Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘SUNCALKULEMO’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp. and hereinafter referred to by the name ‘Suncalkulemo’.

The new Calibrachoa 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 trailing and freely-branching Calibrachoa plants with attractive and unique flower coloration.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Higashiomi, Shiga, Japan in April, 2005 of a proprietary selection of Calibrachoa sp. identified as code number CR1, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa sp. identified as code number CS1, not patented, as the male, or pollen, parent. The new Calibrachoa 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, 2006.

Asexual reproduction of the new Calibrachoa plant by vegetative cuttings in a controlled greenhouse environment in Higashiomi, Shiga, Japan since October, 2006, has shown that the unique features of this new Calibrachoa plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Calibrachoa 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 ‘Suncalkulemo’. These characteristics in combination distinguish ‘Suncalkulemo’ as a new and distinct cultivar of Calibrachoa:

    • 1. Outwardly spreading to trailing plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching and flowering plant habit.
    • 4. Early and long flowering period.
    • 5. Yellow-colored flowers.
    • 6. Good garden performance.

Plants of the new Calibrachoa can be compared to plants of the female parent selection. Plants of the new Calibrachoa differ primarily from plants of the female parent selection in the following characteristics:

    • 1. Plants of the new Calibrachoa are more trailing than plants of the female parent selection.
    • 2. Plants of the new Calibrachoa and the female parent selection differ in flower color as plants of the female parent selection have red-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in growth habit as plants of the new Calibrachoa are more trailing than plants of the male parent selection.

Plants of the new Calibrachoa can also be compared to plants of ‘Sunbelki’, disclosed in U.S. Plant Pat. No. 11,558. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa and ‘Sunbelki’ differed primarily in the following characteristics:

    • 1. Plants of the new Calibrachoa were more trailing than and not as upright as plants of ‘Sunbelki’.
    • 2. Plants of the new Calibrachoa were shorter than plants of ‘Sunbelki’.
    • 3. Plants of the new Calibrachoa were more freely branching than plants of ‘Sunbelki’.
    • 4. Leaves of plants of the new Calibrachoa were narrower than leaves of plants of ‘Sunbelki’.
    • 5. Flower corollas of plants of the new Calibrachoa did not have conspicuous venation whereas flower corollas of plants of ‘Sunbelki’ had conspicuous venation.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa 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 Calibrachoa plant.

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

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

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 15-cm containers in Higashiomi, Shiga, Japan, under commercial practice during the early summer in an outdoor nursery.
