Dahlia plant named ‘Melody Harmony’

Abstract

A new and distinct cultivar of Dahlia plant named ‘Melody Harmony’, characterized by its upright, somewhat outwardly spreading and mounded plant habit; freely branching growth habit; dark-colored foliage; freely flowering habit; decorative-type inflorescence form; large inflorescences with light purple-colored ray florets; and good postproduction longevity and garden performance.

Description

Botanical designation: Dahlia hybrida.

Cultivar denomination: ‘Melody Harmony’.

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 Harmony’.

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 container-type Dahlia cultivars that have a freely branching growth habit, early and freely flowering habit, daisy inflorescence form, attractive ray floret coloration, and good postproduction longevity and garden performance.

The new Dahlia originated from a cross-pollination in Lisse, The Netherlands in 2000, of a proprietary selection of Dahlia hybrida identified as code number VP 61, not patented, as the female, or seed, parent with the Dahlia hybrida cultivar Silver Years, not patented, 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 cross-pollination in a controlled environment in Lisse, The Netherlands during the summer of 2001.

Asexual reproduction of the new Dahlia by cuttings since the spring of 2002 in a controlled environment in Lisse, The Netherlands, 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 Harmony 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 ‘Melody Harmony’. These characteristics in combination distinguish ‘Melody Harmony’ as a new and distinct cultivar of Dahlia:

• • 1. Upright, somewhat outwardly spreading and mounded plant habit.
  • 2. Freely branching growth habit.
  • 3. Dark-colored foliage.
  • 4. Freely flowering habit.
  • 5. Decorative-type inflorescence form.
  • 6. Large inflorescences with light purple-colored ray florets.
  • 7. Good postproduction longevity and garden performance.

Compared to plants of the parents, the female selection and the cultivar Silver Years, plants of the new Dahlia differ primarily in leaf coloration, ray floret coloration and plant size.

Plants of the new Dahlia can be compared to plants of the Dahlia cultivar Melody Dixie, disclosed in U.S. Plant Pat. No. 12,911. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia differed from plants of the cultivar Melody Dixie in the following characteristics:

• • 1. Plants of the new Dahlia were larger than plants of the cultivar Melody Dixie.
  • 2. Plants of the new Dahlia were more freely branching and bushier than plants of the cultivar Melody Dixie.
  • 3. Plants of the new Dahlia and the cultivar Melody Dixie differed in leaf coloration.
  • 4. Plants of the new Dahlia had larger inflorescences than plants of the cultivar Melody Dixie.
  • 5. Ray florets of plants of the new Dahlia were light purple in color whereas ray florets of plants of the cultivar Melody Dixie were dark purple in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Dahlia. The 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 Dahlia. The photograph comprises a side perspective view of a typical flowering plant of ‘Melody Harmony’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

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 following observations and measurements describe plants grown in Lisse, The Netherlands during the summer in an outdoor nursery and under conditions and practices which approximate those generally used in commercial Dahlia production. During the production of the plants, day temperatures ranged from 15° C. to 30° C. and night temperatures ranged from 10° C. to 20° C. Plants were pinched one time about three to four weeks after planting. Measurements and numerical values represent averages for typical flowering plants. Plants were about four months old when the photograph and description were taken.
