Abstract
A distinct cultivar of Dahlia plant named ‘Rousillon’, characterized by its upright, uniformly mounded and compact plant habit; freely branching habit, full and dense plants; continuous and freely flowering during the spring until fall; full inflorescences with multiple rows of ray florets; dark orange-colored ray florets with bright yellow-colored disc florets; and excellent garden and patio container performance.
Description
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia variabilis, commercially referred to as a pot-type Dahlia, and hereinafter referred to by the cultivar name Rousillon.
The new Dahlia is a product of a planned breeding program conducted by the Inventor in Hillegom, The Netherlands. The objective of the breeding program is to create new pot-type Dahlia cultivars with desirable inflorescence form, attractive colors, and good garden performance.
The new Dahlia originated from a cross made by the Inventor in 1995 of two unidentified proprietary Dahlia variabilis seedling selections. The new Dahlia was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross grown in a controlled environment in Hillegom, The Netherlands. The selection of this plant was based on its desirable inflorescence form and attractive floret colors.
Asexual reproduction of the new Dahlia by vegetative tip cuttings was first conducted in Hillegom, The Netherlands in 1996. Asexual reproduction by cuttings has shown that the unique features of this new Dahlia are stable and reproduced true to type in successive generations.
The cultivar Rousillon has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Rousillon’. These characteristics in combination distinguish ‘Rousillon’ as a new and distinct pot-type Dahlia:
1. Upright, uniformly mounded and compact plant habit.
2. Freely branching, full and dense plants.
3. Continuous and freely flowering during the spring until fall.
4. Full inflorescences with multiple rows of ray florets.
5. Dark orange-colored ray florets with bright yellow-colored disc florets.
6. Excellent garden and patio container performance.
Plants of the new Dahlia differ from plants of the parent selections and Dahlia cultivars known to the Inventor primarily in ray floret coloration and its freely flowering habit.
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 more accurately describe the actual colors of the new Dahlia. The photograph comprises a side perspective view of a typical flowering plant of ‘Rousillon’.
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. The following observations and measurements describe plants grown and flowered during the spring and summer in Keller, Tex., under outdoor conditions which approximate those generally used in commercial production. One rooted cutting was planted in a 12.5-cm container and pinched twice. Measurements and numerical values represent averages of typical flowering plants about 10 weeks after planting.
