Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘WNCALSBPK24’.

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 ‘WNCALSBPK24’.

The new Calibrachoa plant is a product of a planned breeding program conducted by the Inventor in Bonsall, California. The objective of the breeding program is to create new compact, uniform, freely-branching and freely-flowering Calibrachoa plants with unique and attractive flowers and good container and garden performance.

The new Calibrachoa plant originated from a cross-pollination conducted by the Inventor in Bonsall, California on Sep. 25, 2019 of a proprietary seedling selection of Calibrachoa sp. identified as code number 18CB273-01, not patented, as the female, or seed, parent with Calibrachoa sp. ‘Duecalhulblu’, disclosed in U.S. Plant Pat. No. 30,202, 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, California on Jun. 1, 2020.

Asexual reproduction of the new Calibrachoa plant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, California since Jun. 3, 2020 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 ‘WNCALSBPK24’. These characteristics in combination distinguish ‘WNCALSBPK24’ as a new and distinct Calibrachoa plant:

• • 1. Compact, upright to outwardly spreading and mounding to trailing plant habit.
  • 2. Moderately vigorous growth habit.
  • 3. Freely branching habit; dense and bushy appearance.
  • 4. Early and freely flowering habit.
  • 5. Relatively large reddish purple-colored flowers with deeper purplish red-colored centers and yellow-colored throats.
  • 6. Excellent container and 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 trailing than and not as spreading as plants of the female parent selection.
  • 2. Plants of the new Calibrachoa are smaller than and not as vigorous as plants of the female parent selection.
  • 3. Flowers of plants of the new Calibrachoa are lighter in color than flowers of plants of the female parent selection.

Plants of the new Calibrachoa differ primarily from plants of the male parent, ‘Duecalhulblu’, in flower color as flowers of plants of the new Calibrachoa are reddish purple in color with deeper purplish red-colored centers and yellow-colored throats whereas flowers of plants of ‘Duecalhulblu’ are light and dark purple in color with light yellow-colored throats.

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 compact and denser than and not as open as plants of ‘USCALI11’.
  • 2. Plants of the new Calibrachoa are not as vigorous as plants of ‘USCALI11’.
  • 3. Plants of the new Calibrachoa flower earlier than plants of ‘USCALI11’.
  • 4. Flowers of plants of the new Calibrachoa are flatter and more open than flowers of plants of ‘USCALI11’.
  • 5. Flowers of plants of the new Calibrachoa are slightly lighter in color than flowers of plants of ‘USCALI11’.
