Claims
It is claimed:
1. A new variety of Senecio plant named `Sunsenebabu`,
substantially as herein illustrated and described.
Description
Botanical classification: Senecio cruentus.times.Senecio
heritieri.
Varietal denomination: `Sunsenebabu`.
BACKGROUND OF THE VARIETY
The present invention relates to a new variety of Senecio plant,
which originated from the crossing of the cultivar `Extra Blue`
(unpatented) as the female parent with a variety of Senecio
heritieri as the male parent.
There are many varieties in Senecio L. and Senecio cruentus, well
known as Senecio, cultivated in the world. There are many
cultivated varieties with capitula of a single color of white, pink
red, blue or violet. Some varieties have marginal variegation with
off color parts.
The female parent `Extra Blue` used in the crossing that produced
`Sunsenebabu` is a cultivar of Senecio cruentus. It is early
flowering variety having dwarf and mounding shape with large
leaves. It has small single capitula, the ray florets having a
vivid purple color. The seed of `Extra Blue` is commercially
available.
The male parent Senecio heritieri used in the crossing that
produced `Sunsenebabu` is a cultivar having a high and dome-shaped
growth habit with abundant branching and small leaves. It has small
single capitula, the ray florets having strong purple with vague
white center coloration. Senecio heritieri, introduced from
nurseries in England, has no variety name and, to Applicant's
knowledge, is neither patented nor sold in the United States.
In January 1996, crossing of `Extra Blue` as the female parent and
Senecio heritieri as the male parent was conducted at Hakushu-cho,
Kitakoma-gun, Yamanashi-ken, Japan. The seedlings obtained from
that crossing were grown in pots in glasshouses and evaluated from
July 1996. One seedling was selected in view of its growth habit,
flower color and flowering time in December 1996. That seedling was
propagated by cutting and grown in pots. A trial was carred out in
pots from July 1999, at Hakushu-cho, Kitakoma-gun, Yamanashi-ken,
Japan. The botanical characteristics of that plant were then
examined, using similar varieties `Sunsenebu` (U.S. Plant Pat. No.
12,104) and `Miss Yokohama` (unpatented) for comparison. As a
result, it was concluded that this Senecio plant is distinguishable
from any other variety, whose existence is known to us, and is
uniform and stable in its characteristics. The new variety of
Senecio plant was named `Sunsenebabu`.
The new variety was first asexually reproduced by cuttings in
Hakushu-cho, Kitakoma-gun, Jamanashi, Japan.
In the following description, the color-coding is in accordance
with The Horticultural Colour Chart of The Royal Horticultural
Society, London, England (R.H.S.).
SUMMARY OF THE VARIETY
This new variety is unlike any Senecio commercially available known
to the inventor as evidenced by the following unique combinations
of characteristics. 1. Semi-dwarf, obconical plant shape having
abundant branching with small leaves. 2. The capitula are single
and small. The ray floret color is vivid violet (near R.H.S. 94A).
The disc floret color is brilliant violet (near R.H.S. 68D). 3.
Blooming time is early, and flowering duration is long. 4. Low
fertility.
The new variety `Sunsenebabu` differs from the similar variety
`Sunsenebu` in the following points. 1. The plant size of
`Sunsenebabu` is smaller than that of `Sunsenebu`. 2. The capitulum
diameter of `Sunsenebabu` is smaller than that of `Sunsenebu`. 3.
The disc floret color of `Sunsenebabu` is brilliant violet (near
R.H.S. 89D), while that of `Sunsenebu` is deep violet (near R.H.S.
93A). 4. The peduncle length of `Sunsenebabu` is shorter than that
of `Sunsenebu`. 5. The blooming time of `Sunsenebabu` is earlier
than that of `Sunsenebu`.
The new variety `Sunsenebabu` differs from the similar variety
`Miss Yokohama` in the following points. 1. The plant height of
`Sunsenebabu` is higher than that of `Miss Yokohama`. 2. The number
of the branches of `Sunsenebabu` is more than that of `Miss
Yokohama`. 3. The leaf of `Sunsenebabu` is smaller than that of
`Miss Yokohama`. 4. The disc floret color of `Sunsenebabu` is
brilliant violet (near R.H.S. 89D) while that of `Miss Yokohama` is
vivid violet (near R.H.S. 96A). 5. The blooming time of
`Sunsenebabu` is earlier than that of `Miss Yokohama`. 6. The
flowering duration of `Sunsenebabu` is longer than that of `Miss
Yokohama`.
This new variety of Senecio Plant `Sunsenebabu` was asexually
reproduced by the use of cuttings at Hakushu-cho, Kitakoma-gun,
Yamanashi-ken, Japan, and homogeneity and stability thereof were
confirmed. The instant plant retains its distinctive
characteristics and reproduces true to type in successive
generations.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The depicted plants had been reproduced by the use of cuttings and
were photographed during January 2003 while growing outdoors in 12
cm pots at an age of approximately 5 months at Yokaichi-shi,
Shiga-ken, Japan.
FIG. 1 illustrates a typical plant of the new variety of Senecio
plant `Sunsenebabu` growing in a pot.
FIG. 2 illustrates a close-up view of typical capitula of the new
variety of Senecio plant `Sunsenebabu`.
