A new and distinct cultivar of Calibrachoa plant named ‘USCAL58205’, characterized by its compact, mounding and outwardly spreading plant habit; vigorous and freely branching growth habit; dense and bushy appearance; early and freely flowering habit; pink-colored flowers with greyed purple-colored centers; and good 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 ‘USCAL58205’.

The newCalibrachoaplant 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 newCalibrachoaplants with uniform plant habit, freely branching growth habit, attractive flowers and good garden performance.

The newCalibrachoaplant originated from a cross-pollination made by the Inventor on May 8, 2006 in Higashiomi, Shiga, Japan of a proprietary seedling selection ofCalibrachoasp. identified as code number CJ06, not patented, as the female, or seed, parent with a proprietary seedling selection ofCalibrachoasp. identified as code number C459-04, not patented, as the male, or pollen, parent. The newCalibrachoaplant 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 Jul. 17, 2007.

Asexual reproduction of the newCalibrachoaplant by terminal cuttings in a controlled environment in Bonsall, Calif. since Jul. 20, 2007 has shown that the unique features of this newCalibrachoaplant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the newCalibrachoahave not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘USCAL58205’. These characteristics in combination distinguish ‘USCAL58205’ as a new and distinct cultivar ofCalibrachoa:1. Compact, mounding and outwardly spreading plant habit.2. Vigorous and freely branching growth habit; dense and bushy appearance.3. Early and freely flowering habit.4. Pink-colored flowers with greyed purple-colored centers.5. Good garden performance.

The newCalibrachoaplant can be compared to plants of the parent selections. Plants of the newCalibrachoadiffer primarily from plants of the parent selections in flower color as plants of the female parent selection have dark pink-colored flowers with large darker pink-colored centers and plants of the male parent selection have pink-colored flowers with red-colored centers.

Plants of the newCalibrachoacan be compared to plants of theCalibrachoa‘USCALI17’, disclosed in U.S. Plant Pat. No. 15,701. In side-by-side comparisons conducted in Bonsall, Calif., plants of the newCalibrachoadiffered primarily from plants of ‘USCALI17’ in the following characteristics:1. Plants of the newCalibrachoawere more compact than plants of ‘USCALI17’.2. Leaves of plants of the newCalibrachoawere darker green in color than leaves of plants of ‘USCALI17’.3. Plants of the newCalibrachoaand ‘USCALI17’ differed in flower color as plants of ‘USCALI17’ had red purple-colored flowers.

Plants of the newCalibrachoacan also be compared to plants of the Petunia ‘Sunbelochipi’, disclosed in U.S. Plant Pat. No. 10,355. In side-by-side comparisons conducted in Bonsall, Calif., plants of the newCalibrachoadiffered from plants of ‘Sunbelochipi’ in the following characteristics:1. Plants of the newCalibrachoawere more compact than and not as vigorous as plants of ‘Sunbelochipi’.2. Plants of the newCalibrachoaand ‘Sunbelochipi’ differed in flower color as plants of ‘Sunbelochipi’ had red purple-colored flowers.
