Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL91001’.

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 ‘USCAL91001’.

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 Calibrachoa plants with uniform plant habit, freely branching growth habit, unique flower coloration and good garden performance.

The new Calibrachoa plant originated from a cross-pollination made by the Inventor on May 11, 2008 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-61, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-38, 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 27, 2009.

Asexual reproduction of the new Calibrachoa plant by terminal cuttings in a controlled environment in Bonsall, Calif. since May 28, 2009 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 ‘USCAL91001’. These characteristics in combination distinguish ‘USCAL91001’ as a new and distinct Calibrachoa plant:

• • 1. Compact, upright to outwardly spreading and mounding plant habit.
  • 2. Freely branching growth habit; dense and bushy appearance.
  • 3. Early and freely flowering habit.
  • 4. Red purple-colored flowers with yellow-colored star-shaped pattern and centers.
  • 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 flower color as plants of the female parent selection have cherry pink-colored flowers with red-colored star-shaped pattern.

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 primarily in flower color as plants of the male parent selection have yellow-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘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 were more mounding than plants of ‘USCALI17’.
  • 2. Plants of the new Calibrachoa and ‘USCALI17’ differed in flower color as plants of ‘USCALI17’ had red purple-colored flowers without a star-shaped pattern.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘USCALI28’, disclosed in U.S. Plant Pat. No. 14,847. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCALI28’ in the following characteristics:

• • 1. Plants of the new Calibrachoa were more mounding than plants of ‘USCALI28’.
  • 2. Plants of the new Calibrachoa and ‘USCALI28’ differed in flower color as plants of ‘USCALI28’ had ruby red-colored flowers without a star-shaped pattern.
