Claims
It is claimed:
1. A new and distinct Catharanthus plant named `Suncatso 23` as
illustrated and described.
Description
Botanical designation: Catharanthus roseus.
Cultivar denomination: `SUNCATSO 23`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct Catharanthus
plant, botanically known as Catharanthus roseus and hereinafter
referred to by the cultivar name `Suncatso 23`.
The new Catharanthus plant is a product of a planned breeding
program conducted by the Inventor in Higashiomi, Shiga, Japan. The
objective of the breeding program is to develop new vigorous and
freely branching Catharanthus plants with numerous double-type
flowers.
The new Catharanthus plant originated from a cross-pollination
conducted by the Inventor in Higashiomi, Shiga, Japan in September,
2011 of a proprietary selection of Catharanthus roseus identified
as code designation S22-P-30, not patented, as the female, or seed,
parent with a proprietary selection of Catharanthus roseus
identified as code designation SIR22-10, not patented, as the male,
or pollen, parent. The new Catharanthus plant was discovered and
selected by the Inventor as a single flowering plant from within
the progeny of the stated cross-pollination in a controlled
greenhouse environment in Higashiomi, Shiga, Japan in September,
2013.
Asexual reproduction of the new Catharanthus plant by vegetative
tip cuttings in a controlled greenhouse environment in Higashiomi,
Shiga, Japan since December, 2013, has shown that the unique
features of this new Catharanthus plant are stable and reproduced
true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Catharanthus have not been observed under all
possible combinations of environmental conditions and cultural
practices. The phenotype may vary somewhat with variations in
environmental conditions such as temperature and light intensity
without, however, any variance in genotype.
The following traits have been repeatedly observed and are
determined to be the unique characteristics of `Suncatso 23`. These
characteristics in combination distinguish `Suncatso 23` as a new
and distinct Catharanthus plant: 1. Upright to outwardly spreading
and mounding plant habit. 2. Vigorous growth habit. 3. Freely basal
branching habit. 4. Freely flowering habit. 5. Long flowering
period. 6. Double-type flowers that are purple violet in color. 7.
Good garden performance.
Plants of the new Catharanthus can be compared to plants of the
female parent selection. Plants of the new Catharanthus differ
primarily from plants of the female parent selection in flower
color as plants of the female parent selection have white-colored
flowers.
Plants of the new Catharanthus can be compared to plants of the
male parent selection. Plants of the new Catharanthus differ
primarily from plants of the male parent selection in flower form
as plants of the male parent selection have single-type
flowers.
Plants of the new Catharanthus can be compared to plants of the
Catharanthus roseus `Suncatha 2335`, disclosed in a U.S. Plant
patent application Ser. No. 14/121,583. In side-by-side
comparisons, plants of the new Catharanthus differ from plants of
`Suncatha 2335` in the following characteristics: 1. Plants of the
new Catharanthus are not as broad as plants of `Suncatha 2335`. 2.
Plants of the new Catharanthus have thicker and lighter
green-colored stems than plants of `Suncatha 2335`. 3. Plants of
the new Catharanthus and `Suncatha 2335` differ in flower color as
plants of `Suncatha 2335` have flowers that are pink in color with
a distinct red purple-colored eye zone.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall
appearance of the new Catharanthus plant showing the colors as true
as it is reasonably possible to obtain in colored reproductions of
this type. Colors in the photographs may differ slightly from the
color values cited in the detailed botanical description which
accurately describe the colors of the new Catharanthus plant.
The photograph at the top of the sheet is a side perspective view
of a typical flowering plant of `Suncatso 23` grown in a
container.
The photograph at the bottom of the sheet is a close-up view of a
typical flowering plant of `Suncatso 23`.

temperatures averaged 25.degree. C. and night temperatures averaged
15.degree. C. Plants were seven months old when the photographs and
description were taken. In the following description, color
