Abstract

A new and distinct cultivar of Viola plant named ‘Sunviolemo’, characterized by its compact, mounding and trailing plant habit; freely branching habit; freely flowering habit; and pale yellow-colored flowers.

Description

Botanical designation: Viola cornuta.
Cultivar denomination: ‘Sunviolemo’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Viola, botanically known as Viola cornuta and hereinafter referred to by the name ‘Sunviolemo’.
The new Viola 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 compact Viola cultivars with attractive flower coloration.
The new Viola originated from a cross-pollination made by the Inventor in April, 2002, in Higashiomi, Shiga, Japan, of a proprietary selection of Viola cornuta identified as code number 01V-39-3, not patented, as the female, or seed, parent with a proprietary selection of Viola cornuta identified as code number 01 V-41-3, not patented, as the male, or pollen, parent. The new Viola 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.
Asexual reproduction of the new Viola by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since April, 2004, has shown that the unique features of this new Viola are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar Sunviolemo has 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 ‘Sunviolemo’. These characteristics in combination distinguish ‘Sunviolemo’ as a new and distinct cultivar of Viola:
    • 1. Compact, mounding and trailing plant habit.
    • 2. Freely branching habit.
    • 3. Freely flowering habit.
    • 4. Long flowering period.
    • 5. Pale yellow-colored flowers.
Compared to plants of the female parent selection, plants of the new Viola differ primarily in flower color as plants of the female parent selection have darker yellow-colored flowers.
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 white-colored flowers.
Plants of the new Viola can also be compared to plants of the Viola cornuta, ‘Sunvioki’, disclosed in U.S. Plant Pat. No. 16,138. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Viola and ‘Sunvioki’ differed in the following characteristics:
    • 1. Plants of the new Viola were narrower than plants of ‘Sunvioki’.
    • 2. Plants of the new Viola had shorter leaves than plants of ‘Sunvioki’.
    • 3. Plants of the new Viola had larger flowers than plants of ‘Sunvioki’.
    • 4. Plants of the new Viola and ‘Sunvioki’ differed in flower color.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new Viola, 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.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunviolemo’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Sunviolemo’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and following observations, measurements and values describe plants grown in Higashiomi, Shiga, Japan, under commercial practice during the autumn in an outdoor nursery with day temperatures averaging 10° C. and night temperatures averaging 5° C.
