Abstract

A distinct cultivar of Dahlia plant named ‘Melody Dixie’, characterized by its upright, somewhat outwardly spreading and uniform plant habit; freely branching habit; dark green foliage; freely flowering habit; decorative inflorescence form with inflorescences positioned above the foliage; light and dark purple-colored ray florets; and excellent garden performance.

Description

BACKGROUND OF THE INVENTION
The present Invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia hybrida and hereinafter referred to by the name ‘Melody Dixie’.
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 Dahlia cultivars with uniform growth habit, decorative inflorescence form, attractive ray floret colors, and good inflorescence longevity.
The new Dahlia originated from a cross pollination made by the Inventor in 1997 of the two unidentified Dahlia hybrida selections, not patented. 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 Lisse, The Netherlands, in 1997. The selection of this plant was based on its uniform plant habit and attractive ray floret coloration.
Asexual reproduction of the new Dahlia by cuttings was first conducted in Lisse, The Netherlands. 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 INVENTION
The cultivar Melody Dixie has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, light intensity, water and nutritional status without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Melody Dixie’. These characteristics in combination distinguish ‘Melody Dixie’ as a new and distinct Dahlia:
1. Upright, somewhat outwardly spreading and uniform plant habit.
2. Freely branching habit, full and dense plants.
3. Dark green foliage.
4. Freely flowering habit.
5. Decorative inflorescence form with inflorescences positioned above the foliage.
6. Light and dark purple bi-colored ray florets.
7. Excellent garden performance.
Plants of the new Dahlia differ primarily from plants of the parent selections in ray floret coloration.
Plants of the new Dahlia can be compared to plants of the Dahlia cultivar Oriental Dream, not patented. In side-by-side comparisons conducted by the Inventor in Lisse, The Netherlands, plants of the new Dahlia were more compact, had more ray florets per inflorescence, and had lighter purple-colored ray floret apices than plants of the cultivar Oriental Dream.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying colored photographs illustrate 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 photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia.
The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Melody Dixie’ that were about four months old.
The photograph on the second sheet comprises a close-up view of a typical inflorescence of ‘Melody Dixie’.
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. The afore-mentioned photographs 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 23° C. and night temperatures ranged between 10 and 15° C. Measurements and numerical values represent averages of typical flowering plants that were about four months old.
