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 Latin’.

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 Dahlia cultivars with freely branching 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 1996 of the Dahlia hybrida Gallery Art Deco, disclosed in U.S. Plant Pat. No. 10,525, as the female or seed parent with the Dahlia hybrida cultivar München, 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 grown in a controlled environment in Lisse, The Netherlands, in the summer of 1997. The selection of this plant was based on its compact plant habit and attractive ray floret coloration.

Asexual reproduction of the new Dahlia by cuttings was first conducted in Lisse, The Netherlands in the spring of 1998. 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 Latin 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 Latin’. These characteristics in combination distinguish ‘Melody Latin’ as a new and distinct Dahlia:

1. Upright, somewhat outwardly spreading and rounded plant habit.

2. Freely branching habit, full and dense plants.

3. Freely flowering habit.

4. Decorative inflorescence form with inflorescences positioned just above the foliage.

5. Yellow-colored ray florets that do not fade with subsequent development.

6. Excellent garden performance.

7. Excellent inflorescence longevity.

Plants of the new Dahlia are taller than plants of the female parent, the cultivar Gallery Art Deco. In addition, plants of the new Dahlia have yellow-colored ray florets whereas plants of the cultivar Gallery Art Deco have bronze-colored ray florets.

Plants of the new Dahlia are taller, have smaller inflorescences and more ray florets per inflorescence than plants of the male parent, the cultivar München. In addition, cuttings of plants of the new Dahlia root easily whereas cuttings of plants of the cultivar München do not root easily.

Plants of the new Dahlia can be compared to plants of the cultivar Gallery Cezanne, disclosed in U.S. Plant Pat. No. 10,511. In side-by-side comparisons conducted in Lisse, The Netherlands, plants of the new Dahlia are taller, have longer internodes and larger inflorescences than plants of the cultivar Gallery Cezanne. In addition, inflorescences of plants of the new Dahlia maintain their yellow coloration with age whereas inflorescences of plants of the cultivar Gallery Cezanne turn brownish with age.

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 following observations and measurements describe plants grown and flowered during the summer and early autumn of 2000 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. Plants were pinched one time about three to four weeks after planting. Measurements and numerical values represent average of typical flowering plants that were about four months old.
