Description

BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of Senecio genus plant named ‘Sunsenere’. ‘Sunsenere’ is a distinct and unique variety, which is a dome-shaped plant of high height with abundant branching, vivid reddish purple flowers, and a long blooming term.
There are many varieties in Senecio L. Senecio cruentus is well known as ‘Cineraria’ and cultivated in the world. There are many cultivated varieties with 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 ‘Sunsenere’ is a cultivar, Senecio cruentus, ‘Jupiter Crimson’ (not patented in the United States), which is a compact, dome-shaped plant, 17 cm in height. The stems are thick, 8.5 mm in diameter, with anthocyanin coloration. The leaf is of a serrated heart form and moderate yellowish green. The leaf size is medium, 12.5 cm long and 13.5 cm wide. The flower is single flowered and has strong purplish red petals with moderate purplish red disk flowers having no marginal variegation. ‘Jupiter Crimson’ has some scent.
The pollen parent used in the crossing of ‘Sunsenere’ is Senecio heritierii (having no variety name; not patented or sold in the United States), which was introduced from nurseries in England. Senecio heritierii is a high and dome-shaped plant, 26 cm in height with abundant branching. The stems are 5.1 mm in diameter, with no anthocyanin coloration. The leaf is in a serrated heart form and light yellowish green. The leaf is small, 5.5 cm long and 6.3 cm wide. Flowers are single flowered, having strong purple petals with vague white parts and strong reddish purple disk flowers. Senecio heritierii has no scent.
The controlled crossing with Senecio cruentus ‘Jupiter Crimson’ and Senecio heritierii was first conducted at Hakusho-cho, Kitokoma-gun, Yamanashi-ken, Japan in January 1995. Seedlings from this crossing were grown since July 1995. The new 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 new variety were examined and tested in potting, using parent varieties and ‘Miss Yokohama’ and ‘Midget’ (both not patented in he United States) 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 ‘Sunsenere’ (Senecio cruentus×Senecio heritierii).
Senecio cruentus, ‘Jupiter Crimson’, and Senecio heritierii are presently maintained at the Hakusho-cho, Kitokoma-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). In some instances, the color-coding based on color charts from The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart) is also added for reference.

SUMMARY OF THE VARIETY
‘Sunsenere’ is a dome-shaped plant of high height (average height of 25 cm in the blooming period). There is a branch from every node and branching is abundant, i.e. 9 to 11 branches. The stem is 5.0 mm in diameter with anthocyanin coloration and few pubescences.
The leaves are small, 8.6 cm long and 10.3 cm wide. The leaves are shaped in a serrated heart form with a swollen basal part, which is notched at where the basal part of the blade attaches to the petiole. The leaf color is moderate yellowish green, with no anthocyanin coloration on reverse side. Pubescence on both sides of leaf is dense. The petiole is 9.0 cm long and 3.2 mm in diameter.
The new variety has large flower clusters which are high and uneven in shape (i.e. the locations of the individual flowers forming the cluster are uneven or not flat). A flower cluster means a gathering of heads in a plant of the new variety. A head is a flower consisting of a disk and a plurality of petals, i.e. ray flowers. The flower is single flowered with no marginal variegation. The corolla has a flat transected shape (i.e. when the corolla opens, petals are flat when viewed from the side). The flower is 6.4 cm in diameter, while the disk flower is 1.3 cm in diameter. The petal is 2.6 cm long and 0.8 cm wide. Before blooming, the color of the petal is vivid reddish purple (R.H.S.C.C. No. 74A), while the color of the disk is deep reddish purple (R.H.S.C.C. No. 71B). One flower has 15-16 ray flowers and 130 disk flowers. A ray flower has a pistil and a stamen formed by 5 connate anthers with separated filaments. A disk flower is tubular and has a pistil, but no stamen. 88 flowers are in a flower cluster. The degree of recurvature of calyx is 1.2 mm. The calyx is flat and has no anthocyanin coloration. Pedicel is 3.3 cm long and 1.2 mm in diameter. The flowers have some scent.
Blooming period is early and blooming term is long. After cutting in July, flowers begin to bloom at the end of November or in the first 10 days of December in Hakushu-cho, Kitakomer-gun, Yamanashi-ken, Japan. The blooming continues from December to May, if under appropriate control. Around a temperature of 15° C., the individual bloom lasts 2 weeks. The flower buds grow one after another from the axil. The flower is not self-cleaning because petals remain attached in a wilted and dry state as the flower fully matures.
The new variety has moderate cold hardiness and resistance to heat. The new variety does not die at aroung 0° C., but when frost occurs the cells can be necrosed resulting in the death of the plant. Usually, Senecio cruentus has a tendency of slightly reduced growth in a hot season, whereas the new variety has no problem in growing in the hot season.
The fertility of the new variety is low. Generally, Senecio genus plants have high fertility (i.e. bear many seeds per flower). In contrast, ‘Sunsenere’ bears no seed or very few seeds per flower. When no seed is formed, there is a part corresponding to a seed coat, which remains in an immature state, i.e. without embryo and endosperm inside the immature seed coat.
The new variety, ‘Sunsenere’, differs from similar varieties, ‘Miss Yokohama’ and ‘Midget’, of the Senecio genus and from parent varieties Senecio heritierii and ‘Juptier Crimson’ in the following points.
1. ‘Sunsenere’ is a high type plant, 25 cm in height. ‘Miss Yokohama’ is a compact type plant, 19 cm in height. ‘Midget’ is a compact type. plant, 14 cm in height. The pollen parent Senecio heritierii is a semi-compact type plant, 26 cm in height and female parent ‘Jupiter Crimson’ is a compact type plant, 17 cm in height.
2. The flower of ‘Sunsenere’ has vivid reddish purple petals, deep reddish purple disk flowers and no marginal variegation. That of ‘Miss Yokohama’ has vivid violet petals, deep violet disk flowers and white marginal part. That of ‘Midget’ has vivid reddish purple petals, strong reddish purple disk flowers and no marginal variegation. That of female parent ‘Jupiter Crimson’ has strong purplish red petals, moderate purplish red disk flowers and no marginal variegation. That of pollen parent Senecio heritierii has strong purple petals, strong reddish purple disk flower and white marginal part.
3. The leaves of ‘Sunsenere’ are shorter than that of ‘Miss Yokohama’ or ‘Midget’. The petiole length of ‘Sunsenere’ is longer than that of ‘Miss Yokohama’ or ‘Midget’.
4. ‘Sunsenere’ has fewer pubescence of stems than that of ‘Miss Yokohama’ or ‘Midget’.
5. The blooming term of ‘Sunsenere’ is longer than that of ‘Miss Yokohama’ or ‘Midget’.
6. The fertility of ‘Sunsenere’ is lower than that of ‘Miss Yokohama’ or ‘Midget’.
The plant height, flower color and leaf size are most distinctive characteristics of this new variety, ‘Sunsenere’.
