Abstract

A new and distinct cultivar of Catharanthus plant named ‘Sunnichi Tahome’, characterized by its upright to outwardly spreading plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; long flowering period; relatively large white-colored flowers with red purple-colored centers; and good garden performance.

Description

Botanical designation: Catharanthus roseus.
Cultivar denomination: ‘SUNNICHI TAHOME’.
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 name ‘Sunnichi Tahome’.
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 freely branching and vigorous Catharanthus plants with upright to outwardly spreading plant habit and numerous attractive flowers.
The new Catharanthus plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in June, 2006 of a proprietary selection of Catharanthus roseus identified as code number Casp2-1, not patented, as the female, or seed, parent with a proprietary selection of Catharanthus roseus identified as code number Cacv10-1, 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 April, 2007.
Asexual reproduction of the new Catharanthus plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April, 2007, 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 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 ‘Sunnichi Tahome’. These characteristics in combination distinguish ‘Sunnichi Tahome’ as a new and distinct Catharanthus plant:
    • 1. Upright to outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely basal branching habit.
    • 4. Freely flowering habit.
    • 5. Long flowering period.
    • 6. Relatively large white-colored flowers with red purple-colored centers.
    • 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 petal color as plants of the female parent selection have pink-colored flower petals.
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 the following characteristics:
    • 1. Plants of the new Catharanthus are more upright than and not as trailing as plants of the male parent selection.
    • 2. Plants of the new Catharanthus and the male parent selection differ in flower color as plants of the male parent selection have rose pink-colored flowers.
Plants of the new Catharanthus can be compared to plants of the Catharanthus roseus ‘Sunnichihoho’, disclosed in U.S. Plant Pat. No. 20,541. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Catharanthus differed from plants of ‘Sunnichihoho’ in the following characteristics:
    • 1. Plants of the new Catharanthus were more upright than and not as trailing as plants of ‘Sunnichihoho’.
    • 2. Plants of the new Catharanthus were larger than plants of ‘Sunnichihoho’.
    • 3. Leaves of plants of the new Catharanthus had shorter leaves with rounded apices whereas leaves of plants of ‘Sunnichihoho’ were longer and had acute apices.
    • 4. Plants of the new Catharanthus and ‘Sunnichihoho’ differed slightly in flower color.
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 comprises a side perspective view of a typical flowering plant of ‘Sunnichi Tahome’ grown in a container.
The photograph at the bottom of the sheet comprises a close-up view of a typical flower of ‘Sunnichi Tahome’.
 DETAILED BOTANICAL DESCRIPTION
