Abstract

A new and distinct cultivar of Senecio plant named ‘Sunsenehobume’, characterized by its upright and uniformly mounded plant habit; freely branching growth habit; freely flowering habit; and large daisy-type inflorescences with white-colored ray florets with light purple violet-colored apices and darker violet-colored disc florets.

Description

Botanical designation: Senecio cruentus.
Cultivar denomination: ‘SUNSENEHOBUME’.
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 ‘Sunsenehobume’.
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 and uniformly mounding Senecio plants with numerous attractive and large inflorescences.
The new Senecio plant originated from a cross pollination conducted by the Inventor in March, 2008 of a proprietary selection of Senecio cruentus identified as code number 07-21, not patented, as the female, or seed, parent with a proprietary selection of Senecio cruentus identified as code number 07-18, 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, 2010.
Asexual reproduction of the new Senecio plant by terminal cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since February, 2010 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 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 ‘Sunsenehobume’. These characteristics in combination distinguish ‘Sunsenehobume’ as a new and distinct Senecio plant:
    • 1. Upright and uniformly mounded plant habit.
    • 2. Freely branching growth habit.
    • 3. Freely flowering habit.
    • 4. Large daisy-type inflorescences with white-colored ray florets with light purple violet-colored apices and darker violet-colored disc florets.
Plants of the new Senecio can be compared to plants of the female parent selection. Plants of the new Senecio differ from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Senecio are more freely branching than plants of the female parent selection.
    • 2. Plants of the new Senecio have larger inflorescences than plants of the female parent selection.
    • 3. Plants of the new Senecio and the female parent selection differ in ray floret color as plants of the female parent selection have yellowish 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 from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Senecio have larger inflorescences than plants of the male parent selection.
    • 2. Plants of the new Senecio and the male parent selection differ in ray floret color as plants of the male parent selection have pale pink-colored ray florets.
Plants of the new Senecio can be compared to plants of Senecio cruentus×Senecio heritieri ‘Sunsenesopi’, disclosed in U.S. Plant Pat. No. 19,199. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Senecio differed from plants of ‘Sunsenesopi’ in the following characteristics:
    • 1. Plants of the new Senecio were larger than and not as upright as plants of ‘Sunsenesopi’.
    • 2. Plants of the new Senecio had larger and darker green-colored leaves than plants of ‘Sunsenesopi’.
    • 3. Plants of the new Senecio were more freely flowering than plants of ‘Sunsenesopi’.
    • 4. Plants of the new Senecio had larger inflorescences than plants of ‘Sunsenesopi’.
    • 5. Plants of the new Senecio and ‘Sunsenesopi’ differed in ray floret color as plants of ‘Sunsenesopi’ had light pink-colored ray florets.
    • 6. Plants of the new Senecio and ‘Sunsenesopi’ differed in disc floret color as plants of ‘Sunsenesopi’ had light violet to white-colored disc florets.
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 comprises a side perspective view of a typical flowering plant of ‘Sunsenehobume’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunsenehobume’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs, following observations and measurements describe plants grown during the winter and early spring in 15-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices which approximate those generally used in 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 six months old when the photographs and 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.
