ABSTRACT:

BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Senecio genus plant named ‘Sunsenedibu’. ‘Sunsenedibu’ is a distinct and unique variety, which is a dome-shaped plant of high height with abundant branching, deep violet flowers, and long blooming term.
There are many varieties of
Senecio L. Senecio cruentus
is well known as Cineraria and cultivated in the world. There are many cultivated varieties having flowers of a single color of white, pink red, blue or violet. Some varieties have marginal variegation with off color parts.
The female parent used in the crossing of ‘Sunsenedibu’ is a cultivar,
Senecio cruentus
, ‘Jupiter Blue’ (not patented in the United States). ‘Jupiter Blue’ is a compact dome-shaped plant, 18.5 cm high. The stem is thick, 8.3 mm in diameter, with anthocyanin coloration. The leaf is of a serrated heart form and grayish yellow green having a medium size, 12.0 cm long and 12.5 cm wide. The flower is single flowered and has vivid blue petals with deep blue disk flowers and no marginal variegation. ‘Jupiter Blue’ has some scent.
The pollen parent used in the crossing of ‘Sunsenedibu’ is
Senecio heritierii
(not patented in the United States), which was introduced from nurseries in England.
Senecio heritierii
is a high and dome-shaped plant, 26 cm high abundant branching. The stem is 5.1 mm in diameter, with no anthocyanin coloration. The leaf is of a serrated heart form and light yellowish green. Leaf size is small, 5.5 cm long and 6.3 cm wide. The flower is single flowered, having strong purple petals with vague white parts and strong reddish purple disk flowers.
Senecio heritierii
has no scent.
Controlled crossing with
Senecio cruentus
‘Jupiter Blue’ and
Senecio heritierii
was conducted at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan in January 1995. Seedlings from this crossing were grown since July 1995. One variety was selected in January 1996 among them in view of flower color and early blooming. After multiplication by tissue culture, the botanical characteristics of the selected variety were examined and tested in potting, using parent varieties, as well as ‘Miss Yokohama’, and ‘Midget’, for comparison since July 1996. As a result, it is confirmed that this selected variety met our criteria of being uniform and stable in its characteristics.
Then this new variety of Senecio genus plant was named ‘Sunsenedibu’ (
Senecio cruentus×Senecio heritierii
).
Senecio cruentus
‘Jupiter Blue’ and
Senecio heritierii
are presently maintained at Hakushu-cho, Kitakoma-gun, Yamanashi-ken, Japan.
In the following descriptions, the color-coding is in accordance with The Horticultural Colour Chart of The Royal Horticultural Society, London, England (R.H.S. Colour Chart), and a color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart).
