Abstract: A new and distinct cultivar of Calibrachoa plant named `Sunbelflam`, characterized by its upright, outwardly spreading and mounding plant habit; vigorous growth habit; freely branching habit; freely flowering habit; long flowering period; dark pink-colored flowers with darker pink-colored centers and venation; and good weather tolerance.
Claim: It is claimed:

1. A new and distinct cultivar of Calibrachoa plant named `Sunbelflam`, as illustrated and described.
Description: Botanicaldesignation: Calibrachoa sp.

Cultivar denomination: `Sunbelflam`.


The present Invention relates to a new and distinct cultivar of Calibrachoa plant, botanically known as Calibrachoa sp., and hereinafter referred to by the cultivar name `Sunbelflam`.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new outwardly spreading Calibrachoas with large and attractive flowers.

The new Calibrachoa originated from a cross-pollination made by the Inventor in April, 2001, of a proprietary selection of Calibrachoa cornuta identified as code number 9P6, not patented, as the female, or seed, parent with a proprietaryselection of Calibrachoa cornuta identified as code number 9L2, not patented, as the male, or pollen, parent. The new Calibrachoa was selected as a single plant from the resulting progeny of the cross-pollination by the Inventor in a controlledenvironment in Higashiomi, Shiga, Japan.

Asexual reproduction of the new cultivar by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since September, 2003, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type insuccessive generations.


Plants of the cultivar Sunbelflam have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, anyvariance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Sunbelflam`. These characteristics in combination distinguish `Sunbelflam` as a new and distinct cultivar of Calibrachoa: 1. Upright,outwardly spreading and mounding plant habit. 2. Vigorous growth habit. 3. Freely branching habit. 4. Freely flowering habit. 5. Long flowering period. 6. Pink-colored flowers with darker pink-colored centers and venation. 7. Good weathertolerance; tolerant to rain and low and high temperatures.

Plants of the new Calibrachoa differ from plants of the female and male parent selections in flower size as plants of the new Calibrachoa have larger flowers than plants of the parent selections. In addition, plants of the new Calibrachoa andthe parent selections differ in flower color as plants of the female parent selection have red purple-colored flowers and plants of the male parent selection have light purple-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the cultivar Sunbelochipi, disclosed in U.S. Plant Pat. No. 10,355. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Calibrachoa had larger flowerswith more acute petal apices than plants of the cultivar Sunbelochipi. In addition, plants of the new Calibrachoa and the cultivar Sunbelochipi differed in flower color as plants of the cultivar Sunbelochipi had red purple-colored flowers.


The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of `Sunbelflam` grown in a container.

The photograph at the bottom of the sheet is a close-up view of typical flowers and leaves of `Sunbelflam`.


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. Plants grown in 15-cm containers for about fourmonths were used for the aforementioned photographs and following description. Plants were grown under conditions which closely approximate commercial production conditions during the spring in Higashiomi, Shiga, Japan in a polyethylene-coveredgreenhouse. During the production period, day temperatures were about C. and night temperatures were about C. Plants were pinched one time in the spring.
