Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCALCHSTM’.

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 ‘USCALCHSTM’.

The new Calibrachoa plant is a naturally-occurring whole plant mutation of ‘USCAL91001’, disclosed in U.S. Plant Pat. No. 23,232. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant within a population of plants of ‘USCAL91001’ in a controlled greenhouse environment in Gensingen, Germany in July, 2012. The selection of the new Calibrachoa plant was based on its unique combination of flower color and flower color pattern.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Gensingen, Germany since August, 2012 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘USCALCHSTM’. These characteristics in combination distinguish ‘USCALCHSTM’ as a new and distinct Calibrachoa plant:

    • 1. Compact, upright to outwardly spreading and mounding to eventually trailing plant habit.
    • 2. Vigorous growth habit.
    • 3. Freely branching habit; dense and bushy appearance.
    • 4. Freely flowering habit.
    • 5. Bright yellow-colored petals with red purple-colored speckles and splotches forming a star-shaped pattern.
    • 6. Good garden performance.

The new Calibrachoa plant can be compared to plants of the mutation parent, ‘USCAL91001’. Plants of the new Calibrachoa differ primarily from plants of ‘USCAL91001’ in flower color as plants of ‘USCAL91001’ have red purple-colored flowers with yellow-colored star-shaped pattern.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘USCAL23101’, disclosed in U.S. Plant Pat. No. 27,010. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCAL23101’ in flower color as plants of ‘USCAL23101’ had solid cherry red-colored flowers.

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 bottom of the sheet is a side perspective view of a typical flowering plant of ‘USCALCHSTM’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘USCALCHSTM’.

 DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the late spring in 10-cm containers in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures averaged 24° C., night temperatures averaged 16° C. and light levels ranged from 7,000 to 10,000 foot-candles. Plants were pinched one time and were nine weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
