Abstract

A new and distinct cultivar of Catharanthus plant named ‘Suncatfe 291’, characterized by its compact, semi-upright and uniformly mounding plant habit; vigorous growth habit; freely basal branching habit; freely flowering habit; long flowering period; relatively small star-shaped light red purple-colored flowers with dark red purple-colored centers; and good garden performance.

Description

Botanical designation: Catharanthus roseus.

Cultivar denomination: ‘SUNCATFE 291’.

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 ‘Suncatfe 291’.

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 compact and freely branching Catharanthus plants with numerous small attractive flowers.

The new Catharanthus plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in September, 2013 of a proprietary selection of Catharanthus roseus identified as code designation FS8239, not patented, as the female, or seed, parent with a proprietary selection of Catharanthus roseus identified as code designation VP8507, 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, 2015.

Asexual reproduction of the new Catharanthus plant by vegetative tip cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since December, 2015, 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 ‘Suncatfe 291’. These characteristics in combination distinguish ‘Suncatfe 291’ as a new and distinct Catharanthus plant:

- 1. Compact, semi-upright and uniformly mounding plant habit.
- 2. Vigorous growth habit.
- 3. Freely basal branching habit.
- 4. Freely flowering habit.
- 5. Long flowering period.
- 6. Relatively small star-shaped light red purple-colored flowers with dark 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 color as plants of the female parent selection have light pink-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 the following characteristics:

- 1. Plants of the new Catharanthus have smaller flowers than 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 light purple-colored flowers.

Plants of the new Catharanthus can be compared to plants of the Catharanthus roseus ‘Suncatha 2439’, disclosed in U.S. Plant Pat. No. 27,477. In side-by-side comparisons, plants of the new Catharanthus differ from plants of ‘Suncatha 2439’ in the following characteristics:

- 1. Plants of the new Catharanthus are shorter and narrower than plants of ‘Suncatha 2439’.
- 2. Plants of the new Catharanthus have thicker stems than plants of ‘Suncatha 2439’.
- 3. Plants of the new Catharanthus and ‘Suncatha 2439’ differ in flower color as plants of ‘Suncatha 2439’ have flowers that are dark red purple in 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 is a side perspective view of a typical flowering plant of ‘Suncatfe 291’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Suncatfe 291’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late summer and early autumn in 20-cm containers in an outdoor nursery in Higashiomi, Shiga, Japan and under cultural practices typical of commercial production. During the production of the plants, day temperatures averaged 25° C. and night temperatures averaged 15° C. Plants were four months old when the photographs were taken and five months old when the description was taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
