Description

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION
Calibrachoa sp. cultivar Illumination Rose 2.
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 ‘Illumination Rose 2’.
The new Calibrachoa is a product of a planned breeding program conducted by the Inventors in Tochigi, Japan. The objective of the breeding program is to create new early flowering Calibrachoa cultivars that have stronger growth and attractive flower coloration.
The new Calibrachoa originated from a cross-pollination made by the Inventors in August, 1997, in Tochigi, Japan, of an unnamed proprietary Calibrachoa selection, not patented, as the female, or seed, parent with an unnamed proprietary Calibrachoa selection, not patented, as the male, or pollen, parent. The new Calibrachoa was discovered and selected by the Inventors as a single flowering plant within the progeny of the stated cross-pollination grown in a controlled environment in Tochigi, Japan, in October, 1998. The selection of this plant was based on its strong plant growth habit and attractive flower coloration.
Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Saitama-ken, Japan, since January, 1999, 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 Illumination Rose 2 have not been observed under all possible environmental conditions. The phenotype may vary somewhat 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 ‘Illumination Rose 2’. These characteristics in combination distinguish ‘Illumination Rose 2’ as a new and distinct cultivar of Calibrachoa:
1. Cascading and prostrate plant habit.
2. Freely branching growth habit.
3. Early flowering habit.
4. Purple-colored flowers with yellow-colored throat.
5. Good weather tolerance; tolerant to wind, rain, and low and high temperatures.
Plants of the new Calibrachoa can be compared to plants of the female parent, an unnamed proprietary Calibrachoa selection. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the female parent primarily in growth habit as plants of the new Calibrachoa were more prostrate and not as upright as plants of the female parent. In addition plants of the new Calibrachoa and the female parent differed in petal color as plants of the female parent had dark pink-colored petals.
Plants of the new Calibrachoa can be compared to plants of the male parent, an unnamed proprietary Calibrachoa selection. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the male parent primarily in flowering time as plants of the new Calibrachoa flowered earlier than plants of the male parent.
Plants of the new cultivar can also be compared to plants of the cultivar Sunbelkupi, disclosed in U.S. Plant Pat. No. 10,287. In side-by-side comparisons conducted by the Inventors in Tochigi, Japan, plants of the new Calibrachoa differed from plants of the cultivar Sunbelkupi in the following characteristics:
1. Plants of the new Calibrachoa had lighter green-colored leaves than plants of the cultivar Sunbelkupi.
2. Plants of the new Calibrachoa had larger flowers than plants of the cultivar Sunbelkupi.
3. Plants of the new Calibrachoa and the cultivar Sunbelkupi differed in corolla coloration.
4. Plants of the new Calibrachoa had shorter peduncles than plants of the cultivar Sunbelkupi.
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 photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Calibrachoa.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Illumination Rose 2’.
The photograph on the second sheet comprises a close-up view of a typical flower of ‘Illumination Rose 2’.
DETAILED BOTANICAL DESCRIPTION
In the following description, color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. Twenty-centimeter containers with three plants per container were used for the aforementioned photographs and the following description. Plants were grown under conditions which closely approximate commercial production conditions during the winter in Santa Paula, Calif. in a polyethylene-covered greenhouse. Plants used for the photographs and the description were about 14 weeks from planting rooted young plants. During the production period, day temperatures averaged 28° C., night temperatures averaged 21° C., and light levels were about 5,000 footcandles.
