Botanical designation: Nemesia hybrida.
Cultivar denomination: ‘KLENH05138’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Nemesia, botanically known as Nemesia hybrida and hereinafter referred to by the name ‘KLENH05138’.
The new Nemesia is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program is to create new compact Nemesia cultivars with good vigor and attractive flower coloration.
The new Nemesia originated from an open-pollination in June, 2002 in Stuttgart, Germany of a proprietary selection of Nemesia hybrida identified as code number V 032, not patented, as the female, or seed, parent with an unknown selection of Nemesia hybrida as the male, or pollen, parent. The new Nemesia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Stuttgart, Germany in June, 2003.
Asexual reproduction of the new Nemesia by terminal cuttings in a controlled environment in Stuttgart, Germany since September, 2003, has shown that the unique features of this new Nemesia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The cultivar KLENH05138 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature, daylength 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 ‘KLENH05138’. These characteristics in combination distinguish ‘KLENH05138’ as a new and distinct cultivar of Nemesia:
- 1. Upright, outwardly spreading and compact growth habit.
- 2. Freely branching and flowering plant habit.
- 3. Violet blue-colored flowers.
Plants of the new Nemesia differ from plants of the female parent selection in the following characteristics:
- 1. Plants of the new Nemesia are larger than plants of the female parent selection.
- 2. Plants of the new Nemesia have larger flowers than plants of the female parent selection.
Plants of the new Nemesia can be compared to plants of the cultivar KLENE04146, disclosed in U.S. Plant patent application Ser. No. 11/343,865. In side-by-side comparisons conducted by the Inventor in Stuttgart, Germany, plants of the new Nemesia differed from plants of the cultivar KLENE04146 in the following characteristics:
- 1. Plants of the new Nemesia were larger than plants of the cultivar KLENE04146.
- 2. Plants of the new Nemesia and the cultivar KLENE04146 differed in flower color.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying colored photograph illustrates the overall appearance of the new Nemesia, 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 Nemesia. The photograph comprises a close-up view of a typical flowering plant of ‘KLENH05138’ grown in a container.
DETAILED BOTANICAL DESCRIPTION
The photograph and following observations, measurements and values describe plants grown in Stuttgart, Germany in containers in a glass-covered greenhouse during the spring and under conditions which closely approximate commercial production. During the production of the plants, day temperatures ranged from 18° C. to 22° C., night temperatures ranged from 12° C. to 18° C. and maximum light levels were 60,000 lux. Plants were pinched one time and were about eleven weeks old when the photograph and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
