Description

Botanical classification: Senecio cruentus×Senecio heritieri.
Varietal denomination: cv. ‘Sunsenerabu’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct variety of Senecio plant named ‘Sunsenerabu’. ‘Sunsenerabu’ is a distinct and unique variety, a dome-shaped plant with abundant branching, light violet inflorescences, and a long blooming term.
There are many varieties of Senecio cruentus cultivated in the world, including varieties with inflorescences 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 ‘Sunsenerabu’ is a clone of our own breeding line, Senecio cruentus, ‘8S-84e’ (not patented in the United States), which is a compact, dome-shaped plant, approximately 16 cm in height. The stems are thick, approximately 8.0 mm in diameter, with no anthocyanin coloration. The leaf is in a serrated heart form with moderate yellow green coloration. The leaf size is medium, approximately 12.0 cm long, and approximately 12.5 cm wide. The capitulum is single flowered and has white ray florets with white disc florets having no marginal variegation. ‘8S-84e’ has some scent.
The pollen parent used in the crossing of ‘Sunsenerabu’ is our breeding line, Senecio heritieri (an unnamed plant; not patented or sold in the United States), which was first introduced from England. Senecio heritieri is a high, dome-shaped point, approximately 26 cm in height with abundant branching. Stems are approximately 5.1 mm in diameter, with no anthocyanin coloration. The leaf is in a serrated heart form and light yellowish green in coloration. The leaf size is small, approximately 5.5 cm long and approximately 6.3 cm wide. The capitulum is single flowered, having strong purple ray florets with vague white parts and strong reddish purple disc florets. Senecio heritieri has no scent.
The controlled crossing of a plant of Senecio cruentus ‘8S-84e’ and a plant of Senecio heritieri (unnamed) was conducted in Omori-cho, Yokaichi-shi, Shiga, Japan in February, 1999. Seedlings from this crossing have been grown since September, 1999. Four strains were selected in January 2000 in view of flower color and earliness of bloom. After multiplication by tissue culture, the botanical characteristics of the selected new strains were tested in pots starting in September 2000, using the varieties ‘Sunsenebu’ (U.S. Plant Pat. No. 12,104, issued Sep. 25, 2001), and ‘Miss Yokohama’ (not patented in the United States) for comparison.
One seedling was propagated by a cutting in Yokaich-shi, Shiga-ken, Japan. The new variety reproduces true to type in successive generations of asexual reproduction. This new variety of Senecio plant was named ‘Sunsenerabu’ (Senecio cruentus×Senecio heritieri).
The parent plants, Senecio cruentus, ‘8S-84e’, and Senecio heritieri (unnamed), are presently maintained at Shiga-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.).

SUMMARY OF THE NEW VARIETY
‘Sunsenerabu’ is a dome-shaped plant with an approximate height of 39.5 cm in the blooming period. There is a branch from every node and branching is abundant, i.e., approximately 9 to 11 branches. The stem is approximately 4.9 mm in diameter with light pubescence.
The leaves are small, approximately 7.6 cm long and approximately 9.2 cm wide. The leaves are shaped in a serrated heart form with a swollen basal part, which is notched where the basal part of the blade attaches to the petiole. The leaf color is strong yellow green, with no anthocyanin coloration on the reverse side. Pubescence on upper side of leaf is sparse and pubescence on the reverse side is dense. The petiole is approximately 9.2 cm long and approximately 3.2 mm in diameter.
The new variety has large inflorescence clusters, which are high and flat in shape (i.e., the individual capitula forming the cluster are flat). An inflorescence cluster means a gathering of capitula in a plant. The capitulum is a single inflorescence with marginal variegation and has an obscure border. The capitulum has a flat transected shape (i.e., when the capitulum opens, ray florets are flat when viewed from the side). The capitulum is approximately 7.4 cm in diameter, while the entire disc is approximately 1.3 cm in diameter. The ray floret is approximately 3.0 cm long and approximately 0.8 cm wide. The color of the ray floret is light violet (near R.H.S. 91A), while the color of the disc florets are violet (near R.H.S. 90B). One capitulum has approximately 13 ray florets and approximately 149 disc florets. A ray floret has a pistil, but no stamen. A disc floret is tubular and has a pistil and a stamen formed by 5 connate anthers with separated filaments. There are approximately 180 capitula per plant. The length of the phyllary is approximately 2.0 mm. The phyllary is flat and has no anthocyanin coloration. The pedicel is approximately 3.5 cm long and approximately 1.3 mm in diameter. The capitula have some scent.
After cutting in July, the new variety ‘Sunsenerabu’ flowers at the end of the January in Omori-cho, Yokaichi-shi, Shiga-ken, Japan. The blooming continues from January to May, if under appropriate control. At a temperature of around 15° C., the individual bloom lasts two weeks. The inflorescence buds grow one after another from the axil. The inflorescence is not self-cleaning because the ray florets remain attached in a wilted and dry state as they fully mature.
The new variety has moderate cold and heat tolerance. The new variety does not die at temperatures of around 0° C., but when frost occurs the cells can necrose resulting in the death of the plant. Usually, Senecio cruentus has a tendency of slightly reduced growth in the hot session, whereas the new variety has no problem growing in the hot season.
The fertility of the new variety is low. Generally, Senecio plants have high fertility (i.e., bear many seeds per flower). In contrast, ‘Sunsenerabu’ bears no seed or very few seeds per capitulum. 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.
The new variety, ‘Sunsenerabu’, differs from similar ‘Sececio’ varieties ‘Sunsenebu’ and ‘Miss Yokohama’ varieties and from the parental varieties Senecio heritieri (unnamed) and ‘8S-84e’ in the following points.
    • 1. ‘Sunsenerabu’ is taller than ‘Miss Yokohama’, Senecio heritieri (pollen parent) and ‘8S-84e’.
    • 2. The capitulum of ‘Sunsenerabu’ has light violet ray florets, strong violet disc florets and obscure marginal variegation. ‘Sunsenebu’ has vivid violet ray florets, deep violet disc florets and no marginal variegation. ‘Miss Yokohama’ has vivid violet ray florets, vivid violet disc florets and no marginal variegation. The female parent ‘8S-84e’ has white ray florets, white disc florets and no marginal variegation. The pollen parent Senecio heritieri (unnamed) has strong purple ray florets, strong reddish purple disc florets and white marginal part.
    • 3. The petiole length of ‘Sunsenerabu’ is longer than that of ‘Sunsenebu’ or ‘Miss Yokohama’.
    • 4. ‘Sunsenerabu’ has less stem pubescence than that of ‘Miss Yokohama’.
    • 5. The blooming period of ‘Sunsenerabu’ is longer than that of ‘Miss Yokohama’.
    • 6. The fertility of ‘Sunsenerabu’ is lower than that of ‘Miss Yokohama’.
The plant height and flower color are the most distinctive characteristics of this new variety, ‘Sunsenerabu’.
