.
- 2. Dark green-colored leaves.
- 3. White-colored flowers.
Plants of the new Helleborus have less leaf serration and flower about two months later than plants of the female parent. Compared to plants of the male parent, plants of the new Helleborus have less leaf serration, flower about one month earlier and differ in flower coloration.
Plants of the new Helleborus can be compared to the Helleborus niger cultivar HGC Jericho, disclosed in U.S. Plant patent application Ser. No. 10/878,420. In side-by-side comparisons conducted in Glandorf, Germany, plants of the new Helleborus differed from plants of the cultivar HGC Jericho in the following characteristics:
-
- 1. Plants of the new Helleborus were taller than plants of the cultivar HGC Jericho.
- 2. Plants of the new Helleborus had larger leaves and longer leaf petioles than plants of the cultivar HGC Jericho.
- 3. Plants of the new Helleborus were more freely flowering than plants of the cultivar HGC Jericho.
- 4. Plants of the new Helleborus had longer peduncles than plants of the cultivar HGC Jericho.
The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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 actual colors of the new Helleborus.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘HGC Green Corsican’.
The photograph at the bottom of the sheet is a close-up view of a typical flower of ‘HGC Green Corsican’.
The aforementioned photographs, following observations and measurements describe plants grown in Glandorf, Germany, in a glass-covered greenhouse and under commercial production practices during the winter. Plants were grown in 15-cm containers and were about six months old when the photographs and description were taken. During the production of the plants, day temperatures were about 18° C. and night temperatures were about 14° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
