Description

Botanical designation: Nierembergia hybrida.

Cultivar denomination: ‘Sunnipariho’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nierembergia, botanically known as Nierembergia hybrida and hereinafter referred to by the name ‘Sunnipariho’.

The new Nierembergia is a product of a planned breeding program conducted by the Inventor in Shiga, Japan. The objective of the breeding program was to create new compact Nierembergia cultivars with attractive flower coloration.

The new Nierembergia originated from a cross-pollination made by the Inventor during the summer of 2003, in Shiga, Japan, of a proprietary selection of Nierembergia hybrida identified as code number NS1, not patented, as the female, or seed, parent with a proprietary selection of Nierembergia hybrida identified as code number NWL176, not patented, as the male, or pollen, parent. The new Nierembergia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Shiga, Japan.

Asexual reproduction of the new Nierembergia by vegetative cuttings in a controlled environment in Shiga, Japan since October, 2005, has shown that the unique features of this new Nierembergia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Sunnipariho 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 determine to be the unique characteristics of ‘Sunnipariho’. These characteristics in combination distinguish ‘Sunnipariho’ as a new and distinct cultivar of Nierembergia:

    • 1. Compact, upright and mounding plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit.
    • 4. Large white-colored flowers.
    • 5. Freely and continuous flowering habit.
    • 6. Good garden performance.

Compared to plants of the parent selections, plants of the new Nierembergia are more freely branching and flower earlier.

Plants of the new Nierembergia can also be compared to plants of the cultivar Sunniparisobu, disclosed in U.S. Plant Pat. No. 16,394. In side-by-side comparisons conducted in Shiga, Japan, plants of the new Nierembergia and the cultivar Sunniparisobu differed in the following characteristics:

    • 1. Plants of the new Nierembergia were shorter but more outwardly spreading than plants of the cultivar Sunniparisobu.
    • 2. Plants of the new Nierembergia had shorter internodes than plants of the cultivar Sunniparisobu.
    • 3. Plants of the new Nierembergia were more freely branching than plants of the cultivar Sunniparisobu.
    • 4. Plants of the new Nierembergia had narrower leaves than plants of the cultivar Sunniparisobu.
    • 5. Plants of the new Nierembergia flowered earlier than plants of the cultivar Sunniparisobu.
    • 6. Plants of the new Nierembergia had larger flowers than plants of the cultivar Sunniparisobu.
    • 7. Plants of the new Nierembergia and the cultivar Sunniparisobu differed in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Nierembergia, 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 Nierembergia.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunnipariho’ grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers of ‘Sunnipariho’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in Shiga, Japan, under commercial practice during the spring and summer in an outdoor nursery with day temperatures averaging 21° C. and night temperatures averaging 14° C. After planting, plants had been growing for about four months when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
