A new and distinct Calibrachoa plant named ‘WNCALSBDBLRS24’, characterized by its compact, upright to outwardly spreading and mounding to trailing plant habit; moderately vigorous growth habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; double-type flowers with deep red-colored petals and petaloids with bright yellow-colored picotee edges; and excellent container and garden performance.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofCalibrachoaplant, botanically known asCalibrachoasp. and hereinafter referred to by the name ‘WNCALSBDBLRS24’.

The newCalibrachoaplant 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-floweringCalibrachoaplants with attractive double-type flowers and good container and garden performance.

The newCalibrachoaplant originated from a cross-pollination conducted by the Inventor in Bonsall, California on Sep. 26, 2018 of a proprietary seedling selection ofCalibrachoasp. identified as code number 16CB849-05, not patented, as the female, or seed, parent with a proprietary seedling selection ofCalibrachoasp. identified as code number 16CU751-02, not patented, as the male, or pollen, parent. The newCalibrachoaplant 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 Aug. 26, 2019.

Asexual reproduction of the newCalibrachoaplant by vegetative terminal cuttings in a controlled greenhouse environment in Bonsall, California since Aug. 26, 2019 has shown that the unique features of this newCalibrachoaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘WNCALSBDBLRS24’.These characteristics in combination distinguish ‘WNCALSBDBLRS24’ as a new and distinctCalibrachoaplant: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. Double-type flowers with deep red-colored petals and petaloids with bright yellow-colored picotee edges.6. Excellent container and garden performance.

Plants of the newCalibrachoadiffer primarily from plants of the female parent selection in the following characteristics:1. Plants of the newCalibrachoaare more upright than and not as spreading as plants of the female parent selection.2. Plants of the newCalibrachoahave double-type flowers whereas plants of the female parent selection have single-type flowers.3. Flower petals and petaloids of plants of the newCalibrachoaare deep red in color with bright yellow-colored picotee edges whereas flower petals of plants of the female parent selection are solid salmon red in color.

Plants of the newCalibrachoadiffer primarily from plants of the male parent selection in the following characteristics:1. Plants of the newCalibrachoaare more upright than and not as trailing as plants of the male parent selection.2. Plants of the newCalibrachoahave double-type flowers whereas plants of the male parent selection have single and double-type flowers.3. Flower petals and petaloids of plants of the newCalibrachoaare deep red in color with bright yellow-colored picotee edges whereas flower petals and petaloids of plants of the male parent selection are dark cherry red and yellow in color and flowers have black-colored centers.

Plants of the newCalibrachoacan be compared to plants of theCalibrachoasp. ‘USCAL51505’, disclosed in U.S. Plant Pat. No. 30,803. In side-by-side comparisons, plants of the newCalibrachoadiffer primarily from plants of ‘USCAL51505’ in the following characteristics:1. Plants of the newCalibrachoaare more upright than and not as spreading and trailing as plants of ‘USCAL51505’.2. Plants of the newCalibrachoaare not as vigorous as plants of ‘USCAL51505’.3. Flower petals and petaloids of plants of the newCalibrachoaare deep red in color with bright yellow-colored picotee edges whereas flower petals and petaloids of plants of ‘USCAL51505’ are pale yellow in color.

Plants of the newCalibrachoacan also be compared to plants of theCalibrachoasp. ‘USCAL81302’, disclosed in U.S. Plant Pat. No. 30,804. In side-by-side comparisons, plants of the newCalibrachoadiffer primarily from plants of ‘USCAL81302’ in the following characteristics:1. Plants of the newCalibrachoaare more upright than and not as trailing as plants of ‘USCAL81302’.2. Plants of the newCalibrachoaare more vigorous than plants of ‘USCAL81302’.3. Flower petals and petaloids of plants of the newCalibrachoaare deep red in color with bright yellow-colored picotee edges whereas flower petals and petaloids of plants of ‘USCAL81302’ are dark red purple in color with white-colored picotee edges.
