Abstract

A new and distinct cultivar of Dahlia plant named ‘Dodahhypelpin’, characterized by its relatively compact, broadly upright and uniformly mounding plant habit; relatively small dark green-colored leaves; early and freely flowering habit; large inflorescences with red purple-colored ray florets; and good postproduction longevity.

Description

Botanical designation: Dahlia variabilis.
Cultivar denomination: ‘DODAHHYPELPIN’.
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 ‘Dodahhypelpin’.
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 container Dahlia plants that have a freely branching and flowering habit, dark-colored leaves, large attractive inflorescences and good postproduction longevity.
The new Dahlia plant originated from a cross-pollination in Hillegom, The Netherlands of two unidentified proprietary selections of Dahlia variabilis, not patented. The new Dahlia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Hillegom, The Netherlands during the spring of 2014.
Asexual reproduction of the new Dahlia plant by vegetative terminal cuttings in a controlled greenhouse environment in De Lier, The Netherlands since the spring of 2014 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 combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions 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 ‘Dodahhypelpin’. These characteristics in combination distinguish ‘Dodahhypelpin’ as a new and distinct Dahlia plant:
    • 1. Relatively compact, broadly upright and uniformly mounding plant habit.
    • 2. Relatively small dark green-colored leaves.
    • 3. Early and freely flowering habit.
    • 4. Large inflorescences with red purple-colored ray florets.
    • 5. Good postproduction longevity.
Compared to plants of the parent selections, plants of the new Dahlia differ primarily in growth habit as plants of the new Dahlia are more uniformly mounding than plants of the parent selections.
Plants of the new Dahlia can be compared to plants of Dahlia ‘Fidahhypre’, disclosed in U.S. Plant Pat. No. 21,252. In side-by-side comparisons, plants of the new Dahlia differ primarily from plants. of ‘Fidahhypre’ in the following characteristics:
    • 1. Plants of the new Dahlia are more compact than plants of ‘Fidahhypre’.
    • 2. Plants of the new Dahlia have larger inflorescences than plants of ‘Fidahhypre’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Dahlia plant showing 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 is a side perspective view of a typical flowering plant of ‘Dodahhypelpin’ grown in a container.
The photograph on the second sheet is a close-up view of a typical inflorescence of ‘Dodahhypelpin’.
DETAILED BOTANICAL DESCRIPTION
The aforementioned photographs and the following observations and measurements describe plants grown during the late summer and early autumn in 13-cm containers in a glass-covered greenhouse in De Lier, The Netherlands and under environmental conditions and cultural practices which approximate those generally used in commercial potted Dahlia production. During the production of the plants, day temperatures ranged from 24° C. to 30° C., night temperatures ranged from 18° C. to 20° C. and light levels averaged 600 watt/m2. Plants were ten weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
