ABSTRACT:
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Senecio plant named ‘Sunsenebu’. ‘Sunsenebu’ is a distinct and unique variety, which displays a tall dome-shaped growth habit with abundant branching, vivid violet flowers, and a long blooming period.
There are many varieties in
Senecio L. Senecio cruentus
commonly is known as Cineraria and is cultivated in many parts of the world. There are many cultivated varieties having a single flower color of white, pink, red, blue or violet. Some varieties have marginal color variegation.
The female parent used in the crossing of ‘Sunsenebu’ is the,
Senecio cruentus
, ‘Jupiter Blue’ variety (non-patented in the United States and not commercially available in the United States). ‘Jupiter Blue’ is a compact dome-shaped plant having a height of approximately, 18.5 cm. The stems are thick, and 8.3 mm in diameter with anthocyanin coloration. The leaves are of a serrated heart-shaped form and are grayish yellow green in coloration. The leaf size is medium, 12.0 cm in length and 12.5 cm in width. The flower is single and has vivid blue petals with a deep blue flower disk and no marginal variegation. ‘Jupiter Blue’ has some fragrance.
The pollen parent used in the crossing of ‘Sunsenebu’ is an unnamed variety of
Senecio heritierii
(non-patented in the United States and not commercially available in the United States), which was introduced from nursery in England.
Senecio heritierii
is recognized to be a tall dome-shaped plant that is approximately 26 cm in height with abundant branching. Stems are 5.1 mm in diameter with no anthocyanin coloration. The leaves are serrated heart-shaped and are light yellowish green in coloration. The leaf size is small, 5.5 cm in length and 6.3 cm in width. Flowers are single with strong purple petals with some white parts and strong reddish purple disk flowers.
Senecio heritierii
has no fragrance.
The controlled crossing with
Senecio cruentus
‘Jupiter Blue’ and
Senecio heritierii
was conducted at the Hakushu Research Center located at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan in January 1995. Seedlings from this crossing were produced. The new variety of the present invention was selected in January 1996 in view of the flower coloration and early blooming. After asexual propagation by tissue culture and the use of cuttings at the same location, the botanical characteristics of the selected variety were examined and were tested using parental varieties and the ‘Miss Yokohama’, and ‘Midget’ varieties, for comparative purposes beginning in July 1996. As a result, it is confirmed that this selected variety of the present invention is distinctive and uniform and stable in its characteristics.
The new variety of Senecio genus plant was named ‘Sunsenebu’ and is botanically classified (
Senecio cruentus×Senecio heritierii
).
In the following description, the color-coding is in accordance with the R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color chart based on The Japan Color Standard for Horticultural Plants (J.H.S. Color Chart) is also added for reference.
