plant named ‘USCAL23101’

Abstract

A new and distinct cultivar of Calibrachoa plant named ‘USCAL23101’, characterized by its compact, upright to outwardly spreading and mounding plant habit; freely branching habit; dense and bushy appearance; freely flowering habit; intense cherry red-colored flowers; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL23101’.

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 ‘USCAL23101’.

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

The new Calibrachoa plant originated from a cross-pollination made by the Inventor on May 5, 2010 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code number 10CJ49-01, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code number 09C896-12B, not patented, as the male, or pollen, parent. The new Calibrachoa plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Bonsall, Calif. on May 13, 2011.

Asexual reproduction of the new Calibrachoa plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 16, 2011 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 environmental conditions and various 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 ‘USCAL23101’. These characteristics in combination distinguish ‘USCAL23101’ as a new and distinct Calibrachoa plant:

• • 1. Compact, upright to outwardly spreading and mounding plant habit.
  • 2. Freely branching habit; dense and bushy appearance.
  • 3. Freely flowering habit.
  • 4. Intense cherry red-colored flowers.
  • 5. Good garden performance.

The new Calibrachoa plant can be compared to plants of the female parent selection. 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 mounding than and not as upright as plants of the female parent selection.
  • 2. Plants of the new Calibrachoa and the female parent selection differ in flower color as plants of the female parent selection have dark pink-colored flowers.

The new Calibrachoa plant can be compared to plants of the male parent selection. Plants of the new Calibrachoa differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have-reddish-pink-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa sp. ‘USCALI17’, disclosed in U.S. Plant Pat. No. 15,701. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCALI17’ in the following characteristics:

• • 1. Plants of the new Calibrachoa had darker green-colored leaves than plants of ‘USCALI17’.
  • 2. Plants of the new Calibrachoa flowered earlier than plants of ‘USCALI17’.
  • 3. Plants of the new Calibrachoa had larger flowers than plants of ‘USCALI17’.
  • 4. Plants of the new Calibrachoa and ‘USCALI17’ differed in flower color.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa sp. ‘Superbells Trailing Rose’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘Superbells Trailing Rose’ in the following characteristics:

• • 1. Plants of the new Calibrachoa were more mounding than and not as trailing as plants of ‘Superbells Trailing Rose’.
  • 2. Plants of the new Calibrachoa and ‘Superbells Trailing Rose’ differed in flower color.
