Abstract

A new and distinct cultivar of Dahlia plant named ‘Fidahhypdanight’, characterized by its upright, somewhat outwardly spreading and mounded plant habit; early and freely flowering habit; large inflorescences with dark purple-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Dahlia variabilis.
Cultivar denomination: ‘FIDAHHYPDANIGHT’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Dahlia plant, botanically known as Dahlia variabilis, and hereinafter referred to by the name ‘Fidahhypdanight’.
The new Dahlia plant 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 that have a freely branching and flowering habit, attractive ray floret coloration and good postproduction longevity.
The new Dahlia plant originated from an open-pollination in Hillegom, The Netherlands of an unnamed selection of Dahlia variabilis, not patented, as the female, or seed, parent with an unknown selection of Dahlia variabilis as the male, or pollen, parent. The new Dahlia was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated open-pollination in a controlled environment in Hillegom, The Netherlands.
Asexual reproduction of the new Dahlia plant by cuttings in a controlled environment in Hillegom, The Netherlands since 2007, has shown that the unique features of this new Dahlia plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Dahlia have 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 ‘Fidahhypdanight’. These characteristics in combination distinguish ‘Fidahhypdanight’ as a new and distinct cultivar of Dahlia plant:
    • 1. Upright, somewhat outwardly spreading and mounded plant habit.
    • 2. Early and freely flowering habit.
    • 3. Large inflorescences with dark purple-colored ray florets.
    • 4. Good postproduction longevity.
Compared to plants of the female parent selection, plants of the new Dahlia differ primarily in ray floret coloration and plant shape.
Plants of the new Dahlia can be compared to plants of Dahlia ‘Fidahhypor’, not patented. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Dahlia differed from plants of ‘Fidahhypor’ in the following characteristics:
    • 1. Plants of the new Dahlia were not as freely branching as plants of ‘Fidahhypor’.
    • 2. Plants of the new Dahlia had longer peduncles than plants of ‘Fidahhypor’.
    • 3. Plants of the new Dahlia and ‘Fidahhypor’ differed in ray floret color as plants of ‘Fidahhypor’ had orange-colored ray florets.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Dahlia plant. The photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Dahlia plant.
The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Fidahhypdanight’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Fidahhypdanight’.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and the following observations and measurements describe plants grown during the winter in 15-cm containers in a glass-covered greenhouse in De Lier, The Netherlands under conditions and practices which approximate those generally used in commercial Dahlia production. During the production of the plants, day and night temperatures averaged 18° C. Plants were eight weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Fifth Edition, except where general terms of ordinary dictionary significance are used.
