Botanical designation: Senecio cruentus.
Cultivar denomination: ‘SENE GOSIGORE’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Senecio plant, botanically known as Senecio cruentus, and hereinafter referred to by the name ‘Sene Gosigore’.
The new Senecio plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new upright, uniformly mounding and vigorous Senecio plants with a freely-branching habit and numerous attractive inflorescences.
The new Senecio plant originated from a cross pollination conducted by the Inventor in March, 2012 of a proprietary selection of Senecio cruentus identified as code number S10-97E1, not patented, as the female, or seed, parent with a proprietary selection of Senecio cruentus identified as code number S10-56-1, not patented, as the male, or pollen, parent. The new Senecio plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in February, 2013.
Asexual reproduction of the new Senecio plant by terminal cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since October, 2014 has shown that the unique features of this new Senecio plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Senecio 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 ‘Sene Gosigore’. These characteristics in combination distinguish ‘Sene Gosigore’ as a new and distinct Senecio plant:
- 1. Upright and uniformly mounded plant habit.
- 2. Vigorous growth habit.
- 3. Freely branching habit.
- 4. Freely flowering habit.
- 5. Daisy-type inflorescences with ray florets that are white in color and disc florets that are violet blue in color.
Plants of the new Senecio can be compared to plants of the female parent selection. Plants of the new Senecio differ primarily from plants of the female parent selection in ray floret color as plants of the new Senecio have white-colored ray florets whereas plants of the female parent selection have blue and white-colored ray florets.
Plants of the new Senecio can be compared to plants of the male parent selection. Plants of the new Senecio differ primarily from plants of the male parent selection in ray floret color as plants of the new Senecio have white-colored ray florets whereas plants of the male parent selection have blue-colored ray florets.
Plants of the new Senecio can also be compared to plants of Senecio cruentus x Senecio heritieri ‘Sunsenelibubi’, disclosed in U.S. Plant Pat. No. 20,191. In side-by-side comparisons, plants of the new Senecio differ from plants of ‘Sunsenelibubi’ in the following characteristics:
- 1. Plants of the new Senecio are not as upright as plants of ‘Sunsenelibubi’.
- 2. Plants of the new Senecio have larger leaves than plants of ‘Sunsenelibubi’.
- 3. Plants of the new Senecio and ‘Sunsenelibubi’ differ in ray floret color as plants of the new Senecio have white-colored ray florets whereas plants of ‘Sunsenelibubi’ have violet and white bi-colored ray florets.
- 4. Plants of the new Senecio have shorter peduncles than plants of ‘Sunsenelibubi’.
- 5. Plants of the new Senecio and ‘Sunsenelibubi’ differ in peduncle color as plants of the new Senecio have green-colored peduncles whereas plants of ‘Sunsenelibubi’ have greyed purple-colored peduncles.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Senecio 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 Senecio plant.
The photograph at the top of the sheet is a side perspective view of a typical flowering plant of ‘Sene Gosigore’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sene Gosigore’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown during the winter and spring in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial Senecio production. During the production of the plants, day temperatures averaged 10° C. and night temperatures averaged 5° C. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time. Plants were five months old when the photographs were taken and seven months old when the detailed description was 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.
