CROSS-REFERENCE TO RELATED APPLICATIONSDahlia Plant Named ‘HS Date’; Aad W. M. Verwer, Applicant; disclosed in U.S. Plant patent application Ser. No. 11/146,222. Dahlia Plant Named ‘HS Juliet’; Aad W. M. Verwer, Applicant; disclosed in U.S. Plant patent application Ser. No. 11/146,220.
BACKGROUND OF THE INVENTIONThe present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida and hereinafter referred to by the name ‘HS Kiss’.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Lisse, The Netherlands. The objective of the breeding program is to create new compact potted Dahlia cultivars that have a freely branching growth habit, dark green-colored foliage, early and freely flowering habit, daisy inflorescence form, attractive ray floret coloration, inflorescences that are not persistent, and good postproduction longevity and garden performance.
The new Dahlia originated from a chance open-pollination in 1999 of a proprietary selection of Dahlia hybrida identified as code number V00-c1-dr, not patented, as the female, or seed, parent with an unknown selection of Dahlia hybrida as the male, or pollen, parent. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated open-pollination grown in a controlled environment in Lisse, The Netherlands in 2000.
Asexual reproduction of the new Dahlia by cuttings was first conducted in Lisse, The Netherlands during the spring of 2001. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTIONThe cultivar HS Kiss 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 ‘HS Kiss’. These characteristics in combination distinguish ‘HS Kiss’ as a new and distinct Dahlia cultivar:
-
- 1. Upright and outwardly spreading plant habit.
- 2. Freely branching growth habit.
- 3. Dark-colored foliage.
- 4. Early and freely flowering habit.
- 5. Daisy inflorescence form.
- 6. Large inflorescences with salmon orange and red bi-colored ray florets.
- 7. Good postproduction longevity and garden performance.
Plants of the new Dahlia differ primarily from plants of the female parent selection in the following characteristics:
-
- 1. Plants of the new Dahlia are much more compact than plants of the female parent selection.
- 2. Plants of the new Dahlia and the female parent selection differ in inflorescence form.
- 3. Plants of the new Dahlia and the female parent selection differ in ray floret coloration.
Plants of the new Dahlia can be compared to the Dahlia cultivars HS Date, disclosed in U.S. Plant patent application Ser. No. 11/146,222, and HS Juliet, disclosed in U.S. Plant patent application Ser. No. 11/146,220. Plants of the new Dahlia differ from plants of the cultivars HS Date and HS Juliet primarily in ray floret coloration.
Plants of the new Dahlia can also be compared to plants of the cultivar Sunshine, not patented. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Sunshine in the following characteristics:
-
- 1. Plants of the new Dahlia were broader than plants of the cultivar Sunshine.
- 2. Plants of the new Dahlia were more freely flowering than plants of the cultivar Sunshine.
- 3. Plants of the new Dahlia had smaller inflorescences than plants of the cultivar Sunshine.
- 4. Ray florets of plants of the new Dahlia were salmon orange and red bi-colored whereas ray florets of plants of the cultivar Sunshine were yellow orange in color.
- 5. Plants of the new Dahlia had more and larger disc florets per inflorescence than plants of the cultivar Sunshine.
The accompanying colored photograph illustrates the overall appearance of the new Dahlia showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia. The photograph comprises a side perspective view of a typical flowering plant of ‘HS Kiss’.
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. The aforementioned photograph and the following observations and measurements describe plants grown and flowered during the summer and early autumn in Lisse, The Netherlands, in an outdoor nursery and under conditions which approximate those generally used in commercial production. During the production of the plants, day temperatures ranged between 15 and 30° C. and night temperatures ranged between 10 and 20° C. Plants were pinched one time about three to four weeks after planting rooted cuttings. Plants were about four months old when the photographs and the description were taken.
