Senecio genus plant named ‘Sunsenereba’

Abstract

Disclosed herein is a Senecio genus plant named ‘Sunsenereba’ which is a tall dome-shaped plant with abundant branching. There are very few pubescences on its stems. The leaf length of ‘Sunsenereba’ is shorter and the petiole is longer than that in other varieties of Senecio L. ‘Sunsenereba’ has no stipule. The flower cluster is large. The flower is single flowered having a wide white central part. The petal has a vivid purple tip and a white base. The disk flower is deep reddish purple. The blooming starts early and the blooming term is longer than Senecio cruentus. Flower buds grow one after another from axil. ‘Sunsenereba’ is distinguished from other varieties particularly by (A) being tall, dome-shaped with abundant branching, (B) having very sparse pubescences on its stems, (C) having short leaves and a long petiole, (D) having a large flower cluster, (E) having vivid reddish purple petals and deep reddish purple disk flowers, (F) having flowers with side white marginal parts, (G) having a long blooming term and (H) having low fertility.

Description

BACKGROUND OF THE VARIETY

The present invention relates to a new and distinct variety of Senecio genus plant named ‘Sunsenereba’, which is a relatively tall, dome-shaped plant with abundant branching, vivid reddish purple flowers having white marginal parts and a 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. Flowers of Senecio are of a solid 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 ‘Sunsenereba’ is a cultivar, Senecio cruentus, ‘Jupiter Pink-white’ (not patented in the United States). ‘Jupiter Pink-white’ is a compact, dome-shaped plant, 17.5 cm in height. the stem is thick, 8.0 mm in diameter, with anthocyanin coloration. The leaf is of a serrated heart form and moderate yellowish green. The leaf size is medium, 11.5 cm long and 12.5 cm wide. The flower is single flowered and has light pink petals with deep pink disk flowers and distinct white marginal parts. ‘Jupiter Pink-white’ has some scent.

The pollen parent used in the crossing of ‘Sunsenereba’ is Senecio heritierii (not patented in the United States), which was introduced from nurseries in England. Senecio heritierii is a tall, dome-shaped plant, 26 cm in height with 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. The leaf is small, 5.5 cm long and 6.3 cm wide. The flower is single flowered, has 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 Pink-white’ and Senecio heritierii was first conducted at Hakushu-cho, Kitokoma-gun, Yamanashi-ken, Japan in January 1995. Seedlings from this crossing were grown since July 1955. 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 parental varieties, as well as ‘Rouge Chigasaki’, ‘Miss Yokohama’, and ‘Midget’, for comparison since July 1996. As a result, it has been confirmed that this selected variety is uniform and stable in its characteristics.

This new variety of Senecio genus plant was named ‘Sunsenereba’ (Senecio cruentus×Senecio heritierii).

Senecio cruentus ‘Jupiter Pink-white’, and Senecio heritierii are presently maintained at Hakushu-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) and the color chart based on The Japan Color Standard for Horticultural Plant (J.H.S. Color Chart).

SUMMARY OF THE NEW VARIETY

‘Sunsenereba’ is a relatively tall, dome-shaped plant averaging 30.5 cm in height in the blooming period. It branches from every node and the branching is abundant. The stem is 4.2 mm in diameter, with anthocyanin coloration and sparse pubescences.

The leaf is small, 8.0 cm long and 9.3 cm wide. Its shape is in a serrated heart form with a swollen basal part, which is notched at where the basal part attaches to a petiole. The leaf is strong yellowish green, with light anthocyanin coloration on the reverse side. Pubescence on both sides of the leaf is dense. The petiole is 8.1 cm long and 2.8 mm in diameter.

The flower cluster is large, tall and uneven in shape (i.e. the locations of the heads in the flower cluster is uneven, i.e. irregular, and not flat). The term “flower cluster” refers to a gathering of the heads in a plant. A head or flower of ‘Sunsenereba’ contains a disk and a plurality of petals, i.e. ray flowers. A disk flower is tubular and has a pistil, but no stamen. A ray flower has a pistil and stamens formed by 5 anthers fused together with separated filaments. The flower is single flowered and has a white central part, which is an off color part at the base of the petal (the off color part is a white part of the flower forming a centrally located circular pattern). The diameter of the off color part is 3.4 cm (i.e. the diameter of the centrally located circular pattern is 3.4 cm) and the border of marginal variegation is fairly clear. The transected shape (i.e. the cross section of the corolla viewed from the side) of the corolla is fairly closed. In other words, when the corolla is open, the petals are slanted slightly upward when a side view of the cross section of the corolla is taken. The flower diameter is 6.7 cm. The petal is 2.9 cm long, 0.8 cm wide and vivid reddish purple. The disk flower is 1.1 cm in diameter and its color is deep reddish purple. One flower has 13 ray flowers and 127 disk flowers. A flower cluster has 97 flowers. The degree of recurvature of the calyx is 2.2 mm. The calyx is flat and has some anthocyanin coloration. The pedicel is 4.5 cm long and 1.2. mm in diameter. The flowers have some scent.

The blooming period is early and the blooming term is long. After cutting in July in Hakusho-cho, Kitakoma-gun, Yamanashi-ken, Japan, ‘Sunseneraba’ begins to bloom in the first 10 days of December. The plant continues to bloom from December to May under appropriate control. If the temperature is maintained around 15° C., individual blooms last about 2 weeks. Flower buds grow one after another from the axil (when an upper flower finished growing, a flower bud is generated from the next lower axil). The flowers are not self-cleaning, so petals remain attached in a wilted and dry state as a flower fully matures.

‘Sunsenereba’ has moderate cold hardiness and resistance to heat. It does not die at a temperature around 0° C. When frost occurs, its cells can be necrosed resulting in the death of ‘Sunsenereba’. Senecio cruentus usually slows down its growth slightly in a hot season. In comparison, ‘Sunsenereba’ has no problem in growing in the hot season.

Generally, Senecio varieties have high seed fertility, i.e. have many seeds per flower. However, the fertility of ‘Sunsenereba’ is low. The new variety has no seed or very few seeds per flower. When no seed is formed, there is a part corresponding to a seed coat and only the seed coat part remains in an immature state because there is no embryo and endosperm within the immature seed coat part.

The new variety of Senecio genus plant named ‘Sunsenereba’ differs from the similar varieties, ‘Rouge Chigasaki’, ‘Miss Yokohama’, and ‘Midget’, as well as the parental varieties, Senecio heritierii and ‘Jupiter Pink-white’, in the following botanical characteristics.

1. ‘Sunsenereba’ is a tall type plant, 30.5 cm in height. ‘Rouge Chigasaki’ is a compact type plant, 17.5 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. The female parent ‘Jupiter Pink-white’ is a compact type plant, 17.5 cm in height.

2. The flower of ‘Sunsenereba’ has petals with a vivid reddish purple tip and white base forming a central white part for the flower, and deep reddish purple disk flowers. That of ‘Rouge Chigasaki’ has deep red petals with white wide parts, and deep purplish red disk flowers. That of ‘Miss Yokohama’ has vivid violet petals with wide white parts, and deep violet disk flowers. That of ‘Midget’ has petals of a solid color, i.e. vivid reddish purple, with no marginal variegation, and deep reddish purple disk flowers. That of female parent ‘Jupiter Pink-white’ has deep purplish red petals with wide white parts, and moderate purplish red disk flowers. That of pollen parent Senecio heritierii has deep purple petals with narrow white parts, and deep reddish purple disk flowers.

3. The leaf of ‘Sunsenereba’ is shorter than that of ‘Rouge Chigasaki’, ‘Miss Yokohama’ or ‘Midget’. The petiole is longer than that of ‘Rouge Chigasaki’or ‘Midget’.

4. ‘Sunsenereba’ has fewer pubescence of stems then that of ‘Rouge Chigasaki’, ‘Miss Yokohama’ or ‘Midget’.

5. The blooming term of ‘Sunsenereba’ is longer than that of ‘Rouge Chigasaki’, ‘Miss Yokohama’ or ‘Midget’.

6. The fertility of ‘Sunsenereba’ is lower than that of ‘Rouge Chigasaki’, ‘Miss Yokohama’ or ‘Midget’.

The plant height, flower color and leaf size are the most distinctive characteristics of this new variety ‘Sunsenereba’.
