Abstract

A new and distinct cultivar of Calibrachoa plant named ‘Wescaosu’, characterized by its upright to cascading and vigorous growth habit; short internodes and freely branching habit; dense and bushy appearance; medium-sized leaves; medium-sized flowers; and numerous orange and red bi-colored flowers.

Description

Botanical designation: Calibrachoa sp.
Cultivar denomination: ‘Wescaosu’.
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 cultivar name ‘Wescaosu’.
The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Südlohn, Germany. The objective of the breeding program is to develop new vigorous Calibrachoa cultivars with attractive and unique flower coloration.
The new Calibrachoa originated from a cross-pollination made by the Inventor in 2003 of a proprietary selection of Calibrachoa identified as code number 03P915, not patented, as the female, or seed, parent with a proprietary selection of Calibrachoa identified as code number 03P816, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor in a controlled environment in Südlohn, Germany as a single plant within the resulting progeny from the stated cross-pollination.
Asexual reproduction of the new cultivar by terminal cuttings at Südlohn, Germany since 2004, has shown that the unique features of this new Calibrachoa are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the cultivar Wescaosu have not been observed under all possible environmental conditions. The phenotype may vary with variations in environment 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 ‘Wescaosu’. These characteristics in combination distinguish ‘Wescaosu’ as a new and distinct cultivar of Calibrachoa:
    • 1. Upright to cascading and vigorous growth habit.
    • 2. Short internodes and freely branching habit; dense and bushy appearance.
    • 3. Medium-sized leaves.
    • 4. Medium-sized flowers.
    • 5. Numerous orange and red bi-colored flowers.
Plants of the cultivar Wescaosu can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the female parent selection in the following characteristics:
    • 1. Plants of the new Calibrachoa were more compact than plants of the female parent selection.
    • 2. Plants of the new Calibrachoa and the female parent selection differed in flower color as plants of the female parent selection had yellow-colored flowers with red-colored venation.
Plants of the cultivar Wescaosu can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the male parent selection in the following characteristics:
    • 1. Plants of the new Calibrachoa had smaller leaves than plants of the male parent selection.
    • 2. Plants of the new Calibrachoa had smaller flowers than plants of the male parent selection.
    • 3. Plants of the new Calibrachoa and the male parent selection differed in flower color as plants of the male parent selection had red-colored flowers.
Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Wescaora, disclosed in U.S. Plant Pat. No. 14,822. In side-by-side comparisons conducted in Südlohn, Germany, plants of the new Calibrachoa differed from plants of the cultivar Wescaora in the following characteristics:
    • 1. Plants of the new Calibrachoa were more mounding than plants of the cultivar Wescaora.
    • 2. Plants of the new Calibrachoa had smaller leaves than plants of the cultivar Wescaora.
    • 3. Plants of the new Calibrachoa and the cultivar Wescaora differed in flower color as plants of the cultivar Wescaora had yellow orange-colored flowers.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate the overall appearance of the new cultivar, 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.
The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Wescaosu’ grown in a container.
The photograph at the bottom of the sheet is a close-up view of a typical flower of ‘Wescaosu’.
