Botanical designation: Dianthus caryophyllus.
Cultivar denomination: ‘KOCOSMO’.
The present invention relates to a new and distinct cultivar of Carnation plant, botanically known as Dianthus caryophllus, grown as a potted plant, and hereinafter referred to by the name ‘Kocosmo’.
The new Carnation is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new freely-branching Carnation cultivars with numerous flowers and attractive flower coloration.
The new Carnation originated from a cross-pollination made by the Inventor during the summer of 2002, of a proprietary selection of Dianthus caryophyllus identified as code number 99-3-36, not patented, as the female, or seed, parent with Dianthus caryophyllus ‘Iglo’, not patented, as the male, or pollen, parent. The cultivar Kocosmo was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Aalsmeer, The Netherlands during the spring of 2003.
Asexual reproduction of the new cultivar by terminal cuttings propagated in a controlled greenhouse environment in Aalsmeer, The Netherlands since the spring of 2003, has shown that the unique features of this new Carnation are stable and reproduced true to type in successive generations of asexual reproduction.
The new Carnation has 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 ‘Kocosmo’. These characteristics in combination distinguish ‘Kocosmo’ as a new and distinct cultivar of Carnation:
Plants of the new Carnation differ from plants of the female parent selection and ‘Iglo’ in the following characteristics:
Plants of the new Carnation can be compared to plants of the Carnation ‘Cristal’, disclosed in U.S. Plant Pat. No. 17,945. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Carnation differed from plants of ‘Cristal’ in the following characteristics:
The accompanying photograph illustrates the overall appearance of the new Carnation. This photograph shows 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 Carnation. The photograph comprises a side perspective view of a typical flowering plant of ‘Kocosmo’ grown in a container.
In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. Measurements and numerical values represent averages for typical flowering plants. The aforementioned photograph and following observations and measurements describe plants grown in Aalsmeer, The Netherlands during the summer in a glass-covered greenhouse and under conditions and practices which approximate those generally used in commercial potted Carnation production. During the production of the plants, day temperatures averaged 20° C., night temperatures averaged 14° C. and light levels averaged 7,000 lux. Single plants were grown in 10-cm pots and were pinched one time. Plants were five months old when the photograph and the detailed description were taken.
