Abstract: A new and distinct cultivar of Calibrachoa plant named `Wescarasp`, characterized by its semi-upright and vigorous growth habit; freely branching habit; short internodes; dense and bushy appearance; relatively small-sized leaves; medium-sized flowers; and numerous red purple-colored flowers with dark purple-colored venation and circumorbital ring.
Claim: It is claimed:

1. A new and distinct cultivar of Calibrachoa plant named `Wescarasp`, as illustrated and described.
Description: Botanicaldesignation: Calibrachoa sp.

Cultivar denomination: `Wescarasp`.

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 `Wescarasp`.

The new Calibrachoa is a product of a planned breeding program conducted by the Inventor in Sudlohn, 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 2000 of a proprietary selection of Calibrachoa identified as code number 00P108, not patented, as the female, or seed, parent with a proprietary selection ofCalibrachoa identified as code number 00P192, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventor in a controlled environment in Sudlohn, Germany as a single plant within the resulting progenyfrom the cross-pollination.

Asexual reproduction of the new cultivar by terminal cuttings at Sudlohn, Germany since 2001, 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 Wescarasp 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 `Wescarasp`. These characteristics in combination distinguish `Wescarasp` as a new and distinct cultivar of Calibrachoa: 1. Semi-uprightand vigorous growth habit. 2. Freely branching habit; short internodes; dense and bushy appearance. 3. Relatively small-sized leaves. 4. Medium-sized flowers. 5. Numerous red purple-colored flowers with dark purple-colored venation andcircumorbital ring.

Plants of the cultivar Wescarasp can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed from plants of the female parent selection in thefollowing characteristics: 1. Plants of the new Calibrachoa had darker green-colored leaves 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 femaleparent selection had lighter pink-colored flowers.

Plants of the cultivar Wescarasp can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed from plants of the male parent selection in the followingcharacteristics: 1. Plants of the new Calibrachoa were more upright than and not as cascading as plants of the male parent selection. 2. Plants of the new Calibrachoa had shorter internodes than plants of the male parent selection. 3. Plants of thenew Calibrachoa and the male parent selection differed in flower color as plants of the male parent selection had blue violet-colored flowers.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Wescadarkblue, disclosed in U.S. Plant Pat. No. 15,119. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differedfrom plants of the cultivar Wescadarkblue in the following characteristics: 1. Plants of the new Calibrachoa were more compact and more upright than plants of the cultivar Wescadarkblue. 2. Plants of the new Calibrachoa had broader leaves than plantsof the cultivar Wescadarkblue. 3. Plants of the new Calibrachoa had shorter peduncles than plants of the cultivar Wescadarkblue. 4. Plants of the new Calibrachoa and the cultivar Wescadarkblue differed in flower color.

Plants of the new Calibrachoa can also be compared to plants of the Calibrachoa cultivar Wescaplum, disclosed in U.S. Plant Pat. No. 15,069. In side-by-side comparisons conducted in Sudlohn, Germany, plants of the new Calibrachoa differed fromplants of the cultivar Wescaplum in the following characteristics: 1. Plants of the new Calibrachoa were more upright than and not as cascading as plants of the cultivar Wescaplum. 2. Plants of the new Calibrachoa had smaller and darker green-coloredleaves than plants of the cultivar Wescaplum. 3. Plants of the new Calibrachoa had lighter purple-colored flowers than plants of the cultivar Wescaplum.

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 slightlyfrom the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.

The photograph at the bottom of the sheet comprises a side perspective view of typical flowering plants of `Wescarasp` grown in a container.

The photograph at the top of the sheet is a close-up view of typical flowers of `Wescarasp`.

DETAILED BOTANICAL DESCRIPTION

Plants used in the aforementioned photographs and for the following description were grown under conditions which closely approximate commercial production conditions during the spring and summer in a glass-covered greenhouse in Sudlohn, Germany. Plants were about 20 weeks from planting rooted cuttings and grown in containers. During the production of the plants, the day temperatures ranged from 20 to 25.degree. C., night temperatures ranged from 16 to 18.degree. C. and light levels rangedfrom 3,000 to 50,000 lux.
