Description

Botanical designation: Nemesia hybrida.

Cultivar denomination: ‘Wesneche’.

BACKGROUND OF THE INVENTION

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

The new Nemesia is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program is to create new compact Nemesia cultivars with uniform plant habit and attractive flower coloration.

The new Nemesia originated from a cross-pollination made by the Inventor in 2004 in Südlohn, Germany of a proprietary selection of Nemesia hybrida identified as code number 04P007, not patented, as the female, or seed, parent with a proprietary selection of Nemesia hybrida identified as code number 04P194, not patented, as the male, or pollen, parent. The new Nemesia 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 Südlohn, Germany in 2005.

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

SUMMARY OF THE INVENTION

The cultivar Wesneche has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘Wesneche’. These characteristics in combination distinguish ‘Wesneche’ as a new and distinct cultivar of Nemesia:

    • 1. Compact, upright and uniformly mounded growth habit.
    • 2. Freely branching and flowering plant habit.
    • 3. Durable dark green-colored leaves.
    • 4. Intense red-colored flowers.
    • 5. Good garden performance.

Plants of the new Nemesia differ from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Nemesia are more vigorous than plants of the female parent selection.
    • 2. Plants of the new Nemesia have stronger lateral branches than plants of the female parent selection.
    • 3. Plants of the new Nemesia have larger leaves than plants of the female parent selection.
    • 4. Plants of the new Nemesia and the female parent selection differ in flower color as plants of the female parent selection have yellow-colored flowers.

Plants of the new Nemesia differ from plants of the male parent selection in the following characteristics:

    • 1. Plants of the new Nemesia are more compact and less vigorous than plants of the male parent selection.
    • 2. Plants of the new Nemesia have smaller flowers than plants of the male parent selection.
    • 3. Plants of the new Nemesia and the male parent selection differ in flower color as plants of the male parent selection have orange red-colored flowers.

Plants of the new Nemesia can be compared to plants of the cultivar Nemhapri, disclosed in U.S. Plant Pat. No. 18,108. In side-by-side comparisons conducted by the Inventor in Südlohn, Germany, plants of the new Nemesia differed from plants of the cultivar Nemhapri in the following characteristics:

    • 1. Plants of the new Nemesia had stronger lateral branches than plants of the cultivar Nemhapri.
    • 2. Plants of the new Nemesia had larger leaves than plants of the cultivar Nemhapri.
    • 3. Plants of the new Nemesia had more open flowers than plants of the cultivar Nemhapri.
    • 4. Plants of the new Nemesia and the cultivar Nemhapri differed in flower color as plants of the cultivar Nemhapri had pink and orange-colored flowers.

Plants of the new Nemesia can be compared to plants of the cultivar Inuprasp, disclosed in U.S. Plant Pat. No. 17,978. In side-by-side comparisons conducted by the Inventor in Südlohn, Germany, plants of the new Nemesia differed from plants of the cultivar Inuprasp in the following characteristics:

    • 1. Plants of the new Nemesia had longer lateral branches than plants of the cultivar Inuprasp.
    • 2. Plants of the new Nemesia had longer leaves than plants of the cultivar Inuprasp.
    • 3. Plants of the new Nemesia had more open flowers than plants of the cultivar Inuprasp.
    • 4. Plants of the new Nemesia were more freely flowering than plants of the cultivar Inuprasp.
    • 5. Plants of the new Nemesia and the cultivar Inuprasp differed in flower color as plants of the cultivar Inuprasp had red purple-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Nemesia, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Nemesia. The photograph comprises a side perspective view of a typical flowering plant of ‘Wesneche’ grown in a container.
