Abstract

A new and distinct cultivar of Viola plant named ‘Sunviopinho’, characterized by its semi-upright to outwardly spreading plant habit; vigorous growth habit; freely branching habit; freely flowering habit; and purple violet and white bi-colored flowers.

Description

Botanical designation: Viola cornuta.
Cultivar denomination: ‘SUNVIOPINHO’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Viola plant, botanically known as Viola cornuta and hereinafter referred to by the name ‘Sunviopinho’.
The new Viola plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program was to create new semi-upright to outwardly spreading and freely branching Viola cultivars with unique and attractive flower coloration.
The new Viola plant originated from a cross-pollination made by the Inventor in April, 2004, in Higashiomi, Shiga, Japan, of a proprietary selection of Viola cornuta identified as code number VF90-3, not patented, as the female, or seed, parent with a proprietary selection of Viola cornuta identified as code number VF193-5, not patented, as the male, or pollen, parent. The new Viola plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Higashiomi, Shiga, Japan in April, 2005.
Asexual reproduction of the new Viola plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since May, 2005, has shown that the unique features of this new Viola plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Viola have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Sunviopinho’. These characteristics in combination distinguish ‘Sunviopinho’ as a new and distinct cultivar of Viola:
    • 1. Semi-upright to outwardly spreading plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Freely flowering habit.
    • 5. Purple violet and white bi-colored flowers.
Compared to plants of the female parent selection, plants of the new Viola differ primarily in plant size as plants of the female parent selection are smaller than plants of the new Viola. In addition, plants of the new Viola are more freely branching than plants of the female parent selection.
Compared to plants of the male parent selection, plants of the new Viola differ primarily in flower color as plants of the male parent selection have light purple and light yellow-colored flowers. In addition, plants of the new Viola are larger than plants of the male parent selection.
Plants of the new Viola can also be compared to plants of the Viola cornuta ‘Sunviolabu’, disclosed in U.S. Plant Pat. No. 20,264. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Viola and ‘Sunviolabu’ differed in the following characteristics:
    • 1. Plants of the new Viola had shorter lateral branches than plants of ‘Sunviolabu’.
    • 2. Plants of the new Viola had larger leaves than plants of ‘Sunviolabu’.
    • 3. Plants of the new Viola and ‘Sunviolabu’ differed in flower color as plants of ‘Sunviolabu’ had light violet-colored flowers.
    • 4. Plants of the new Viola had shorter flower spurs than plants of ‘Sunviolabu’.
    • 5. Plants of the new Viola had shorter peduncles than plants of ‘Sunviolabu’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Viola 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 Viola plant.
The photograph at the top of the sheet comprises a top perspective view of a typical flowering plant of ‘Sunviopinho’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flowering plant of ‘Sunviopinho’.
 DETAILED BOTANICAL DESCRIPTION

Plants were five and four months old when the description and photographs, respectively, were taken.
