Abstract

A new and distinct cultivar of Calibrachoa plant named ‘USCAL85101’, characterized by its upright, outwardly spreading to trailing and low mounding plant habit; freely branching growth habit; dense and bushy appearance; early and freely flowering habit; white-colored flowers with large yellow-colored centers and throats; and good garden performance.

Description

Botanical designation: Calibrachoa sp.

Cultivar denomination: ‘USCAL85101’.

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 ‘USCAL85101’.

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 8, 2008 in Higashiomi, Shiga, Japan of a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-80, not patented, as the female, or seed, parent with a proprietary seedling selection of Calibrachoa sp. identified as code name CJ08-32, 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 ‘USCAL85101’. These characteristics in combination distinguish ‘USCAL85101’ as a new and distinct Calibrachoa plant:

- 1. Upright, outwardly spreading to trailing and low mounding plant habit.
- 2. Freely branching growth habit; dense and bushy appearance.
- 3. Early and freely flowering habit.
- 4. White-colored flowers with large yellow-colored centers and throats.
- 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 upright than 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 white-colored flowers with red-colored venation.

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 the following characteristics:

- 1. Plants of the new Calibrachoa are more upright than plants of the male parent selection.
- 2. Plants of the new Calibrachoa and the male parent selection differ in flower color as plants of the male parent selection have pink-colored flowers with yellow-colored centers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘USCALI386-2’, disclosed in U.S. Plant Pat. No. 19,734. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘USCALI386-2’ in the following characteristics:

- 1. Plants of the new Calibrachoa were more upright than plants of ‘USCALI386-2’.
- 2. Plants of the new Calibrachoa and ‘USCALI386-2’ differed in flower color as plants of ‘USCALI386-2’ had solid white-colored flowers.

Plants of the new Calibrachoa can be compared to plants of the Calibrachoa ‘KLECA07137’, not patented. In side-by-side comparisons conducted in Bonsall, Calif., plants of the new Calibrachoa differed primarily from plants of ‘KLECA07137’ in flower color as plants of ‘KLECA07137’ had white-colored flowers with pale yellow-colored throats.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Calibrachoa plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘USCAL85101’ grown in a container.

The photograph at the top of the sheet is a close-up view of typical flowers of ‘USCAL85101’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring in 11.4-cm containers in a polyethylene-covered greenhouse and finished in an outdoor nursery in Bonsall, Calif. During the production of the plants, day temperatures averaged 24° C. and night temperatures averaged 18° C. Plants were pinched one time and were seven weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
