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 ‘BBCAL91303’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Bonsall, Calif. The objective of the breeding program is to create new uniform and freely-branching Calibrachoa plants with unique and attractive flower colors and patterns and good garden performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Bonsall, Calif. on Aug. 12, 2016 of a proprietary seedling selection of Calibrachoa sp. identified as code number 16CB816-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number 16CB806-01, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and first selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Bonsall, Calif. on May 19, 2017.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, Calif. since Jun. 1, 2017 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 ‘BBCAL91303’. These characteristics in combination distinguish ‘BBCAL91303’ as a new and distinct Calibrachoa plant:

• • 1. Upright to outwardly spreading and mounding to eventually trailing plant habit.
  • 2. Vigorous growth habit.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Early and freely flowering habit.
  • 5. Red purple-colored flowers with bright yellow-colored centers.
  • 6. Good garden performance.

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 freely flowering than plants of the female parent selection.
  • 2. Plants of the new Calibrachoa and the female parent selection differ in flower color as flowers of plants of the new Calibrachoa are red purple in color with bright yellow-colored centers whereas flowers of plants of the female parent selection are purple and yellow bi-colored.
  • 3. Plants of the new Calibrachoa have good garden performance whereas plants of the female parent selection have poor garden performance.

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

• • 1. Plants of the new Calibrachoa are more freely flowering than plants of the male parent selection.
  • 2. Plants of the new Calibrachoa flower earlier than plants of the male parent selection.
  • 3. Plants of the new Calibrachoa have good garden performance whereas plants of the male parent selection have poor garden performance.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘USCALI11’, disclosed in U.S. Plant Pat. No. 14,968. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘USCALI11’ in the following characteristics:

• • 1. Plants of the new Calibrachoa are more outwardly spreading than and not as upright as plants of ‘USCALI11’.
  • 2. Plants of the new Calibrachoa and ‘USCALI11’ differ in flower color as flowers of plants of the new Calibrachoa are red purple in color with bright yellow-colored centers whereas flowers of plants of ‘USCALI11’ are light red purple in color.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa sp. ‘USCALI51’, disclosed in U.S. Plant Pat. No. 14,874. In side-by-side comparisons, plants of the new Calibrachoa differ primarily from plants of ‘USCALI51’ in the following characteristics:

• • 1. Plants of the new Calibrachoa are more outwardly spreading than and not as upright as plants of ‘USCALI51’.
  • 2. Plants of the new Calibrachoa and ‘USCALI51’ differ in flower color as flowers of plants of the new Calibrachoa are red purple in color with bright yellow-colored centers whereas flowers of plants of ‘USCALI11’ are violet in color.

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. At the top of the photographic sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘BBCAL91303’ grown in a container and at the bottom of the photographic sheet is a close-up view of a typical flowering plant of ‘BBCAL91303’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the spring in 15.25-cm containers in a polyethylene-covered greenhouse in St. Thomas, Ontario, Canada and under cultural practices typical of commercial Calibrachoa production. During the production of the plants, day temperatures averaged 27° C. and night temperatures averaged 15° C. Plants were pinched three weeks after planting and were ten weeks from planting rooted cuttings when the photographs and description were taken.
